What type of charger are you using that you can adjust the voltage and amps?
-
I've got the larger 170amp version of these batts. They really didn't hold up. Just over half capacity after about 5 years. BMS must be junk. 5 of the 6 are still going but one had to be removed from bank because it wouldn't balance no matter what I did. $8k worth of garbage batteries. Atleast they can be replaced for a fraction of the price now.

This is extremely helpful. Thank you for posting this! I have two SOK batteries that have never been used completley depleated (I didn't know how to care for the batteries when I got them, I bought them and just put them on a shelf (climate controlled, for 2 years) until I was ready to use them). We weren't sure how many amps to try to charge them at when bypassing the bms so this helped us. Thanks so much. Also curious about the capacity test you were running, should i do that too?

I wonder what happened to them? cold temp charging, super low discharges?
-
I have an older BB 100ah that only puts out 52.4ah through Victron shunt.Bottom center of bat seems swelled.Or both sides of case got worn down?
-
I've got a 50Ah one of these. Left it for three months (after one month of ownership, the thing was brand new) - that's all it took for one of the cells to completely die. Stuck at 9V, even if you leave it on the charger for a week. Going to pull it apart and see what I can figure out. Downright rubbish products - I had to threaten them with legal action for them to honour their warranty. Any pointers?
-
Renogy is garbage, mine all had issues as well.
-
I had 3 of those, they're junk. The cylindrical cells run away, heat up, and lose capacity. Throw it away.
-
noooo. Too many volts on a single cell. each cell max is 3.6volts.
