Default Re: Secondary battery question

People put a second battery in for stereo systems all the time, it does just what you said. If it takes longer to run them out than your function you are good, just drive it or charge it before you do another show/parade/etc. I would wire the second battery with larger wire is all, maybe 8ga or something in case the primary gets low and power comes from it mostly. Be careful the wire is protected and can't short out. It should be fused at each end on the positive wire, but cart is so small not sure it is necessary. Also note the frame is not ground on these carts unless you make it ground via wire.

You can also try to use LED lights when possible, current draw is considerably less. Amazon and ebay just to name a couple, have a huge selection of lights.
