Sigelei Zmax V3 and V5 Telescopic: User's Group

[JeremyR]

Mine always come out with the top one only .02 off from the bottom. The efest red are almost a year and still equal. But thier capacity has dropped, but its also been more than 300 charge cycles... What you watch for is one battery to fail before the other.. Or start to have a reduced capacity..That battery would fail/reduce sooner on its own anyway. I do not believe it has anything to do with stacking.

To go over 15w you do use voltage. 6v will put you up to 24w.

Side note- the AWT batteries I tried don't seem to be as good as I hoped.. They seem to be going south quickly. Not much better than year old efest it seems...

My v3 doesn't get hot.. Maybe its just your Atty and it transfers to the stainless. The heavy gauges stay hot a long time and transfer throughout the Atty.

I'm also looking at upgrading to a 50w or higher. eleaf 50w maybe, maybe a sigelie.

I've had very good luck as well with Efest reds. I use them for 6.5W to 7.0 watt vaping. I have purchased two sets of four Efest red flat top 18500s. Of the first set: one 18500 lost enough capacity to be replaced at about 270 charge cycles. Another crapped out a few days ago at about 350 charge cycles. The other two are still going at at about 350 charge cycles. The second set of Efest red flat top 18500s were purchased last fall and they are doing just fine.

My 18350s came in a purple box but they are red and state V1, 800mah. The 18650 3100 are purple tho.

Sorry if this is off-topic, but I thought it might be overlooked since we're on the subject of batteries.

I'm not currently keeping track of my charge cycles, but I'm thinking about starting once I replace my batteries again. I'm curious how others keep track and what works best for them. In the past, I've kept track of charge cycles at work, but those batteries were much larger and it was easy to place a large sticker on each battery where we could make quick annotations to represent charge cycles.

Since these batteries are relatively small, would most of you recommend individually labeling each battery and keeping track on a separate sheet of paper? This is what I'm leaning towards, but wanted to see what most of you were doing first.

Thanks ahead of time for any thoughts or comments!

I had a great sticker I made for my lipos back in my rc days. I'll see if I can find it but it was a table with 100 squares (hi power lipos wouldn't last longer than that back then) and I would cross out a square with each charge (when removing from charger). It was child easy to see at a glance how old / worn out each lipo was.

Efest red flat tops are V1, button tops are V2.

My method is a conservative estimate. I am very regular about my vaping habit and go through the same number of 1100mAh 18500s each day. For the first set of four Efest 18500s my estimate is pretty good. They were the only batteries I used until I bought a second set of 18500s. I keep the batts in two rows, side by side. One row is charged batts, the other is batts that need recharging. Charged batts enter their row from the left and leave for use on the right. On the depleted battery row new arrivals are placed on the left and batts leave for the charger from the right side. I used to charge two 18500s at a time back when I had four of them. Now that I have more I charge four at a time on the i-4.

It would be better to keep a written record of charge cycles but I'm not that fussy

There are slight differences between the two sets of Efest red V1 18500s I have. The first set was purchased in April of 2013. There is a white circular area around the positive terminals. The second set purchased in November 2014 has a black area around the positive terminal. In addition, there are slight differences in the label style between the two sets.

I am using tiny 240mAh 1S LiPos with my micro quadcopter. I keep them in rotation, too. From what I've read on the RC forums the LiPo cells are good for about 100 charges at best before they suffer serious loss of capacity. IMRs used for vaping are said to be good for 300 charge cycles but consider the higher drain possible with LiPo. Those things crank out 25C. The new AW 18350mAh is only 15C.

I have several lipos rated at 70C and "serious" loss depends on the eye of the beholder. Some of my friends used to dismiss any lipo with a 10% capacity loss. No good for competition" they used to say. I had lipos last more than 100 cycles but they usually never had suffered a discharge rate beyond 4C (8 amps). My mains that had to give everything in 4 minutes and 20 seconds, barely made it to 100 (unless they burst or inflate before) with a 20% percent capacity loss and where refurbished then to lower power applications or where failure didn't matter much (starter batteries for example)

70C is just awesome. I'll bet those guys heat up fast.

 

[tchavei]

Yeah... I have a glider putting out 3KW/h (thats 3000W/h) for 3 minutes. It becomes scary when you think about the power stored in those lipo packs.

I dropped out the hobby when my kids were born. I stopped having time but most importantly money to keep at it. Lipo packs like that would go easily for 400 bucks and I had to save the money for diapers

I think I've asked this in another thread , but which batteries fit best in 18350 & 18450 or 18500 (can't remember which) ... button or flat top? I'm getting the sig zmax V5 telescopic. It doesn't hv 2 different caps if that helps answer my question. If y'all hv best performance as far as brand and model numbers go, that'd be helpful too [emoji6] . I'm most appreciative!

 

[JeremyR]

All of those plus 18650 and 2 18350. All depends how long you want it to be. I prefer button tops in the zmax.

I'd prefer it last as long as possible without sacrificing quality. I guess a more specific answer would be at least 7 hours. I'm not a chain vapor but I do use my mod all day long. I usually average about 200 puffs a day, maybe more. I'm currently using an mvp 2.0 and charge it every 2 or 3 days if that helps. This (& the SVD 2.0 enroute ) will be my 1st removable battery mods so I hv currently hv no removable batteries at all. I did however order two Sammy INR 18650 25r 2500mah, two AW IMR 18350's, and two panny NCR18650B's but they are all flat top. From what I've read those should work well with my SVD but I'm worried about them fitting with my xmaz and wanted to be sure I had the perfect battery for it before placing any more battery orders. Do u hv any brands and models that you've found specifically work better for your Zmax?

 

[aikanae1]

Those batteries will do fine. My first choice is 2 matched 18350's. Keep them together and charge them together. I used 2 flat tops for the main reason that I don't get them mixed up with others - I also have a provari mini and that must have button tops. Makes life a little easier. You'll enjoy the zmax. I can get two days with it.

Thanks so much for the info! So I was considering grabbing some of the med length batteries (18500) just for an extra choice in unit size and aren't sure if button top or flat top will fit best. Any suggestions on that and a good brand and model in that size that could give me a decent vape time/ charge time?

 

[Kat Eyez]

[........] Sorry, I'm so new at the removable batteries, I have a lot of rookie questions lol

 

[Kat Eyez]

Btw, I'll Def be taking your advice on the 18350's. So do u stack them or just use 1 in the short mode? That might be a silly question [emoji55]...rookie here lol

 

[JeremyR]

2-3 days on an mvp... An 18650 will get you at your use about 1 1/2 -2 days.. The stacked, flat top, 18350 will be only a couple mm longer than a single 18650 and Should get you 3-4 days+ with more power than the MVP. Also it will be shorter than the svd in 18650 mode I think .

Stacked 18350 get me easily 2, closer to, 3 times the life of a single 18650. With full range of power up to 24+ watts at 6v & 4amps with 1.3-1.4 ohms. ( this power is not attainable with a single battery)

Its been said that imrs work better with regulated mods as opposed to the inr.. But I'm sure its only a small difference..

I have only used flat tops. And flats are best to stack.. ( single 18350 flat may need the spring stretched; without the small cap.. Depends on the battery manufacture.)

Efest have done well for me 18350s going on a year of stacking. Still good.

 

[PaulBHC]

Looking right now at my Z in stacked mode with deep cap and flat top efests at just under 5 inches and my SVD 2 with aw 18650 is over 5 1/2 inches.
