Freedom Won 20kWh Lite Home 20/16 LiFePO4 Battery N-1
Product Details
Brand: Freedom Won
Weight: 199.00 kg
Freedom Lite Home 20/16 LiFePO4 Battery
- This battery is compatible with most inverters on the market
- 10-year local manufacturer’s warranty
- Support high discharge and charge power
- Batteries can be charged in shorter time due to high charge capability
Freedom Won’s LiTE technology incorporates the highest quality LiFePO4 cells with an advanced battery management system (BMS) and protection features, ensuring an ultra-safe battery with high power capabilities.
Highlights
Freedom Lite Home 20/16 LiFePO4 Battery
- High energy density: more energy less weight.
- High charge currents (Shortens the charge period – essential for a proper solar power system).
- 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 lead acid battery).
- High efficiency between charging and discharging (Very little energy loss due to heat development).
- Higher continuous power available.
Features
Freedom Lite Home 20/16 LiFePO4 Battery
- A lead acid battery can fail prematurely due to sulphating 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 kept fully charged, has a wide operating temperature range and excellent cycling performance. They are therefore good for very demanding applications.
- The typical “round trip” 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 >96%. The Final C20% charge for a lead acid battery is particularly inefficient with inefficiencies of ~ 50% and can take a very long time for the battery to become completely charged. In contrast a LiFePO4 battery will always achieve 96% efficiency and so can be fully charged more quickly while wasting less energy.
- LiFePO4 batteries save up to 70% in space and 70% in weight compared to lead acid.
- It is vital that an advance 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.
- It is also important for the battery to be able to communicate with the rest of the system.

Essential Accessories
Freedom Lite Home 20/16 LiFePO4 Battery
- Note that for connecting the battery to a PC a USB “printer” cable is required (one is supplied with each battery) CAN Bus Termination Resistor – one required per battery (one included with battery) CAN Bus Cable (RJ45 LAN Cable)-one required per battery (not supplied with battery).
- Note some inverters will require a special (non-standard pin configuration) cable – see installation manual.
