I have been asked to have a look at an inverter that only seems to charge and discharge at 2.5kw. the inverter should be able to pull higher around 5kw. The inverter does read the battery BMS. I think it's on the wrong profile on inverter. The solar installer advised there is other profiles but...

My seplos BMS is not reading the right side of cells. So was trying to start charging the cells to I got a new bms.

I have a 60v 5amp bench power supply. I currently have 16 cells in series and a neey 15amp balancer. Looking to bypass the Parrallel charging as it takes a week to complete. What is the best way to connect so I don't damage any cells or cause sparking. The pack is currently at 51v.

I use a seplos BMS in a case from EEL they have the balancer cables integrated to PCB boards and it throw the seplos out whack. They are set to trigger at 3.45 and it never charged to unit this morning.

Looking to buy a neey active balancer 15amp and have been told if I can take 5 the price reduces massively. About 30% less a unit. Looking to see if anyone would like on. These are coming from a EU warehouse would have them in about a week ready to ship to any suitors. Cost is around £225...

EEL supplied me with 2 2amp active balancers they advertised as jk. But the jk bms app does not seem them during a scan. Is there a different app for them.

seplos v3 might have given you different results. you could try and flash the bms or check to see if that are all using the same software version.

That is slightly different have you tried disconnecting them and run as individual battery see if issue remains. Have you got home assistant or look at monitor logs to see what each cell does it and under what load.

Charge to 100% grab reading of cells. See if they close to 3.4 after charge ending. Disconnect the Comms and try a drain of battery see what is drains. The inverter might have to go to lead acid mode to stop the errors. Failing that strip down and manually charge the cells

8mm lug and bolt on it

Some pics added

2 different boxes

the damage was not too bad i have seen a few delivered to me much worse.

The inverter can only use 100amps should 25mm not be fine for that.

both ends of the positive terminal seems to be burnt, going from the isolator to battery positive and when case is open the positive to bms.
