Lighter Weight/Higher Energy Density
Our battery weigh is about 70% lighter than lead batteries. A typically 48V golf cart will have around 500-600 lbs. of lead acid batteries. Switching to lithium will remove over 300 lbs. out of the cart. This will reduce the amount of energy required to get your cart up to speed and will help reduce wear and tear on your carts controller, motor, suspension, frame and tires.
Our battery hold a higher voltage during use than lead batteries. This equals more torque for your motor and allows the controller and electronics to run at their optimal efficiency. When you step on the pedal with lead batteries, the voltage can drop below 10V causing the controller to run inefficiently and providing less power to the motor which reduces torque. The higher voltage of our golf cart batteries will allow your cart to get up to speed quicker, and hold the speed higher, throughout the entire charge cycle and while going up hills.
OUR batteries are 99.1% efficient whereas lead acid batteries can be as little as 50 - 80% efficient. When you charge lead acid batteries, you can lose anywhere from 10% - 50% of the energy from the charger to your batteries. This means 50% of the power used to charge your golf cart is being lost due to resistance from the lead batteries. Using your existing charger, lithium batteries can charge up to 50% faster. We recommends you purchase one of our chargers for your golf cart to get the best performance and longest life from our lithium golf cart batteries. OUR lithium batteries may be recharged in less than 1 hour when you purchase a high-speed lithium charger from us.
Our lithium golf cart batteries are designed to allow you to safely use 100% of the rated capacity without lowering the life expectancy. Lead acid batteries are only recommended to be drained 50%. Imagine filling up your gas tank with 100 gallons of gas and the car only being able to use 50 gallons before needing to refuel.
Life Time Warranty
We provides a Limited Life time warranty to protect your investment in our products. With a life expectancy of up to 5000 cycles, you may never have to replace the batteries in your cart again. Even if you used the cart every day draining the batteries 100%, you could expect more than 10 years out of the batteries - 365 days per year X 10 years is 3,650 cycles.
