Ok, thanks for your feedback. The battery box I've purchase also has the JK BMS with a 2A active balancer. So you installed all the batteries into the box and switched it on and leave it like that for a couple of day? What was your process? And was the charger/inverted already connected? And...

Can you explain this in a bit more detail? Is this about the charging profile of the batteries? And when you need to stop charging?

I've ordered MB31 cells (16x) they still have to arrive, no details on voltage yet. Assuming I need to balance them, which power supply or battery testing do you recommend? I've seen the blue device: EBC-A40L but this is another 200+ euro's. Any good alternatives?

I'm planning to build a battery system to store PV energy. I want to buy either EVE LF280 or EVE MB31 cells, 16 piece. I've read you need to balance them, bring them to the same voltage level, prior to start using them. Now I'm trying to find out how to balance them. The JK BMS has a 2A balancer...

Thanks for your feedback @rogerheflin . What I would still like to know and understand is how to balance the cells when the first arrive? When you unpack them from the delivery box. All cells are parallel connected and you need to put a power supply of about 3.6V on it. But how many Amps? And...

Thanks for the quick reply, appreciated. Good useful information. Do you have a BMS with balancing capabilities? In your situation is the balancer not taking care to make that cell equal on a voltage level?

Im based in The Netherlands and preparing to build a battery energy storage system with two purposes in mind, 1) use of the during the day generated solar energy in the evening and 2) to return (to sell) cheaper bought energy back to the grid for a higher price. For option 2 the dutch tax agency...

It will be a 48volt pack with 16 cells.

For parallel balancing, what kind of power supply are you using? Brand? How many amps? And what voltage are you using? Will this be one fixed voltage? Or does it need to be according to a LifoPO4 schema? Until what level do you need to balance/charge? Until they are full or they all are the...
