I need Help with my Batteries

EDIT: I just saw that this thread is already 3.5 weeks old. But perhaps someone else finds the table I posted helpful..?


Perhaps the following chart might help you. It's a screenshot from a german website, but as it's rather self-explanatory it should be understandable, so I haven't edited it.

But to make sure, here's a quick and free translation by me:
"The following table shows which continous discharge rate (CDR) the batteries need to have for which power setting. (...) To extend the life span of the battteries they shouldn't be used constantly at their maximum limit."
"Akku" is german for "rechargable battery".

So in your case you would go to the 40W column and to the "2X Akku" line (as your device uses 2 batteries) and you see that the load for the batteries is around 7 Amps.

Lost Vape Centaurus G80 AIO by Infinium

cH24IxH.png


Another look at Lost Vape, which after a long series of pods and box mods, dives back into the AIO scene. After trying their hand at a BB-inspired model, this time they follow the trend that currently dominates the AIO world: an ultra-open design aimed at tackling the most annoying issue around — condensation. The Lost Vape Centaurus G80 AIO is being offered for free by HealthCabin, with no money being exchanged or employment relationship involved.

Measurements of 82 x 31 x 48, 116 grams is the weight without the battery, with one of the two inserted it reaches approximately 150 grams. Aluminum for the body, PCTG for the panels.
Inside the box, you basically get everything: the Centaurus G80 AIO, two drip tips, a key tool to unscrew the nut, a bunch of spare o-rings, a USB Type-C cable, a chimney reducer, user manual, and warranty card.

The first setup lets you run the G80 with stock coils, using an empty UB AIO pod, a UB Ultra M7 0.2ohm coil, and a UB Ultra M8 0.15ohm coil.
Then there’s the rebuildable section, including a Centaurus Boro tank paired with its RBA, two extra airflow pins (plus one pre-installed), a screwdriver, and a base to help you prep your first build.

The top section features a reinforced metal plate to strengthen the structure of the Centaurus G80, secured by four screws and engraved with the Centaurus logo.
You’ve got two nut options here. The first one includes a standard 510 connection, letting you use any drip tip with a 510 base — from the included ones to your favorite RTA tips. It comes with two slots so it can be easily removed using the provided tool.
The second option is a nut with a built-in drip tip, more geared towards a flavor-focused experience.

As for the bottom, it’s wide and very stable — even more so than the B80, which already had solid footing due to its weight. It’s secured by four screws and marked with CE, disposal symbols, and “designed by Lost Vape”. Just like on the B80, Lost Vape makes it clear they’re not keen on battery recharging directly in the device — the USB Type-C port is placed on the base as a subtle hint.

The battery door is made of PCTG and snaps onto the frame via magnets. Its design features several slots. Not enough to fully show off your battery wrap — as the AIO trend goes — but it does block out most of the grime, keeping the battery compartment cleaner.

XT6q9hb.jpeg


The battery bay is quite roomy. Just a few extra millimeters and it could probably fit 21700s. The extra space is clearly intentional, making it easy to insert and remove 18650s. For aesthetic reasons — since the battery area is partially visible — Lost Vape even skipped the usual pull tab that's on every box mod I've tested from them, including the Centaurus B80. The spring-loaded gold-plated contact is very flexible, making battery removal easy. The battery is inserted positive side down, as indicated.

j3R4FBh.jpeg


The front panel is made from polycarbonate, the same material used in Lost Vape's full-body P and N series boxes (P200, N100, N200). They're clearly confident in its durability — my Centaurus B80 panels are still crack-free after a year and a half, just with a few surface scratches. On the G80, Lost Vape went for a “diagonal striped mechanical” look: 5 cutouts on each side and the front to reduce condensation and ensure airflow even if part of the intake gets blocked when gripping the mod.

The fire button is placed on the top side — ideal for thumb firing, especially for users like me who feel that some AIOs are oddly laid out for right-handers or are actually more comfortable for left-handed vapers. The button itself is quite large and satisfying.

