I posted this on another location on this site specific to the vendor in question but thought it might be of genera;l interest to anyone currently sourcing batteries. If it's bad form to post in two places, please let me know and I will try to remove one. I was recently made aware of this forum...

Active, continuous balancers for 3.2V Lithium Iron Phosphate cells. I purchased from Electric Car Parts Company and used for a year before moving to a different system. They have LED lights that indicate when they are charging or discharging a cell. They are the same as ECPC is currently...

I recently bought 3 of these wall mount Power Pros that are supposed to have 280Ah, 14.3 kwh capcity. I am wondering if anyone has actually run a capacity test on these batteries to verify the stated claims? I have capacity testers and would like to do that but it's difficult because the BMS...

Just thought I'd summarize and report back on my experience with Huanhuan Energy. I bought 64 "200Ah" cells from them on November 30th, 2019 and received on January 6th, 2020. Not until a premature low voltage shutdown in October did I suspect they were under capacity because usually they are...

I assume I am simply misunderstanding something but I am confused how EVE 280Ah cells can be about 71% the volume of CALB or similar 200Ah cells yet provide 140% the capacity. The CALB 200Ah measures 279x182x71mm which works out to about 220.2 cu in. The Eve 280Ah measures 205x174x71.5 or about...
