BestCell LiFePO4 battery 310 Ah

   BestCell's LiFePO4 lithium-iron-phosphate battery, with aluminum-coated prismatic cells.

• The lithium-iron-phosphate battery is extremely durable, has a high current capacity and is characterized by a fast charging rate. In addition, it is a longer-lasting and lighter alternative to lead-acid batteries.
• LiFePO4 batteries maintain over 80% capacity even after 4000 charge-discharge cycles, providing many long years of service. With negligible self-discharge even after a year of inactivity, the LiFePO4 battery is fully operational.
• Very long life, relatively low weight and current parameters make lithium-iron-phosphorus batteries are used to power recreational vehicles and campers, boats and in photovoltaics, and as energy banks, supplying energy to houses using solar panels.
