Inline Meter
thingiverse
I'm using this setup to convert from Anderson powerpole SB50 to Powerpole PP15-PP45 and insert a meter inline. It uses a 20 amp resettable breaker: https://www.andymark.com/products/20-amp-snap-action-breaker, and a 20 Amp max meter: https://www.banggood.com/PZEM-031-DC-6_5-100V-20A-4-in-1-Digital-Display-LCD-Screen-Voltage-Current-Power-Energy-Meter-p-1111791.html. The thin wall separating the connectors on the breaker tends to break until the cover is securely in place.
