Polinovel's HD series LiFePO4 lithium batteries are constructed with the best manufacturing techniques. Each LiFePO4 battery has an internal battery management system (BMS) that protects the battery against over charge, over discharge, short circuit, and high temperature. HD series LiFePO4 battery is truly maintenance free and will last many years.

The much higher discharge capacity Size for size means you won't have to constantly use your battery chargers, as it often the case with lead acid based units, that require a constant charge source to keep them topped up and able to operate anywhere close to their maximum life expectancy of 300-500 cycles.

Polinovel high capacity LiFePO4 batteries are best used in environments that require high power and tougher operation, such as deep cycle battery applications, boats, RVs, vans, motorhomes, off-grid appliances and much more.

Li-on battery (lithium ion battery packs), specifically the LiFePO4 variety, are also known for being better for the environment, compared to their lead acid battery counterparts. Due to the reduction of CO2 plastic and toxic lead and acid components. One lithium battery for equivalent energy usage over its lifetime can replace more than 16 traditional lead acid units.*
