Redarc BMS1230S3 Battery Management System Caravan Trailer 4X4 Dual Battery Kit

REDARC — Charger

REDARC Charger. Supplied brand new. REDARC BMS1230S3 BATTERY MANAGEMENT SYSTEM CARAVAN TRAILER 4X4 DUAL BATTERY KIT.

Complete dual-battery charging, monitoring & maintenance kit

The REDARC BMS1230S3 is a complete battery management and maintenance system that intelligently charges and monitors your house (auxiliary) battery from vehicle alternator (DC), mains power (240V AC) and solar. An interactive LCD remote shows real-time status like charge completion, solar input and time-to-full, so you always know how much power you’ve got left.

Designed for today’s battery chemistries, the BMS optimises charging for Gel, AGM, Calcium and Standard Lead-Acid batteries—and it can manage a house battery that’s a different chemistry to your vehicle’s start battery. With a built-in current shunt for accurate State of Charge (SOC) readings, plus integrated protection and fault detection, it’s an all-in-one solution that saves time, space and installation cost.
