I have a pip4048MS , i'm duplicating the @hbpowerwall configuration, now i want to add a BMS, probably Batrium, but how it's connected the BMS if the same 2 wires are using to charge/discharge the battery??
Can some one made a little diagram to help me?, i don't know how to connect a BMS...
I read a lot of material about the danger of DC current, but i don't know, if the powerwall that we are building are dangerous to the people.
I mean with 48V you can touch positive and negative (in a installation with 150 Ah)??
I know that this has not easy answer but... any help will be helpful.
