Hello everyone-
Picked up cheap go cart and converting to electric (https://gokartsusa.com/Baja-49cc-Off-Road-Go-Kart.aspx) for my boys.
Picked up this and bench tested (https://www.amazon.com/TDPRO-Brushless-Electric-Controller-Motorized/dp/B075WT34MK)
I randomly have a bunch of 18v ryobi lithium 5-6ah batteries so my plan is to power with 3 packs in series. Probably won’t get a ton of run time but I have 8 and a 6 port charger. May convert to a dedicated lithium battery if this works. I could do lead acid? They aren’t terribly expensive but so heavy!
The controller is rated to 48v so I may blow It with the 3 packs. But I’ll be running it at medium speed so hopefully it won’t freak out. I can’t do 2 packs as the controller low voltage shuts off at 41v.
4 newb questions:
1) is this crazy?
2) I want an emergency battery disconnect. Ones that handle full 60vdc are big and expensive. Could I put a 24vdc 15a switch between packs 1 and 2 in the series as a cutoff? Any other creative safe solutions? I want my 10year old to be able to fully shut down without difficulty.
3) what max amperage can I expect?
4) what fuses would I get?
Thanks, LB
