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.
