1. Batteries are done with. They're 5 years old and even if they held a charge, I wouldn't trust it on the road. Time for new ones. As they stand now, my multimeter reads them at 6.8v apiece.
2. The controller is most likely busted since the connectors going from it to the battery and to the breaker were both fried.
I plan to put my old 500w cooler components into the 300w and wondering if it would be safe. Can you guys please chime in on your thoughts of the following setup? Will my motor fry by putting batteries that are 1.4ah over the motor's spec?
300W motor by United Motor, MY1016 model number. 24VDC, 16.4ah.
Controller: 24v (don't know the AH, figure that might be important?)
Batteries: Two 12v 18ah batteries
If you're curious how my new TAXI looks like:
I did consider overvolting this cooler too, but a couple things made me decide not to:
1. I already have existing components I potentially can use (will need to hear your feedback first on the above setup).
2. A third 12v 18ah battery won't comfortably fit in the motor/battery/component compartment and I really don't want to use up the space dedicated to actual insulation of drinks, baby milk, food, etc.
3. Buying 3 new 12v 12ah (or 15ah same size) batteries just didn't make sense if I have two perfectly good 18ah ones that would otherwise be just laying around.
I might overvolt later, but hoping to reuse my current components first.
