hey guys I am interested in getting the vamo v5 but just was confused with the battery situation. I heard its maxes out at 5A so do you put in a regular 18650 or do you need a high drain 20a or 30a but i heard its pointless cuz it maxes out at 5a so nothing will happen

Well you answered your own question. Most 18650s will do although I'd stay away from the cheapest ones
Indeed. If you ever see yourself upgrading to a regulated device that can supply more than 15 watts, or an unregulated device, then you've done yourself a favor by purchasing batteries that can handle a little more current draw.
But, no, you don't need 20 amp batteries. However, I would at least go with decent 10 amp batteries, because it's generally advised that you not push your battery to its amp limit constantly. Also, get yourself a decent charger (Nitecore and Xtar are the ones I've heard good things about). Most batteries sustain the most damage charging, not while being used.
You absolutely need a High Drain IMR battery, however. These batteries vent, not explode, when something goes wrong.

You can't run the Vamo at much more than 11 watts on a single battery of any size. You need to use 2x18350 (stacked 18350s) to get the full 15 watts.
I don't have a Vamo, but use a Sigelei Zmax that operates the same way (same Yihi chipset). Sigelei amp limit is 2.5A for single battery, 4.0A for 2x18350. The amp limit is set by the electronics. It doesn't matter a bit if the single 18650 is a 10A or a 30A rated high drain battery or not, the APV won't let it discharge at more than 2.5A.

Has anyone one here seen what issues are caused with using cheap protected batteries on a vamo v5.
i have one that, on a volt meter, only fires at 1.55 volts no matter what setting you have it on. I am using a Ultra Fire 4200mah, low drain protected battery. But my local shop put one of their batteries in it and it still reads 1.55 volts. Not sure if it's bricked or just wrong battery.
Turns on
Reads Ohms correctly
Reads battery voltage correctly.
But doesnt fire over 1.55 volts.
i pruchased it with 2 18350's that worked great but since i put the in the charger i got with it backwards for an hour or so and burnt out the charger i can trust if those batteries are working still.

So didn't the shop tell you your vamo is faulty?
What voltage does the battery read on the voltmeter?
You can screw your regulated device up or completely ruin it running protected batteries in it. All the paper work in ALL my regulated mods state emphatically DO NOT USE PROTECTED BATRERIES IN THIS DEVICE
They also state to clear the device when switching from stacked to single.

^^^^^ That might be the problem : the pcb probably needs to reset to recognise the change from 8 volts down to 4 volts battery supply.
No, they were dumbfounded.
Cause everything reads normal but when you fire it the volt meter only read 1.55v. I believe the battery he was using was an orbtronics battery. The ones that worked until i screwed them up were 2 18350's 800mah.
This is what i had ordered- https://www.fasttech.com/p/1817101
I dont really want to go buy batteries if it's busted.
And im having a hard time believing its broken when everything reads correctly.
I can post pictures of everything when i get home.

To clear (reset) your vamo:
remove the battery cap
hold the fire button
reinstall the battery cap
Check all settings that you have done (RMS/Mean, Watts/Volts, etc)
Since this is a FT item, do a ticket on their site. They very possibly will replace it.
Good Luck

I put the ticket in but im sure they wont replace it. I had to fix the rubber grommet issue on this device already.
i probably fubar'd the batteries buy putting them in the charger upside down and i know for a fact the charge that it came with is shot "probably because of the battery mishap".
I believe their policy is that i would have to send back EVERYTHING. i have it all but as soon as they see i had to pull the firing pin to fix the grommet issue they will probably revoke the return and ship it back to me.
I just hope to god resetting the vamo will fix the problem. I'll try when i get home.

Reset it to no avail. This thing is shot!!
So you checked the batteries out then................
So the vamo reads the battery voltage correctly? So the batteries are good and reading over 4 volts?
What volt meter are you using to measure the 1.55 volts that you are reporting?
Does the volt meter you are using read the battery voltage correctly?
Maybe your voltmeter has a problem?
The vamo volt output is not a flat dc, so the meter reading depends on the meter.
Just checked my own vamo; it's reading 1.5 volts on my cheap multimeter when the vamo is set for 3 volts
and 6 volts when the vamo is set for 6 volts.
My more expensive meter isn't getting any reading at all- maybe I'm not using it properly; it's got a range button and a select button--- ah ok; in 'auto' mode it picked up the 6 volts with vamo set at 6 volts;
and basically nothing when vamo set at 3 volts.
If your vamo is set to wattage mode, it has to look for a coil before it decides what voltage to put out, so if you have it in wattage mode and trying to measure voltage you might not get anything.
So set vamo to 6 volts in voltage mode and then measure the voltage.
