Review on MIAZA Circuit Breaker Trolling Waterproof by Sean Maples

The Miaza circuit breaker can perform a shutdown function on smaller EVs (48 volts or less) to isolate the battery from the rest of the electrical system. I'm using this on an e-bike with two 20 volt batteries that max out at just over 40 volts. The switch actually serves three purposes. 1) It disconnects all battery power when I park the bike. 2) It's an emergency panic button that I can press in the event of an engine failure, and 3) I'm a circuit breaker that provides redundant protection along with the regular 30 amp battery fuse. At $17, this is a very useful addition to the bike.