W4DconA.jpeg


The dual spring-loaded contact system, previously seen on the B80, is back. Similar to what you'd find on pod mods, it ensures accurate readings even with third-party boro tanks, not just the two included with the G80. The OLED display is just 0.42 inches.

SJDi1lw.png


As for the chipset — I haven’t seen confirmation that it’s the usual Lost Vape Quest chip, but functionality-wise, it’s basically a stripped-down version of the one used in their main box mods. The small display size obviously limits the information shown: battery icon, wattage, a 4-digit puff counter, and coil resistance. Wattage can be adjusted from 5 to 80W.

Controls:
- 5 clicks on the fire button: power on/off
- 3 clicks on the fire button: switch between "smart" mode and RBA mode
- Fire + "+" button: locks the wattage buttons (fire still works)
- Fire + "−" button: resets the puff counter

Minimal chipset, offering just two modes: Smart and RBA. The difference? In Smart mode, the device auto-sets the wattage based on the coil's resistance. RBA mode, on the other hand, doesn't feature the kind of "boost" you'd find in Lost Vape's box mods — that fine-tuned regulation designed to better handle complex coils is absent here.

B4JAbE7.jpeg


The first setup option for the Centaurus G80 is the UB AIO pod (on the right) — a "structure" designed to support (some of) the UB Ultra prebuilt coils. The one included in the G80 kit is made of transparent PCTG, though a smoked version is also available aftermarket. All versions, including the stock one, hold up to 5 ml of e-liquid. A key selling point here: no need to mess around with swappable pins or settle for fixed airflow — the draw is adjustable via a dedicated airflow ring.
The refill port is sealed with a silicone plug that fits chubby bottles too. It might be a bit stiff at first, but loosens up with use and becomes easier to handle.
The UB Ultra coils are press-fit, so be gentle when installing them. Even though the base around the coil port is decently thick, it's still PCTG after all.

g1lyDfN.jpeg


Coil offering mirrors the one found in the B80 kit, giving you three UB Ultra mesh coil options:

- M8 – 0.15 ohm (60–80W) → Included in the kit
- M7 – 0.2 ohm (40–60W) → Included in the kit
- M6 – 0.3 ohm (30–40W)

Realistically, you're only getting two usable coils, since the M8 is a bit too much to handle with a single 18650. Once again, the more reasonable and interesting M6 isn’t included. The M7 gave me the same impression it did back in late 2023 — a solid flavour coil for a pod that benefits from a 5 ml capacity. It responds quickly even at 37–40 watts, and with a good 18650 battery, the runtime is definitely acceptable.

6o5eOiA.jpeg


The second, much more customizable option is the Centaurus Boro Tank with its dedicated RBA. Also made of transparent PCTG and with a 5 ml capacity, it can be refilled either via the top plug or — my preferred method — from the bottom, which is more convenient and forgiving even if your wicking isn’t perfect. There's also a tiny notch on the PCTG body to help with removal, which doubles as an indicator for the correct insertion direction.
When taking it apart for daily use, the upper chimney section is connected to the chimney/chamber combo through threading and an O-ring, while the chamber and the deck have no O-rings in between.

D1QB23g.jpeg


The deck is pressure-mounted onto the metal base, and the seal is maintained by O-rings — same goes for the entire PCTG structure.
In more advanced usage, you can remove the airflow pin or use the base to fire up the coil during setup. The airflow pin and positive pin are a single gold-plated piece, available in 1 mm, 2 mm, and 3 mm sizes, held in place with threading. Unscrewing the pin will also release the positive post — so make sure to handle this step carefully, especially if you've already installed your build.

6UgObW8.jpeg


Parallel posts, flathead screws, and the airflow pin sits flush with the deck. It features dual wicking slots where cotton should be laid following the usual rule: no stuffing, no floating ends — otherwise pressure will shift the cotton and you’ll end up with leaks.
This atomizer leans toward an open MTL with the 2 mm pin, or an RDL draw using the 3 mm. The 1 mm pin, as I mentioned in the B80 review, feels more like 0.9 mm and is honestly forgettable. It handles creamy, fruity, mentholated, and flavored tobaccos well. For NETs, I'd probably look elsewhere.

