Description

Product Overview

Wanex Lead-acid Replacement LiFePO4 Batteries deliver a high energy-to-weight ratio, strong discharge performance, long cycle life, and excellent thermal stability. Designed as a direct replacement for conventional lead-acid batteries, they are ideal for solar energy systems, RVs, marine applications, backup power, and off-grid energy storage.

With flexible customization options including enclosure materials, BMS functions, Bluetooth connectivity, and OEM branding, they can be tailored to meet diverse market and application requirements.

  • Advanced BMS Protection

    Built with safety-proven Grade A LiFePO4 cells and a flame-retardant ABS enclosure, each battery is equipped with an intelligent BMS (100A standard, customizable) that provides comprehensive protection against overcharge, over-discharge, overcurrent, short circuit, and over-temperature.
  • Long Service Life

    Designed for over 8,000 cycles at 80% depth of discharge (DoD), with a monthly self-discharge rate below 3.5%, ensuring reliable performance for frequent cycling and long-term energy storage.
  • Drop-in Lead-acid Replacement

    Designed to match the dimensions and terminal configuration of standard 12V lead-acid batteries, allowing easy replacement without major system modifications. Compact dimensions also make it ideal for space-constrained applications such as RVs, camper vans, marine vessels, and off-grid systems.
