Tester for LIFEPO4 18650?

[RedBeard]

I'm building a battery pack with used cells and was wondering if anyone knew of a multi bank tester for LIFEPO4 18650 CELLS. I'm currently using a b6 clone but 1 cell at a time is torture.

If you are at all familiar with something like a raspberry pi. I made a system to test up to 8 cells at once using some ina chips a multiplexer and some resistors. If you are interested I can share some info.

Most definitely. I've been intrigued by the pies for a while now. Been wanting to make something with them.

Hello I'm new to this. I was wondering if I can get the plans for your battery tester also. I'm just getting started and was trying to figure out how to test used batteries. This seem to be the way to go, where I can test more than 1 battery at a time..

thanks in advance for all your help

when I was into 18650's I bought 4 liitokala's. people also like the opus. It would check 16 batts at 1 amp (changeable) in 5-8 hours. it also did a rough IR.
