Lithium Iron Phosphate (Lite Home) batteries have several advantages over conventional lead-acid batteries:

High energy density: more energy with less weight High charge currents (shortens the charge period) High discharge currents (enabling for example electrical cooking on a small battery bank) Long battery life (up to six times the battery life of a conventional battery) High efficiency between charging and discharging (very little energy loss due to heat development) Higher continuous power available



A lead-acid battery can fail prematurely due to sulphation if it is left partially charged, fully discharged, or rarely fully charged for long periods of time. A Lithium Iron Phosphate battery does not need to be fully charged, has a wide operating temperature range and excellent cycling performance. They are therefore the battery for very demanding applications.


The typical energy efficiency (energy that can be taken out of the battery compared to energy required to re-charge) for lead acid batteries is ~ 70%. For a LifePO4 battery it is ~ 92% The final 20% charge for a lead-acid battery is particularly inefficient with efficiencies of ~ 50% and can take a very long time for the battery to become completely charged. In contrast a LifePO4 battery can still achieve 92% efficiency and so can be fully charged more quickly and using less energy.

Size & Weight

LifePO4 batteries save up to 70% in space and 70% in weight compared to lead-acid.


Lithium Iron Phosphate batteries are expensive when compared to lead-acid, but this is compensated for by longer life, size or weight considerations, superior reliability & efficiency.

Battery Management System

It is vital that the correct battery management system (BMS) is used to control the battery charging. This is important to actively balance the individual cells that make up the battery and prevent under or over voltage which can otherwise destroy the battery.
