12V 300CCA 5Ah Starter Battery – PowerStart® PS5002

The 12V 300CCA 5Ah PowerStart® PS5002 lithium Starter Battery is a very lightweight and compact product. It uses high-performance cells with Lithium Iron Phosphate LiFe (LiFePO4) delivering extreme powers. They are ideal for your motorcycles, trucks, construction equipment, airplanes, LSA, quads, jetski and other applications. A charging status LED display is located on the top of the battery. It allows you to know the estimated state of charge of the Lithium 12V 300CCA starter battery.

Compared to lead-acid batteries, PowerStart® PS5002 starter batteries offer:

  • high charge/discharge currents,
  • 80% weight gain,
  • Extreme starting power and a large pulsed discharge power reserve,
  • Optimum safety and a longer service life of about 10 years thanks to its lithium-iron phosphate technology and integrated BMS system.

Direct replacement of the lead-acid battery

The Lithium 12V 300CCA PowerStart® PS5002 starter battery has been designed to replace lead starter batteries. They can be used for competition vehicles and applications requiring very high currents.

For an efficient and powerful start

The Lithium 12V 300CCA PowerStart® PS5002 starter battery is a compact product using Lithium ion cells. It delivers very strong currents to easily start internal combustion engines. Unlike lead-acid batteries, the voltage of the PowerStart® battery drops slightly during start-up. This delivers constant power to the starter motor.


The Lithium 12V 300CCA PowerStart® PS5002 starter battery incorporates an innovative control system (BMS Battery Management System) to ensure a very high level of safety during use. The BMS constantly monitors and balances the battery cells. This is to protect it and preserve its lifespan.
The battery is protected by a waterproof ABS case. It is splash-proof and dustproof (IP56 protection class).

Our Lithium 12V 300CCA lithium starter batteries are therefore completely non-flammable!
In summary, the BMS can be used to monitor the status of individual battery elements, such as:

  • Cell tension
  • Cell temperature
  • Real-time cell balancing for optimized lifetime
  • Too high charge or discharge currents

Batteries with a better ecological footprint

PowerStart® products are lightweight, high-performance and environmentally friendly. The Lithium 12V 300CCA starter batteries directly replace older generation batteries. The latter are inefficient and harmful to the environment. This is due to the use of heavy metals and the difficulty of recycling (lead batteries VRLA, AGM, etc.).

PowerStart product is covered by a 2 years commercial warranty.
