Our **52V 20Ah Triangle Battery** is designed for high-performance e-bike builds and long-range touring. By utilizing the frame's triangle space, this pack offers massive capacity and stability without compromising handling.

Premium LG 21700 Cells: Built with genuine LG 5000mAh (50L NCM) automotive-grade cells. These Grade A cells provide superior energy density and consistent power output compared to generic alternatives.

High Power Output (50A BMS): Engineered with a robust 50A continuous BMS, this battery can handle peak currents up to 100A. It is perfectly suited for high-power motors ranging from 1000W to 2500W.

Optimized Triangle Design: The 390x95x265mm dimensions are tailored to fit snugly in the central triangle of most mountain bike frames. It comes protected in a durable Blue PVC heat shrink and a heavy-duty Triangular Waterproof Tarp Bag with Velcro straps.

Extended Cycle Life: Designed for durability, this pack is rated for 1200+ deep charge and discharge cycles, ensuring years of reliable service before significant capacity degradation.

Massive 1040Wh Capacity: With over 1 kilowatt-hour of energy, riders can enjoy extended range, reducing range anxiety on long commutes or off-road adventures.

Safety is paramount when dealing with high-voltage, high-capacity lithium batteries. Our intelligent Battery Management System (BMS) provides comprehensive protection and cell management.

• Automatic Cell Balancing: The BMS actively equalizes the voltage between cell groups during charging, maximizing the pack's usable capacity and lifespan.
• Over-Current Protection: With a 100A instantaneous cutoff, the BMS protects the cells from damage during sudden power spikes while allowing for strong acceleration.
• Temperature Control: Integrated thermal sensors monitor the pack to prevent operation in unsafe temperature ranges (-20°C to 60°C).
• Short Circuit & Over-Discharge Prevention: Instant power cut-off in the event of a short circuit or if voltage drops below the critical 38.5V threshold.

The high voltage (52V) and high discharge capability (50A) make this battery the ideal power source for demanding applications:

• High-Performance E-MTBs: Perfect for off-road mountain bikes requiring high torque for steep climbs.
• Conversion Kits: Fully compatible with Bafang BBSHD, CYC X1 Pro, and other high-power mid-drive or hub motor kits (1000W+).
• Long-Distance Touring: The 20Ah capacity ensures you can cover 40-80 miles (depending on terrain/speed) on a single charge.
• Cargo E-Bikes: Provides the sustained power needed for hauling heavy loads over long distances.

For this 52V triangle pack, quality control is rigorous to ensure safety and performance.

• Cell Sourcing: We strictly use original LG 21700 cells. No fakes, no re-wrapped cells.
• Aging Test: Every finished battery pack undergoes a strict aging process and full charge-discharge cycle test before shipping.
• Traceability: Strict production records are kept for every batch, ensuring accountability and easy warranty support.

 

1. Why choose a 52V battery over a 48V battery?
A 52V battery charges to 58.8V, whereas a 48V battery charges to 54.6V. This higher voltage provides better efficiency, higher top speed, and less "voltage sag" as the battery depletes, keeping your bike feeling powerful for longer.

 

2. Will this battery fit my bike frame?
This is a triangle battery sized at 390 * 95 * 265 mm. Please measure the inner triangle area of your bike frame to ensure there is enough clearance. The included bag has velcro straps for secure mounting.

 

3. What connectors does it come with?
It comes with a yellow XT90 connector for discharge (to the motor) and a 3-pin XLR connector for charging. If your motor uses an Anderson or XT60 connector, you may need an adapter.

 

4. How long does it take to charge?
With a standard 3A charger (not included unless specified), it takes approximately 7-8 hours to charge from empty to full. With a faster 5A charger, this time is reduced to about 4-5 hours.
