KiloVault might be a relatively new name in lithium iron phosphate (LiFePO4) batteries, but I’d expect to hear a lot more about them based on what I’ve seen so far. The HLX+ series of batteries are well-made, drop-in-style batteries with lots of capabilities at an affordable price point. I’ll be installing a pair of the 300 amp hour batteries in my RV, but first, let’s get to know the batteries better.
