48V mower

[DavidAB]

I am planning to use 4 12v car batteries. Is there anything wrong with using ONE of the 4 batteries which are in series to simultaneously power my lights or even to activate the contactor? I realize that this would probably unbalance the batteries.

Thanks

You might powr the lights and activate the contactor from separate batteries and segregate the load.

If LED's are used for lighting, some of the accept wide DC input voltage. You may be able to have a fully 48 Volt system. Same goes for the coil on the contactor.

I have run into problems doing that, one of your batteries will be pulled down and the others stop charging when they are full. There is a device made for electric golf carts that fixes the issue.

Buck converters are cheap these days and very efficient. Battery is expensive.
