Is it really twice as powerful?

You betcha! Here at Black Oak Lithium, we engineer our batteries using lithium 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 batteries are non-toxic, non-corrosive, don't off-gas, and require zero watering or maintenance. Plus, they play nice in any orientation. And here's the kicker – it won't explode or catch fire. Each 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.
