Maybe they’re just shipped with lower voltage. battery capacity testers are like 15$
Rrr then again that’s really low. Like damaging low I think
Batteryhookup has always sold me great stuff.

Charge SLOWLY and check cell temperatures every few minutes. Then leave the pack for at least an hour so the voltages can settle, record the cell voltages, and then check the cell voltages after letting the pack sit for a week.
Any cells that have dropped to a voltage a lot lower than the others are most likely too damaged to use.

Isnt there a rule about shipping 30% soc so maybe that could impact it.
Thanks for the tips, was completly awarre of chraging going to slow charge to wake them up a bit. Ill definitely test the pack before i implement it. Ie, charge, sit, test, charge, sit, slight discharge, etc…

The modules i purchased use a proprietary bms thing, i think the voltage of these packs could be higher, but i need to figure out the wiring for main positive and negative, charge, etc.

I retested and found main positive/negative. Cells appear to be healthy at 20v in 6s

Hey you ever get these batts up and running? Im starting my battery build and was wondering if you figured out how to activate the bms or bypass it through the mr30s.
Thanks.

I have not, had a bunch of life stuff going on these past couple months and this project got shelved for a bit.

No extraction needed and new for 1.25$ a cell.
Are these the most powerful cells in 26650 size?
Fastest charging and many cycles at least

So cheap 
Ridiculously cheap. Tempted but looking at the housing, the difficulty with recovery is gonna negate much of those savings. They even say in the description “or you can always try and recover these cells”. Basically “good luck” lol.
