Switch & Fuse in Battery Circuit ?
I recently purchased a 4200XL ver 1.5 RC4WD excavator and someone recommended that I add an ON-OFF switch to isolate the battery (more convenient than unplugging all the time) and an in-line fuse for protection. I'm using a 6000mAh 3S lipo battery and am not sure how to calculate what amperage fuse and switch should be used.
Recommendations are greatly appreciated! Thanks. Ken

Lil Giants: Checked motor draw at hydraulic stall - it is 11A.
frizzen: Speed controller is rated at 60A. So, a 20A fuse and switch should be okay for this? Thanks for the help! Ken
