So my Backfire G2 Black board battery would cause my bord to randomly turn of and then not wanting to turn on again, i’m getting a replacement from Backfire but tought that i could possibly fix this old one.
at first when i measured the voltage through the esc wire( the one that is going to connect to the esc) and the charging cable both were at 41v, but after i’ve opened the battery to check for any damage which could be the cause for the behaviour (short circuit or something) it is now constantly measuring at 16v
I’ve checked the balancing cable on the bms, pin by pin and all the pins have the same voltage so i know that all of the cells are balanced.
And when i measure the current directly from the battery pack i do get the 41v measurement. How ever, by measuring the positive wire directly from the battery and placing the other pin from the multimeter on each of the marked spot on each of these four things on the picture whatever they are i get a measurement of 41, except from the one makred red on the picture.
Does this mean that it could be this component which is faulty? so i can just replace it? Or must i buy a whole new bms?
It doesn’t look like there is any damage or shorted out component/wire from what i can tell, i’ve checked both sides of the bms.
What do you guys think?
Thankfull for any help!
