Homemade electric kart

[ThreeCW]

I had another look at the Alltrax website and found the following statement:

I assume that you will have to use closed cell / gel cell deep cycle batteries in that cart. Open cell lead acid batteries would have an unacceptable leakage risk in your application (high speed / high G turns / limited or no suspension).

I look forward to following your build
