Amazing build and thread! Loved reading it!

This build really highlights how you can make cheap parts work reliably if you put the effort into fixing them.

What current draw can those cells do btw?

Thanks man… very appreciated! It took some time to put the thread together. Many many pictures had to be left out or it would never end :smile:

Indeed one can make something nice for little money if you are dedicated and don’t stress to much.

The cells should keep up pushing 200A for a couple of seconds

Awesome Build , I have a unity that the anti spark when on. Is there any chance you could talk me through your bypassing of the anti spark. It is a skill i would like :slight_smile: Thanks

Sure here are the steps

First remove the heatsinks… then,

  1. Remove plastic connectors or shield them off. It’s easy to burn them otherwise. Try also shielding the capacitors… the cover on them tend to crack easily.

Use hot air station

  1. Remove broken gate driver IC.
    Remove four gate resistors.
    Crank the heat up and remove the four Antispark FETs. This can be tough since the heat is just sucked away into the PCB.

  2. Bridge the FET pads with conducting material. I use a piece of copper busbar. Others have made simple solder bridges (not sure if that is a good idea). Perhaps nickel will do fine?

  3. Good flux and solder are your friends.

  4. Check that other components have not moved.

  5. Check no shorts

Small update, did the bike tire mod on the boa wheels as well. Same as the Rat. I know it’s nuts, don’t tell me.

-Sketchy at high speeds.
-Comfortable rolling on winter gravelled swedish bike lanes.
-battery consumption took a hit as expected.
-I wanted smooth tires (not off-road). Hence they were really thin. Probably won’t last long.

I do this so you others don’t have to :laughing:
