FAQ 2023


Answer: In short, NO!
3 main reasons we consider MEGALiFe a safe lithium product.

Number 1 is the type of lithium chemistry used in MEGALiFe Battery is lithium iron phosphate (LiFePO4). This is the safest of the lithium-based battery chemistries and NOT THE SAME as the battery in your cell phone or RC car (Lithium polymer or LiPO). Thermal runaway on this chemistry is roughly 275ºC.

Number 2 is the construction of the casing and internal packaging. MEGALiFe houses our LiFePO4 cells in a proprietary case that is IP67 rated and drop tested to 10m! This is achieved by a rigid ABS case being filled with an expanding type foam product that keeps the cells, wiring and internal electronics completed supported. The entire battery is glued together for the rest of the seal.

Number 3 is the internal BMS (battery management system). The internal BMS controls the potential issues seen with cells over-voltage, under-voltage, short circuit and high temperature. Our MOSFETT controlled board has you covered not only for safety but, also provides all the monitoring and measure to ensure maximum battery life.

Remember, if you pour petrol on a fire it’s dangerous but if you put it inside a correctly designed fuel tank in your car it’s safe. Lithium batteries are the same. With abuse and misuse, like thousands of other products, they can be dangerous but we've done all we can to ensure this is a long shot!

Answer: We have over 40 different case sizes to suit most cars, bikes, boats, jet skis, 4x4 and other applications. Our batteries are direct replacement style in the industry standard 'group' sizing's.

The best option is to search for you car make and model. You can also take measurements of your battery and scan through a full list of our products here. If you still can find what you’re after just drop us an email, message us on social media or give us a call and we will find it for you!

Answer : YES! We provide a 2 year, full replacement warranty on standard batteries and 2 year, full replacement on Motorsport batteries.

Due to our innovative case designs and assembly techniques, we are one of the few lithium products on the market to offer an under-bonnet warranty to 80ºC. Our batteries have external indication stickers that show whether the temperature of the battery has exceeded this limit.

Don't temps under-bonnet get higher than 80ºC you say?!

Some areas under the bonnet of some vehicles will reach more that 80ºC that is very true (next to an exhaust, an area without airflow like near a firewall etc) but most factory battery locations are in areas with good airflow (e.g. behind a headlight) and away from more severe heat sources (next to a turbo etc). One of our test units continues to run in a 79 Cruiser in western Queensland with maximum temperature of 75ºC seen at the battery. Full warranty information can be found here Our Warranty Document

Answer : Lithium chemistry gives you both!

As a starting battery, LiFePO4 chemistry gives more than 2x the CCA for the physical size and most lead acid/AGM. This means they are an excellent ‘start’ battery for a large or high compression engine. It also means, if space is tight, you can install a smaller battery for the same start power. In the case where dual batteries were used in parallel as starters (LandCruiser 79/200, Prado, early Navara, etc) a single MEGALiFe can be used for the start enabling the other space to be left for other accessories or an Aux battery.

Although the Ah numbers do not appear to be the 'same' as a lead-acid (AGM/Gel/sealed), lithium chemistry allows for 100% depth of discharge, not the regular 50-70% you see in ‘deep cycle’ lead/AGM batteries. For example, a 100Ah lead battery may have a usable capacity of 50Ah based on the manufacturer 50% DOD recommendations where as a 50Ah lithium battery has the same usable energy/Ah due to discharge capability!
