Product Description
Unleash the full potential of your motor! This 52V 20Ah Hailong Battery is built for enthusiasts who want more speed and torque than a standard 48V pack can offer. Perfect for Bafang BBSHD, BBS02, and Tongsheng conversions.
⚡ Why Upgrade to 52V (14S)?
A fully charged 48V battery is 54.6V, but a fully charged 52V battery is 58.8V.
- Higher Speed: Higher voltage means higher motor RPM (Top Speed).
- Less Sag: The LG 21700 cells and 45A BMS ensure the power stays strong even when climbing steep hills.
🛠 Universal "Hailong" Fitment
This is the classic "Downtube" battery. It mounts to the water bottle holes on your frame.
- DIY Friendly: Compatible with 90% of mountain bikes and hybrids.
- Dimensions: 365mm (L) x 90mm (W) x 127mm (H). (Please check your frame triangle space).
⚠️ IMPORTANT: 4-Pin Mount
Please check the photos! This battery uses a 4-Pin Discharge Base.
(Many Hailong batteries are 5-Pin. This one is 4-Pin. We include the matching base plate and keys, so you can replace your old base if needed.)
