Trophy Battery uses lithium iron phosphate (LiFePO4) batteries and these LiFePO4 batteries are safer than regular Li-ion batteries because they do not suffer from thermal runaway. LiFePO4 batteries have been thoroughly tested and will not catch fire even if abused. Lithium iron phosphate batteries use a limited number of battery cells. This is in contrast to similar capacity Li-ion batteries that use hundreds of Li-ion cells. A single battery cell is the heart of any battery. Invest in new, high-quality batteries from well-known brands such as EVE Power or CATL. Trophy Battery is a 48 volt battery category with a supply voltage of 51.2 volts (nominal). Each 51.2 volt Trophy battery is suitable for all 48V class inverters.
