LiFePO4 HD Series Professional for high current (160Amp Continuous BMS) Lithium Battery 12V 300Ah

LiFePO4 Lithium Battery: An Efficient Investment

Would you like a modern battery solution with high performance as an alternative to conventional AGM or lead acid batteries? Our range of lithium iron phosphate batteries, which come in 12v 100ah, 12v 200ah, right up to 12v 300ah rated capacity provide greater value for money due to their long-lasting and energy efficient nature.

For heavier duty usage and extreme current handling  we would recommend this 12v 300Ah LiFePO4 (160Amp continuous BMS) version - this particular 12v battery will allow you to run more power hungry equipment than the std 100Amp BMS.  You can unlock your true potential for adventure, with a continuous current handling of upto 1.9KW per battery in a parallel connection.   Our LiFePO4 solution saves over 90Kg  in weight of ‘dead lead’ compared to lead acid/ AGM batteries that would provide a similar amount of usable energy.

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.*
