Just bought some life po 4 batteries with the aim of making a power bank..or something. Looking at the chargers has completely screwed my head up, pls halp Laughing

The batteries are 3.3v 6ah 38120 cells, 8 of them. I don't need them all on charge at the same time.

I may try and put them in a car charger pack I have with a duff battery, assuming I get my head round the wiring for them and the BMS thingy.

Currently looking at these two. They seem to do the job..or do they.

Depends how you're wiring them. The chargers you've specified charge up to 6S which is 6 cells in series. You can have whatever you want in parallel up to the current rating of the charger.

If you're making a car charger pack you'll probably go 4S2P as in 4 in series by 2 banks for 8 in total. You'll then need a 4S BMS that can handle LiPo batteries (which have slightly different characteristics to Lithium Ion.)

Making a jump pack... that's a LOT of current you'll be chucking out. Hope you know what you're doing Shocked

I dont mind charging them seperately..first thing is to get them charged, and aye the BMS! Can't wait Neutral

Either of those will charge a Life Po. In fact many of those sort of chargers are the same internals, just branded/cased differently. I've got an older version of the Accucell-6

Lot's of fake B6 chargers around, including the Haisito one you linked to:

Was a popular charger in Airsoft/RC which is probably why it was copied

Genuine one can also be had from Hobby King

I noticed a lot of fakes and I'm paying attention to reviews -Amazon is useful for a change.

Cheers.
