Extra battery

We've had car batteries for years in our platform sidecar, but always get rid of the motorcycle battery completely. They work hard and the power reserve is excellent. They usually cost less and last what seems forever.

fuse block accessories are nice because they are connected to the stock size. I've always connected to the original ground and positive lead-acid battery positions on the bike, use generous size of the battery cables. Amperage discharge its existing motorcycle accessories is covered by an appropriate fuse or circuit breaker.
