Connecting your motorcycle battery directly to your RV battery for winter isn’t the best idea. Here’s why:
Charging Differences: Your motorcycle battery is smaller and could get overcharged if directly hooked up to your RV battery. This might damage it.
RV Battery Drain: You might end up draining your RV battery, especially if the RV isn’t being charged regularly.
Safety: Directly wiring batteries together without specific safeguards can be risky (think short circuits or potential fire hazards).
What I’d Recommend: Stick with the battery tender you already use for the motorcycle. It’s made exactly for this kind of job, so it keeps the battery charged just right without the risks. If outlet space is tight, maybe add another outlet to your RV setup or consider a small solar charger just for the motorcycle battery.
