Mega-life Batteries MR-4

The Mega-life Batteries MR-4 is a Racing Battery suitable for go-karts. Please note this model does not have a reserve cell.

The ‘LiFe’ in MEGALiFe batteries refers to the Lithium Iron Phosphate (LiFePO4) chemistry used. LiFePO4 or LFP batteries retain all the regular benefits of lithium ion batteries but are significantly safer and are not prone to the overheating and explosive issues found in other chemistries (LIPO or lithium polymer chemistry found in mobile phones, RC cars, etc). This chemistry allows for charge/discharge rates up to 10x that of lead acid chemistry (including AGM, Gel, flooded, sealed, etc). Other benefits include full depth of discharge capability, 1/3 the weight and up to 5 times the cycle life of conventional lead acid.

MEGALiFe’s proprietary casing system that surpasses industry standard 10m drop test and 3m submersion testing (IPX8). A sealed, shock proof, waterproof, temperature resistant power source provides unlimited mounting options and direct replacement for thousands of applications.

But enough is never enough! MEGALiFe batteries have an integrated battery management system (IBMS) with unique features to add to the already superior performance. Overcharge voltage, short circuit, over discharge and over temperature internal protection circuits add to the already safe LiFePO4 chemistry. The IBMS also handles the industry leading ‘Emergency Starting’ reserve cell technology that allows MEGALiFe Battery to isolate the battery if flattened and restart the vehicle at the push of a button!
