The BCM1210-3 is a high-performance, fully waterproof triple-output mains charger designed for marine applications, including yachts and canal boats. With a total output of 30A (10A per output), this advanced charger is compatible with a wide range of 12V battery types. It features intelligent multi-stage charging, a dedicated battery repair mode, and multiple layers of electronic protection to ensure safe and efficient charging. The IP68 waterproof rating makes it ideal for harsh marine environments, providing reliable charging in all weather conditions.

This charger allows you to charge up to three batteries simultaneously while offering intelligent diagnostics and repair functions for deeply discharged or damaged batteries. Its intuitive LED power display provides real-time charging status, making it easy to monitor battery levels at a glance.

Key Features

- Fully waterproof (IP68-rated): Designed for marine environments, this charger is completely sealed against water, dust, and moisture, ensuring long-term durability and performance in harsh conditions.

- Triple-output charging (30A total): Supports charging up to three separate 12V batteries simultaneously with a 10A output per battery bank, making it ideal for multi-battery systems on boats and yachts.

- Wide battery compatibility: Works with multiple battery types, including Sealed Lead Acid (SLA), Wet Cell, Gel, Enhanced Flooded (EFB), Maintenance-Free (MF), VRLA, AGM, LiFePO4, and Calcium .

- Comprehensive protection system: Features built-in safeguards against reverse connection, over-temperature, short circuit, and overcharging, ensuring safe, unattended charging.

- Intelligent grid power display: Five LED indicator lights display the current charge level at 20%, 40%, 60%, 80%, and 100%, allowing for easy monitoring of battery progress.

- Battery repair mode: When the battery voltage ranges from 2V to 13.2V, the charger initiates a high-voltage, low-current pulse for 10 seconds to assess if repair is needed. If the battery voltage exceeds 15V, it enters repair mode, and the repair indicator lights up. Otherwise, normal charging begins.

- Force Mode for charging dead batteries: If a 12V battery is completely dead (below 1V), the charger activates Force Mode, delivering a low-voltage charge for 5 minutes to revive the battery before continuing with standard charging.

- Easy operation with mode selection: The charger includes a Mode button to switch between different battery types and activate the repair mode as needed.

- Complete accessory kit: Supplied with battery clips and connectors for easy setup and secure battery connections.

Compatibility

The BCM1210-3 is suitable for use with any 12V SLA, Gel, EFB, MF, VRLA, AGM, LiFePO4, or Calcium batteries. It is not compatible with 24V systems or a combination of 12V and 24V batteries.

This charger is supplied with 6 ring terminals, 3 pairs of battery clips, 4 mounting screws, and a mains AC cable with a UK 3-pin plug.
