Amptron Lithium 36V 75Ah / 100A LiFePO4 battery

$2,100.00
Description

The AMPTRON® 36V 75Ah Lithium LiFePO4 Battery is a high-performance deep cycle solution designed to replace traditional Gel, AGM, or Flooded Lead Acid batteries. With a 100A continuous discharge rating and 200A peak discharge (for 3 seconds), this unit is ideal for demanding applications such as electric outboards, golf carts, and marine systems. Built using premium prismatic cells and an advanced internal Battery Management System (BMS), this battery ensures safety, stability, and long service life under harsh conditions.

AMPTRON’s integrated BMS constantly monitors and protects each cell against overcharging, over-discharging, excessive temperature, and short circuits. It also balances cells at the top end of charging to maintain long-term battery health. Additional safety features like internal thermal fuses, flame retardant electrolyte, and high-pressure safety vents provide peace of mind in extreme environments.

This battery is IP65 rated for water and dust ingress protection and can be installed on its side for flexible mounting. Whether you're upgrading your energy storage or powering high-demand systems, the AMPTRON 36V 75Ah battery delivers reliability and durability backed by a 4-year warranty.

FAQ's

Q: Can I use my lead-acid charger with this battery?
A: Only if it supports a lithium charge profile. Otherwise, we recommend upgrading to a lithium-compatible charger.

Q: Is this battery waterproof?
A: The battery is IP65 rated—protected from dust and low-pressure water jets from any direction.

Q: How long does it take to fully charge?
A: Approximately 5 hours from a low-voltage cutoff using the optimal charge current of 15A.

Q: What’s the cycle life?
A: Over 2000 full cycles at 100% DoD. Up to 5000 cycles if regularly discharged to 80% or less.
