Can I use any battery with your Kits?
The answer is NO. It would likely blow the controller immediately on connection to the battery.
Others ask, “Can I use a 52 volt battery with a 48 volt kit?”. The answer is yes.
You can use any battery you like as long as the voltage is in the required range of what the controllers can handle.
Some kits are specific voltage like 24 or 36 volt 902 kits.
Some kits can handle a range of voltages right out of the box like the 901 can run at 36 or 48 volt and the Magic Pies can handle 24, 36 and 48 volts.
If you are going to use a Battery that does not have a BMS (Battery Management System) like SLA (Sealed Lead Acid) then you need the controller to be set to the proper voltage. This is to protect your battery. The controller will shut down before letting the battery drain down so low it could damage it. Please note that any of the vector sinewave controllers will need to be set to match the battery or they controller will not power up.
If you have a BMS in your battery like most lithium or LiFePO4 batteries have the controller can just be left at its default 48 volt setting and you can use 24, 36 or 48 volt batteries no problem. The battery will protect itself.
