12V 300Ah Essential Series – Bluetooth & Heated LiFePO4 Battery

High-capacity 12V power with cold-weather charging and simple monitoring built in.
The 12V 300Ah Essential Series battery is designed for users who want long runtime, strong current capability, and dependable everyday operation—without adding complexity to the system. Built on stable LiFePO4 chemistry, it combines internal heating for sub-zero charging, Bluetooth monitoring for quick status checks, and an advanced smart BMS to protect the battery through real-world charging, discharge, and temperature swings.

With IP54 weather resistance and a maintenance-free design rated for 4,000+ cycles, it’s a practical choice for larger 12V banks supporting inverters, electronics, lighting, pumps, and other continuous loads where reliability matters.

Overview

• IP54 weather-resistant design
• Bluetooth monitoring with iOS and Android support
• 4,000+ cycle life
• Advanced smart BMS
• Internal heating for sub-zero charging
• Safe, reliable, maintenance-free operation

Built for Long Runtime and Heavy Loads

With 300Ah of capacity, this battery is built to run longer between charges and provide stable output under sustained demand. It supports 200A continuous charge and discharge, plus 400A peak discharge for short bursts—useful for brief load spikes where extra current is needed without sacrificing overall system stability.

Bluetooth Monitoring for Everyday Visibility

Integrated Bluetooth works with iOS and Android apps, allowing you to check key battery information without installing external meters. This is especially helpful when the battery is mounted in compartments or equipment bays—quick checks and alerts can be viewed from your device for easier day-to-day management.

Internal Heating for Sub-Zero Charging

Cold temperatures can restrict lithium charging, but this model includes internal heating designed to support charging down to -20°C (-4°F). When conditions drop, heating helps bring the battery into an acceptable charging range so your system can remain usable through colder seasons rather than being limited by temperature.

Advanced BMS Protection

The built-in smart BMS monitors operating conditions and helps protect the battery and connected equipment. Protection features include:

• Overcharge and over-discharge protection
• Over-current and short-circuit protection
• High- and low-temperature disconnects

These safeguards help reduce the chance of battery stress during variable loads, charging sources, and environmental changes.

Scalable System Options

• Up to (4) batteries in series (up to 48V)
• Up to (4) batteries in parallel (up to 1,200Ah)

This provides flexibility to build larger systems over time while staying within designed configuration limits.

Specifications

Description

The 12V 300Ah Essential Series battery uses LiFePO4 chemistry to deliver stable deep-cycle power for high-demand 12V systems. Internal heating supports charging in sub-zero conditions, while Bluetooth connectivity works with iOS and Android apps for convenient monitoring. An advanced built-in smart BMS provides overcharge/over-discharge protection, over-current and short-circuit protection, and high/low temperature disconnects. Designed for expansion, it supports up to four batteries in series (up to 48V) and up to four batteries in parallel (up to 1,200Ah). With 4,000+ cycles and a maintenance-free design, it’s backed by an 11-year manufacturer warranty.
