Expert Car Tune Up Services in Portsmouth

Our product range goes from 1200 PCA (Pulse Cranking Amps), down to 25 PCA, depending on the application. If properly selected, our batteries will deliver more current than the lead acid battery you're replacing, and so your motor will start faster and more reliably.

When engine designers decide which battery they need to start an engine, they work out how many Cold Cranking Amps (CCA) are required. Amp Hours (Ah) are a by-product of the CCA of a battery - the more CCA you need, the more Ah you get. The Lithium technology we use is more energetic, and lithium is much lighter than lead, so can produce more current from a lighter amount of material than you could with Lead Acid. So you get the same PCA with fewer Ah, and the battery is smaller and lighter. Similarly, the LightweightLead Technology uses the most concentrated lead acid technology available, maximising reactive surface area and hence cranking power for the minimum weight.

Racing Batteries contain no liquids, so they are happy in any orientation - sideways or even upside down. Just keep them away from the exhaust - 80 degrees centigrade is as hot as they like to get. Racing Batteries are fairly tough, but don't mount them directly in contact with the engine - a bit of vibration isolation and distance from heat sources is a good idea.

If your engine is tuned you may need a bigger battery - particularly if you are running higher compression or greater capacity than standard. Let us know your engine spec and we'll do our best help you decide on the right battery for you.

Racing Batteries are not fitted with a BMS (Battery Management System) for one simple reason - they don't need one. Previous lithium technologies (particularly lithium polymer) needed a BMS to prevent overcharging and maintain cell balance. LiFeP04 doesn't need these features in a starter battery application - the chemistry itself is proof against these issues. Other LiFePO4 battery manufacturers claim to have a BMS fitted, but even when they do they dont work for 2 main reasons: - to do cell balancing (which you don't need) you need a multi pin charger (one pin for each cell), but when it's charging from your vehicles alternator the battery only has a + and - terminal, so it can't balance charge. - a built in low voltage cut-off (which would be the most useful feature of a BMS) that can flow 200+ amps would be prohibitively expensive, big and heavy, adding a lot of cost and weight to a Racing Battery. The M2Power capacity batteries we carry have a high quality fully featured BMS, but because of this they are unable to supply enough current to start an engine.
