The stock battery only offered 30-40 minutes of runtime, so I replaced the stock lead acid battery with a new upgraded IP67 waterproof Li-ion pack rated to last for 5000+ cycles. This improves run time to 1.5 - 2.0 hours of continuous use! Brand new charger. Motor is strong. This is better than a new Hyper. Come by and check it out.
