Description

The AMPTRON® 12V 400Ah Lithium LiFePO4 Battery is an ideal replacement for traditional deep cycle AGM, Gel, or Flooded lead-acid systems.

With a massive 300A continuous discharge and 600A peak discharge for 10 seconds, this battery delivers reliable power for heavy-duty applications such as 4x4s, RVs, boats, solar systems, and off-grid setups. It features premium prismatic cells, an integrated Battery Management System (BMS), robust aluminium casing, and solid busbar connectors. 

Built for versatility, it may be mounted on its side, installed in tilt trays, or set upright depending on your space.

FEATURES

Built-in smart Battery Management System (BMS) for complete internal protection

Over voltage, under voltage, over current, short circuit, thermal, and reverse polarity protection

Top-end cell balancing to maintain long-term battery health

Internal thermal safety fuses and high-pressure safety vents for extra safety

Robust aluminium casing with anti-vibration durability

Can be mounted in multiple orientations

Sealed and IP65 rated for water and dust resistance

FAQ's

Q: Can this replace my AGM deep cycle battery?
A: Yes—it’s fully compatible and performs better under higher loads and deeper discharges.

Q: Do I need a specific charger?
A: To maximise life and performance, use a charger with a lithium (LiFePO4) charge profile.

Q: How many cycles will it provide?
A: Over 2000 cycles at 100% DoD, and up to 5000 cycles at 80% DoD under normal conditions.

Q: Is it safe to install on its side?
A: Yes—the aluminium case and internal design allow for horizontal or vertical installation.
