What size wire and length to solar panel. If you have 36v at inverter from 41.4v panel it's a 13% drop in voltage...you should try to keep it less than 3%.

Trying to make my life easier.... cleaning filters now is a breeze! Self adhesive magnet cut to size stuck onto filter material bought on temu. Airflow also improved.

The BMS will balance the battery over time....no idea what BMS is In the Shoto battery,or if there's a active balancer. It can take many weeks for a passive BMS with low balance current to get the cells even. Most batteries stert balancing at 3.45v per cell. Set absorption change to 55.2v...and float to 55v. At 3.45v per cell battery will change to about 99% full. And it gives the opportunity for cells that are at a higher voltage to balance. Also set change current lower...50A or less ... preferably 30A

Your battery probably is going into over voltage protection on one of the cells that's not balanced...on a new battery there can easily be a 200mv inbalance between cells. If just one cell reaches 3.65v over voltage protection kicks in.

Thanks PsyCLown! It's a JK BMS. I'm busy making the busbars with good old 22mm copper water pipe. Some might scoff at the idea,but it served me well so far. One just needs to ensure they are 100 % flat. I just have to decide if I'm going to nicke plate. I'll be using stainless washers, spring washers and nut torqued to 8nm.

I think the form factor is ideal for wall mounting. Can be used similar to these BYD blade batteries. Would have been nice if the clips and buss-bars were available.

Hi, bought 16 for a 48v build....all the cells measure between 3,291 and 3.294 v. Very impressed with the build quality of the cells and the service from altergrid. I've not capacity rested yet but Bertus from altergrid tested them to 187ah at .2c... he'll send you the full test graph if u want.
