Under discharge 1 cell went low

What could be the reason?

Could it be the point in the battery string to which i connected the inverter? Maybe its better to connect it to the middle of the battery bank?

I will try to attach pictures

Re: Battery arrangement 48V 65 cell Hailong 3

Thank you!

yes its very odd the measurement done by the watt meter but the good news is the kit meter shows 3 leds insted of 1 at the begining.

I will do a drive test and see how far It can go. kinda myth buster´s tests.