VnhlInL.png


This is a kit that floods the user with options. One mod, one stock coil atomizer, and one RBA with boro compatibility — each would cost you no more than $15 if bought separately. Plus, you get free drip tips, two coils, and a bunch of accessories. If you're looking for a budget-friendly AIO for travel, or just want to dip your toes into the AIO world without breaking the bank, the Centaurus G80 is a solid choice. You get the full picture, both with prebuilt coils and the included RBA — just like I did with the B80 kit from Lost Vape, which taught me the ups and downs of this whole AIO scene.

The Lost Vape Centaurus G80 AIO is available on HealthCabin along with coils and accessories: https://www.healthcabin.net/lost-vape-centaurus-g80-aio-pod-mod-kit-p/30074.html

Bench Test Results: “EVE 50PL” (unconfirmed) - 50A/125A 5000mAh 21700

These tests below only note my personal opinion for the ESTIMATED ratings for the batteries I tested at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, EVE, Lishen, BAK, or Sanyo can change at any time! This can be one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of property damage, personal injury, or even death. Never use them outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous discharge rating (CDR), never let it get colder than 0°C or hotter than 60°C to help lower the risks and extend cell life, and keep the plastic wrap and top insulating ring in perfect condition. Never use a battery that is physically damaged in any way.

Testing batteries at their limits is dangerous and should never be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.

Test Results
YOU USE THESE CELLS AT YOUR OWN RISK! We do not know for sure if these are actually EVE 50PL’s.

These are allegedly pre-production samples of the tabless EVE 50PL but might be “rewrapped” (not in factory wraps) since “EVE” is on all their other cells but not these. These have the same bottom laser-welding spiral as the 40PL though.

There is an unconfirmed rumor that the EVE 50PL has a short cycle life due to it being created for use in military drones. This is where absolute max performance is critical and compromising that to ensure decent cycle life isn’t needed.

I don’t know if this is true or not but if you use these cells and feel their performance “fades” faster than than expected please let me know. I did some preliminary cycle life testing and didn’t see any fast degradation though.

Just for reference…the Ver. A datasheet for the EVE 50PL has no cycle life spec. The 40PL’s Ver. A datasheet does. Pajda, a highly respected tester at the Endless Sphere forums, and I will be testing cycle life but that can take up to a couple of months to finish.

On to performance…at 20A and higher this cell equals or beats any other small round cell I have tested. At above 20A, up to 50A continuous, this is the best performer I’ve ever tested. Check the Ratings & Performance table for the numbers (link below).

I’ve done a 40A and 100A continuous “shootout” against the other top four 21700’s but the results are Patreon-only.

If this cell does have decent cycle life then the performance could definitely make buying this cell worth considering.

Thank you DIY500AMP.com for donating cells for testing!

Some specs and observations…
  • Datasheet capacity specs are 4800mAh Minimum and 5000mAh Typical.
  • The five cells I tested measured 4985mAh-5011mAh with an average of 4994mAh, just below the Typical spec. Not great consistency but okay, especially if these are pre-production cells. Considering the differences in equipment I consider these cells to be meeting their spec but would prefer to see them hit around 5100mAh like many cells from Samsung and others would (for a 5000mAh-rated cell).
  • DC internal resistance was 6.4mOhms to 6.9mOhms for five cells. This is decent consistency.
  • I estimate its current ratings to be 50A continuous with a 125A temp-limited (to 80°C) non-continuous rating. Never let the cell go above 80°C at any time if using a thermocouple for temp sensing or above 65°C if using a thermistor (which are VERY slow)! This includes the temp rise that can still occur after a high power discharge has stopped
  • Standard charge rate 2A, max is 10A but I am sure that will shorten cycle life.
