Typical Applications
A special bundle of our PS-09 battery with optional bundled black powder coated aluminium cage and charger. Our PS-12 battery is designed to suit a host of different lightweight track and/or racing cars. The PS-09 is a battery for those with lightweight racing cars wanting to remove every last gram of weight - applicable for lower displacement hillclimb or race cars up to around 2000cc. Typically the PS-09 is fitted to racing cars with 1000cc bike engines running in various championships (F1000, Bikesports, etc), but they are also applicable for car engined competition vehicles (with alternator) such as Locost 750, Caterham CSCUK, Mini Sevens and plenty more.
The PS-09 also serves as a direct replacement battery for modern sports/race motorcycles, providing over double the cranking power of a standard lead acid unit and saving plenty of weight too!
We are the cheapest supplier of Motorsport UK Registered LiFePO4 batteries in the UK.
UK Motorsports (MSA) Registered battery
JWM LiFePO4 Benefits:
Extremely Powerful for its size - 280 cold cranking Amps.
Rapid Recharge: Recharges far faster than a conventional battery. Retains charge when isolated for up to 2 years.
Safe: Unlike other lithium batteries, JWM batteries are internally inert, do no run warm and do not leak as they contain no liquids. You can even install them upside down!
JWM batteries are equipped with internal electronic management to protect against overcharging, over-discharging and short circuit - as required to become a MSUK Registered supplier.
JWM batteries are supplied with a 1 year return to base warranty (excludes Misuse).

Please Note: Before fitting a LiFePO4 battery of any brand you should ensure your charging system is in good order. Poor grounds in charging and internal alternator voltage regulator circuits can damage LiFePO4 batteries. Also ensure your battery is positioned sufficiently far away from very hot engine components such as exhaust manifolds. LiFePO4 batteries present different load characteristics to your vehicles electrical system when compared to gel or lead acid. For the vast majority of cars and bikes this is not a problem, but there may be a compatibility issue if your car/bike uses an old technology thyristor based rectifier. Please contact us if you need clarification.
We recommend you isolate your battery using an FIA switch or one of our isolation switch kits when not in use to avoid parasitic discharge. Be aware the digital display should be switched off when not in use to prevent battery discharge and all forms of parasitic drain should be isolated when the battery is left for long periods to avoid damage from 100% discharge which may invalidate warranty.
