Yeh and that's a a large banana
So it's def. a chunker.
I chose 300A because.. well better over dimension the bms instead of having it being the weakest link.
Also.. what I read online, these are actually very decent management system, very reliable.
The instructions I found aren't actually lining up between the explanation and what is pictured.
"start wiring from the first bc0 on the right, the first wire is connected to the battery negative terminal, and the second wire is connected to the battery negative terminal, which is the first battery positive terminal and so on"
I suppose that should read :
"start wiring from the first bc0 on the right, the MASSIVE BLUE WIRE wire is connected to the overall battery negative terminal, and the first wire on the BC0 connector is connected to the FIRST CELL NEGATIVE , the second wire on the connector is connected to the first cell positive, the third wire is connected to the second cell positive and so on"
.. until you hit the 15th wire on (i guess it's called) BC1, which you combine with the 16th, 17th, 18th and 19th wire and connect it to the 14th cell positive, connect the 20th wire to the 15th cell positive and finally take the 20th and 21st wire and connect it to the 16th cell positive
