Based in China's automotive heartland, we provide highly reliable, cost-effective DC-DC charging, battery monitoring, temperature control and power distribution equipment for RV converters, energy-storage integrators and DIY builders worldwide.
Browse Products OEM / ODM Inquiry →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.
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.
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.
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.
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.
A national High-Tech Enterprise integrating R&D, manufacturing, sales and service — high safety, high adaptability, high value.
Years of deep work in battery management with 20+ patents and software copyrights covering coulomb meters, DC-DC power and IoT platforms.
Located in Changchun BeiHu Tech Development Zone, next to China's auto-industry cradle — mature supply chain, fast response, solid QC.
Parameters, logos, housing and function modules all customizable. Stock wholesale and drop-shipping supported for converters and exporters.
DCDC / ACDC / MPPT charging, coulomb meters, PDU, temperature and tire-pressure sensors — one stop for the whole energy chain.
Self-developed IoT cloud platform and mobile APP: cloud data sync, remote monitoring, alarm push and OTA firmware updates.
Professional engineering guidance, installation tutorials and after-sales service — from selection to installation to support.
Own facility in Changchun BeiHu Tech Development Zone. SMT placement, welding & assembly and burn-in testing — the full process under our direct control.
