I have a Bluenova 11Ah that I received January 2020. It has been sitting mostly idle since then - just a top-up charge once a year.
Warranty is over and I am curious…
26650 3.6 EDIT:[typo] 3.2V cells (manufacturer unknown) 3P4S.
BMS:
Bottom of BMS board:
Making some assumptions but looking at the bottom of the board I suspect about 50mA balancing.
Also, considering this particular battery has not been charged/discharged numerous times I get the following for the cells:
3.332V
3.330V
3.329V
3.332V
Looking at weight etc. to compare these types of batteries will likely not mean too much. This battery at least is filled about 1/3 with a rubberlike substance that keeps the cells from moving around.
