KiloVault 1800 HLX 1800Wh 12V 150Ah Lithium Ferro Phosphate (LFP) Solar Battery | 5000 Cycles, 7.5 Yr Warranty

The KiloVault™ HLX series of solar lithium batteries was specifically designed and tested for the beating that serious hybrid and off-grid inverters and solar charge controllers can throw at it.  Compared to traditional deep cycle batteries, the HLX Series’ lithium battery technology will more efficiently store and deliver the renewable energy you have generated, with no maintenance on your part.

Deep Cycle, Up to 100% DoD

Hammer the battery with 100% discharge every day and even after 2000 cycles 80%+ of the battery’s capacity will be there for you. Discharge it less and the story gets even better.

Higher Efficiency, Less Waste

You’ll get 8 to 14% more usable stored energy compared to lead acid batteries thanks to higher efficiencies in the HLX series.

Smart Investment

HLX series has lower cost per watt-hour stored per cycle than lead acid batteries due to long cycle life and greater depth of discharge capability.
