In our modern world, lithium batteries have now become a fixed part of everyday life. High power, low weight, minimum memory effect, zero maintenance and low self-discharge rates are just a few of the advantages of lithium battery technology. From mobile phones to electric cars, lithium batteries and now industry standard for electrical energy storage. Here at MEGA-liFe, we hold product compliance with EU RoHS Directive, CE certification mark and certification in the US FCC. All products adhere to UN38.3 safety and transport requirements. Safe, reliable and environmentally friendly products that significantly outperform current battery technology. With different configurations to suit racing applications from kart, bike, tarmac, off road, marine and more, MEGA-LiFe has a battery for almost all racing needs. A 3-year manufacture full replacement warranty is further proof of our confidence in the outstanding product.

IBMS -Integrate Battery Management System MEGA-LiFe batteries have an integrated battery management system (IBMS) with unique features to add to the already superior performance. Cell balancing, overcharge voltage, short circuit, over discharge and over temperature internal protection circuits add to the already safe LiFeP04 chemistry. Selected models also include the industry leading, emergency start feature to add to the versatile and unique features of this line of products.

LifeP04 - Ultimate Safety, No Acid, No Risk The' Life' in MEGA-LiFe batteries refers to the Lithium Iron Phosphate (LiFeP04) chemistry used. LiFeP04 or LFP batteries retain all the benefits of any lithium battery 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 for example) . This chemistry allows for charge/discharge rates up to !Ox that of lead acid chemistry (including AGM, Gel, flooded, sealed, etc). Benefits also include full depth of discharge capability, up to 1/3 the weight and 5 times the cycle life of conventional lead acid!

LiFe 101:

Can I use a conventional car battery charger with these?

No, with an LiFe battery you can use any Lithium Ion charger - even ones for RC cars. But if you’re looking for something dedicated to then check out these Optimize chargers. 


My LiFe battery is totally flat, how can I charge these?

Please note:

It is bad to let a LiFe go completely flat and this can cause damage to the battery so please find out what is draining it and disconnect when not in use.

In some instances these batteries need ‘jump starting’, meaning you’ll need to disconnect and reconnect the charger to get it into a charging state. Once its charging just let it do what it needs to do until its full. A good charger will indicate when the battery is fully charged.

I’m not going to use this battery for a while, how can I store it?

Simple! Charge to around 40% then disconnect and remove your terminals, then store your battery as you would with any other. With no draw this should minimise any potential discharge.

MegaLife batteries are compliant with MSA championships via the applicants request.
