Hi Guys

Been lurking for a while and been learning a lot from Will and the community. I built a 2P16S 48v LiefPO4 battery pack with Daly 16S 48V 200A common ground BMS. They are connected to two Voltronic 4000W inverters in parallel. Inverter saying 55v on the panel while its charging and measuring 55v at DC terminals on inverter. At the battery pack I am only reading 52.2v and cannot get the pack to charge up higher than that. Do you think the BMS is trying to "protect" and limit charging?

Things I have tried:
Measuring each cell - all the same voltage.
Look for hot or bad connections - all seems in order.

Here is a short video of the build:

Looks like I found the issue, sensing cables 2 and 4 were switched around and thus the Daly would not let charge through. :D

Careful. Sense wires switched can kill the BMS.
Make sure it isn’t damaged.
