We often get asked what battery do we run in our track cars that also need to run on the road or even daily! We have tested multiple big brand battery companies and have a clear winner!
 
JWM Batteries are a class above the rest without the silly price tag. We have been running this exact battery for the last 12 months on our road/track car without a single hiccup!
 
This is a package kit which includes the lithium battery, lithium battery charger and lightweight battery bracket for easy mounting! We have used this bracket to bolt it down to the stock location to keep within time attack regulations, weighin in at just 2kg!!!

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.

Be aware the digital display should be switched off when not in use to prevent battery discharge
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.
