Yes; I did. Also replaced three mosfets (2x K16A60W) and 6N60.

I cannot find a technical diagram so I hope there are other options to find de resistor values??

Option C. Buy any 6A lithium ion charger and chop the 5 pin cable and plug off the Giant charger. The CANBUS circuit is only needed for the 60% storage feature (?)

Any 6A charger? I have Bosch 36v 6A lying around and my wife's Liv charger just died. We're traveling with the bikes currently and a replacement charger cannot be sourced before go home.

Yes, any 6A DC 42V charger will suffice. Connect big Black negative wire (Pin #0) and Red positive wire (Pin#1) to the respective charger outputs. Thinner yellow, green, red Canbus wires can be cut off and isolated.

Using a generic charger might create problems you don't want to have, especially on Giant batteries.


@bobbyb ....if it's still of interest

If the primary side mosfets were blown, also check/replace the pwm/pfc controller.
