That's good to hear. I'm using my thunder AC6. I gotta figure how to incorporate the balancer so I can charge 2 cells at a time.

Also do some batteries as in different brands end at a different voltage. 4.1 or 4.2v

I don't think the .1 difference in voltage would matter much, but do the math on the charging rate. Most chargers that have a balancer are for 2+ cell batteries and aren't for single cells.

I have been wondering the same thing. I was big into RC planes and helis for a while and have alot of excellent smart chargers for lipo/lion. They all have deans connectors on them but i am sure i could rig something.

Also wondering if its completely crazy and unsafe to use a lipo pack to build a mod? I am guessing thats 100% a yes lol.

U would need a low voltage cut off but...LOL! I would think that using a lipo would be like smoking a stick o dynamite.

I have a Onyx 235 charger I use for my RC battery packs. It's a great charger and I could have rigged something up to charge my PV cells. Didn't think it was worth it though. Just the size of the setup was a turn off for me. I bought a Xtar 2 and am very satisfied with it. It's small, does 2 cells at a time, it's safe and I think I paid around $15 for it.

If you do use a hobby charger, be careful not to charge too fast. Lipo's these days can be charged at 2C, but I still only do 1C with mine, so one hour per charge. Lion's are I think are 1C max for charging, so I try to stay at 3/4C max.

I've had that thought too bandroidx. The increased output capacity of these batteries would be nice if there is limited room, but that also means they wouldn't last long between charges. Then there's the issue of the fragile construction. I also don't think you can get them with contacts at the ends, but I could be wrong. Lipo's used in RC are also not protected. We depend on other gear for low voltage cutoff, but if we discharge too fast, we kill the batteries and sometimes they burn. All of this can be overcome safely, but is it worth it, especially when lion cells are so cheap? That's what has kept me from pursuing it.

A hobby grade charger is way safer than these $2 wall chargers they sell for e cigs. A safe formula is 10% of the mah is the charge current to be used. Example is a 1200mah battery is charged at 1.2 amps an 800mah battery charges at .8 amps etc.... The chargers as long as they are set correctly are super safe, most won't even let you set them wrong and shut off if they are set incorrectly.

As a side question, where do you guys get the charge leads for the ecig batteries?
Thanks, Joe

jnslprd, a hobby grade charger is only safe if you know what you are doing with it. They have too many settings that can get people in trouble if they don't understand them. The little chargers are generally pretty good.

Your formula is not correct. Voltage does not change, mA does depending on battery mAh and charge 'C' rating and there are other details involved also. If you want to learn more about this, you can't go wrong starting with The Battery University site here.

Hobby chargers do not have leads available for ecig batteries. We would have to make them ourselves along with a fixture to connect the leads. This is definitely not a good idea for anyone who does not totally understand the safety issues involved. Be safe and vape happy!
