Traduction de l’étape 7
Unwrap and conserve the (hopefully functioning) power controller board from the old battery by cutting the tabs. The tabs are thin and soft and cut easily with a razor. Disconnect the positive terminal first. I used a voltmeter to find that the battery case is positive.
I trimmed the tabs about 1/8" from the board, just enough remaining so that I could later fold them over the wires of the new battery.
