Chargers
Gobao charging technology is built to minimize downtime through dedicated charger-and-battery compatibility. The 6 A Fast Charger handles everyday needs for standard 36 V battery systems, while the high-output 30 A Super Charger operates exclusively with 48 V Super Charging batteries to deliver an 80% charge in just 28 minutes. Super Charging batteries are fully compatible with both chargers, whereas standard batteries require the Fast Charger.
