Four Core Products, Covering Every RV Conversion Scenario

From driving charge and battery monitoring to temperature management and intelligent power distribution — four product lines form a complete, closed-loop RV energy management system.

Driving Charge

BiDC / CiDC Bidirectional Chargers

BiDC-X1 / X2 / X3 · CiDC-X1 (40A) · CiDC-X2 (60A / 1500W)

Bidirectional chargers: charge the house battery from the alternator while driving (ACC=ON), and automatically feed back 13.2V/80A to recharge the starter battery when parked (ACC=OFF) — plus one-touch SOS emergency start rescue.

Battery Monitoring

Blue Shunt Coulomb Meters

GEN1 / GEN2 · 200A / 500A / 1000A / 2000A

GEN1 local-LCD models (BMC series, 8–120V, optional Bluetooth) and GEN2 Bluetooth smart models — 8 SKUs in total. True shunt sampling replaces voltage estimation, so SOC stays accurate over the long term.

Temperature Management

Smart Thermostat

PID Control · Multi-Channel Relay Output

A precise temperature manager for RV hydronic heating, battery heating and refrigerator cooling — PID control at ±0.5℃, 2–4 independent relay channels, remote scheduling via Bluetooth APP.

Power Distribution

Smart PDU Power Distribution Unit

19" Rack Chassis · 15 Channels

A 19-inch rack-mount distribution hub: 15 independently controlled DC load channels, built-in coulomb meter, plus 4 water-level, 2 temperature and 6 tire-pressure inputs — all managed from one 7" touchscreen with offline voice control.
