Is it really twice as powerful?

You betcha! Here at Black Oak Lithium, we engineer our batteries using lithium iron phosphate technology, and it's a game-changer. Picture this – 60% less weight, a charging speed up to 5 times faster, and a significantly longer lifespan (we're talking 5-10 years longer on average). But here's the real kicker – the flat voltage curve. Unlike those lead acid batteries that start sagging as you use them, our Black Oak Lithium battery maintains a steady voltage for 99% of its charge. That means you're getting all that power down to the last drop and doubling the usable power compared to traditional batteries.

Are these lithium batteries safe?

Absolutely, positively safe and reliable! Our special sauce is Lithium Iron Phosphate (LiFePO4) – no rare earth elements, no heavy metals, and definitely no lead or acid. It's non-toxic, non-corrosive, doesn't off-gas, and requires zero watering or maintenance. Plus, it plays nice in any orientation. And here's the kicker – it won't explode or catch fire. Each Dakota Lithium battery is equipped with a battery management system (BMS) microchip, protecting it from overheating, overcharging, and short-circuiting. We even put it in a rugged, fireproof, and IP67 waterproof case for good measure.

How do I charge this battery up?

Our 12V Lithium battery prefers to be charged with our 12V Lithium Battery Charger.
