❓ Frequently Asked Questions
Q: How long will this battery last per charge?
A: With a 500W motor, expect 20-40 miles (32-64 km) depending on terrain, rider weight, assist level, and riding style. The 672Wh capacity provides significantly more range than standard 10.4Ah or 12.8Ah batteries.
Q: Will this work with my original Rad Power charger?
A: Yes, if you have a standard 48V lithium charger. However, we include a 2A charger in the box for your convenience.
Q: Is installation difficult?
A: Not at all. This is a direct replacement—simply remove your old battery, slide this one into the mounting base, lock it, and connect the 5-pin plug. No wiring, no modifications.
Q: How do I know when to recharge?
A: The built-in LED display shows remaining power at a glance. 4 green lights = 75-100%, 3 lights = 50-75%, 2 lights = 25-50%, 1 light = below 25% (time to recharge).
