Tracer 12V 40Ah LiFePO4 Battery Module

These battery modules are for bespoke applications, ideal for fitting to customers designed equipment.
The batteries use prismatic cells that create the lightest weight construction.

Fuel Gauge

With the Tracer fuel gauge you can check the power level remaining in the battery. A touch of the button shows how much energy remains and whether you need to recharge.

Bare Ends

Tracer LiFePO4 Battery Modules are supplied with two bare-end wires; one red (+ive) and one black (-ive). These wires are to be used for charging and discharging the battery.

Lighter. Smaller. Better.

Just ⅓ of the weight of a traditional sealed lead acid battery, our super-deep discharge LiFePO4 Batteries have been designed for many applications.


Universal Connections Available

A selection of different connections are available to suit your application.

Chargers are NOT included.

All chargers require the additional:
Neutrik Socket > Terminal Block Connector (TR8158).


Safety Features

Integrated Electronic Battery Management System (BMS) provides the following protection:

  • Overcharge & over-discharge protection
  • Thermal protection
  • Over current protection
  • Short circuit protection


Flat Discharge

LiFePO4 technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance.
