- 36V and 48V available: Compatible with BBS01 (36V), BBS02 (36V/48V), BBSHD (48V), and Bafang hub motors across both voltage standards.
- High capacity options: Available in capacities from 10Ah to 20Ah, allowing range to be matched precisely to your commute or touring needs.
- Integrated BMS protection: The built-in Battery Management System guards against overcharge, deep discharge, short circuits, and thermal issues for maximum cell longevity.
Frequently Asked Questions About the BAFANG RACK Battery
How is the BAFANG RACK battery mounted on the bike?
The RACK battery slides onto a compatible rear carrier rack (often included or sold separately) and locks in place with a key. The power cable then connects to the motor or controller. The carrier must be rated to support the battery’s weight and be firmly attached to the frame for safe operation.
How much range does a BAFANG RACK battery provide?
A 36V 17.5Ah RACK battery typically delivers between 80 and 130 km on moderate assist on flat terrain. In hilly conditions or on maximum assist, expect 40 to 70 km. A 48V battery of equivalent capacity will generally yield slightly more range due to its higher energy density.
Is the BAFANG RACK battery compatible with all Bafang motors?
Yes, the RACK battery is compatible with BBS01, BBS02, BBSHD, HR, and HF motors when the correct voltage is matched (36V or 48V). Always confirm the voltage requirement of your motor before ordering a battery, as mixing voltages can damage the motor controller.
How should I store the BAFANG RACK battery long-term?
For long-term storage (several weeks or more), charge the battery to approximately 50% and store it in a cool, dry location between 10°C and 25°C. Avoid leaving a lithium battery fully charged or fully discharged during extended storage, as both extremes reduce long-term capacity.
Compare with the TUBE battery for a more discreet look, or the INTUBE battery for premium integration. See compatible motors in our BBS02 guide.
Frequently Asked Questions about the rack rack Battery
What capacity is recommended for the rack?
For daily commuters, 10–14 Ah (360–672 Wh) at 48 V is usually sufficient (range: 40–80 km). Touring cyclists and e-MTB riders benefit from 15–20 Ah (720–960 Wh) for full day rides over 100 km. Larger capacities increase weight and should be matched to actual usage requirements.
How do I mount the rack battery on my eBike?
The rack battery is secured to the frame or rack using the supplied mounting hardware. Ensure a firm fit and confirm the lock has engaged before connecting the cable. Never connect the cable before the battery is fully seated in its mount.
How long does the rack battery take to fully charge?
With a standard 2 A charger, a 14 Ah battery takes approximately 7 hours for a full charge. A faster 5 A charger reduces this to around 3 hours. It is recommended to complete the final 20% of charging with the standard charger to protect cell longevity.
