Battery Volt LiFePO4 12.8V 200Ah (200A) with BMS and Bluetooth, model 6AKLI20M20

Volt Battery Volt LiFePO4 12.8V 200Ah (200A) with BMS and Bluetooth, model 6AKLI20M20 is a rechargeable LiFePO4 battery designed for applications that require stable 12.8 V DC power and a high usable capacity. With a nominal capacity of 200 Ah and a continuous current rating of 200 A, this battery integrates a battery management system (BMS) that provides cell balancing, overcharge, over-discharge, short-circuit and temperature protection. Bluetooth connectivity enables remote monitoring of state of charge, voltage, current and fault conditions from a compatible smartphone app.

Advantages

This LiFePO4 battery delivers a high cycle life and a relatively low self-discharge rate compared with lead‑acid alternatives, reducing long‑term replacement frequency. The integrated BMS protects the cells during normal operation and helps maintain balanced cell voltages, while Bluetooth monitoring provides convenient status checks and simple diagnostics. The compact 12.8 V format and rated continuous current make it suitable for many off‑grid, mobile and backup installations where reliable DC power is required.

Suitable for

• Solar energy storage for off‑grid and hybrid systems
• Marine applications such as boats and yachts (12.8 V DC systems)
• Recreational vehicles (RVs) and camper electrical systems
• Backup power for telecom, security or small UPS systems
• Portable power packs and inverter-based household backup

When it may not be suitable

This battery may not be appropriate for systems that require voltages substantially different from 12.8 V without additional converters or for applications that demand very high short‑term surge currents beyond its 200 A continuous rating. It is also not a drop‑in replacement for specialized lead‑acid charging systems unless the charger settings are compatible with LiFePO4 charge profiles or a proper LiFePO4 charger/regulator is used.

Key specifications

• Nominal voltage: 12.8 V
• Capacity: 200 Ah (nominal)
• Continuous current rating: 200 A
• Chemistry: Lithium Iron Phosphate (LiFePO4)
• Integrated battery management system (BMS) with protections for overcharge, over‑discharge, short circuit and temperature
• Bluetooth monitoring for state of charge, voltage, current and fault reporting

How to use

Install the battery in a dry, ventilated location with adequate clearance for wiring and monitoring. Connect to a compatible DC system or inverter using appropriately sized cables and terminals to handle the continuous current rating. Configure your solar charge controller or charger to a LiFePO4 charging profile (recommended charge voltage and cut‑off settings per Volt documentation) and enable Bluetooth monitoring via the manufacturer’s app to view state of charge, voltage, current and alarms. Observe the BMS indicators and app notifications for any fault conditions and follow standard safety practices when wiring, charging and maintaining the battery.

What to consider before purchase

• Ensure your charger or solar regulator supports LiFePO4 charge profiles or can be programmed accordingly
• Verify that cable sizes, fuse and breaker ratings are appropriate for 200 A continuous current
• Confirm physical dimensions and mounting options fit your installation space
• Check required operating temperature range for your application environment

Usage recommendations

For reliable long‑term performance, use a charge controller with LiFePO4 settings, avoid deep discharges below recommended cut‑off, keep the battery within the specified temperature range during charge and discharge, and monitor status regularly via Bluetooth to detect and address issues early.
