Any help will be appresciated. I am building a solar powered electric sailboat.

I have 4 24v 60ah Lifepo-4 batteries from Foxwell Technoligies in China (they are not much help) each with there own built in BMS, wired in series parrall for 48v 120ah. Attached diagrams.

When I discharge the bats 1,2,3 drop in voltage but 4 stays the same as if it is not discharging. When I disconect bats 1&2 - 3&4 still give out 48v but 3 discharges more than 4?? if the BMS in 4 is bad the set should not be putting out 48v??

Thanks John
