High Precision RV Battery Coulometer – 8-80V 50A
Ultra-accurate coulomb counting with ±0.5% precision for real-time monitoring of lithium battery charge/discharge cycles. Features a rugged ABS casing and industrial-grade shunt resistors for stable performance in extreme temperatures (-20°C to 70°C). Wide compatibility with 8-80V systems, ideal for RVs, solar storage, marine applications, and EV conversions. Backlit LCD displays voltage, current, capacity (Ah), and watt-hours simultaneously. Low self-consumption (<10mA) with built-in anti-interference design for clean data in high-noise environments. Directly connects via 50A high-current terminals with gold-plated contacts to minimize resistance. Certified waterproof (IP65) and shockproof—engineered for off-grid adventures. Bulk pricing available for fleet operators and renewable energy projects.
