The battery provides a solution to the problem of energy wasted from solar installations at night or during periods that are not sunny. The BigBattery Lithium Solar Battery is an innovative system that captures and stores electricity from the sun, stores it in lithium ion flammable cells, and supplies power to your home when you need it.

We have made them highly efficient while delivering extended life—around 4000 cycles versus 2000 for lead acid batteries. To store excess solar energy, line up a row of panels with enough space between each panel so there's no shadow on any one panel. We recommend anywhere between three to six panels minimum for optimal performance. 

The new Big Battery 12V 2.2kWh battery is designed around our NEW LiFePO4 cells, which come pre-installed with an advanced BatteryEVO BMS that will protect your cells from being damaged once they become discharged to a certain level at 24°Ffahrenheit for optimal safety and longevity of the pack.

With a 300A fuse and built-in low charging disconnects at -24oF, this Lithium Iron Phosphate electric battery has been upgraded so you can use it as a drop-in replacement for almost any Golf Cart or Off-Grid Power System application! The all-new two thousand watt hours lithium iron phosphate power block can provide nearly four times more power than standard lead acid 12v deep

For it’s size, this is the strongest 12V Power Block in the USA providing you with More Power Capacity, Shorter Charge Times and Longer Life Cycles. You’ll see and feel the difference
