Figure 1: The sleek triangle design of the battery fits seamlessly into most e-bike frames, blending functionality with aesthetics.
Crafted with precision, this battery features a compact triangle shape that’s engineered to fit the frame of most electric bikes – from mountain bikes to commuters and tricycles. At just 6.5kg (14.3lbs), it adds minimal weight to your ride while delivering maximum power. The robust outer casing protects the internal lithium cells from bumps, scrapes, and the elements, making it durable enough for daily use and off-road adventures alike.
This battery isn’t a one-size-fits-all solution – it’s built to adapt to your ride. Choose from 48V or 52V voltage options, and 21Ah or 28Ah capacity to match your motor’s power (compatible with 750W, 1000W, 1500W, and 2000W motors). Here’s a breakdown of the key specs:

Every battery undergoes strict QC testing (appearance and function) before shipment, so you can trust that you’re getting a product that meets high-quality standards. The use of brand-new 18650 lithium cells ensures consistent performance and long-term reliability – no old or recycled cells here.
Figure 3: The built-in 50A BMS (Battery Management System) is the unsung hero of safe riding.
The battery’s integrated 50A BMS (Battery Management System) is designed to protect you and your investment with five critical safety functions:
No more worrying about leaving your battery charging overnight or riding in extreme weather – the BMS has you covered. Plus, the power switch with LED indicator lets you check remaining battery life or charging status at a glance, so you never get stranded.

One of the most practical features of this battery is the integrated USB port. Whether you’re commuting to work, exploring trails, or running errands, you can charge your smartphone, GPS device, or other small electronics directly from your battery. No more carrying a portable charger or worrying about dead devices – stay connected wherever your ride takes you.
The LED indicator next to the power switch shows you exactly how much charge is left (e.g., green = full, yellow = half, red = low) and lights up when charging, so you’re always in the know.
Figure 5: The included 8 battery straps and base plate make installation a breeze – no technical skills needed.
Forget about complicated wiring or professional installation. This battery comes with everything you need to mount it to your e-bike’s triangle frame: a base plate and 8 heavy-duty adhesive straps. Here’s how simple it is:
Installation takes less than 10 minutes, even if you’re not mechanically inclined. The compact triangle design fits most standard e-bike frames, but be sure to confirm the battery size (365*230*395*T75mm) matches your bike’s installation space before purchasing.
Figure 6: With 1000+ charge cycles, this battery will last for years of regular use.
Most e-bike batteries last 300-500 charge cycles before their capacity drops significantly. This battery doubles that with a 1000+ cycle life – that means if you charge it once a week, it will last nearly 20 years! Even with daily charging (for commuters), it will provide reliable performance for 2-3 years. That’s exceptional value for money, saving you from frequent battery replacements.
Range anxiety is a thing of the past with this high-capacity lithium battery. The actual endurance mileage depends on factors like motor power, terrain, rider weight, and speed, but here’s a realistic estimate based on capacity and voltage:
Figure 7: Whether you’re commuting to work, exploring trails, or running errands, this battery gives you the range to go further.
For example, if you’re a daily commuter with a 750W motor and a 20km (12-mile) round trip, the 52V 21Ah model will last 3-4 days on a single charge. The 52V 28Ah model can handle a full week of commuting without recharging. For off-road riders or those who tackle hills regularly, the extra capacity ensures you won’t have to cut your adventure short.
This battery isn’t just for standard e-bikes – it’s versatile enough to power a wide range of electric vehicles and setups. Here are the top use cases:
Skip the gas station and traffic jams. This battery provides enough range for daily commutes, and the USB port lets you charge your phone on the way. The easy installation means you can switch it between bikes if needed.
Mountain bikers and trail riders need a battery that can handle rough terrain and high power demands. The durable casing and 50A BMS stand up to bumps and steep climbs, while the long续航 keeps you exploring longer.
Electric tricycles and cargo bikes require extra power to carry heavy loads. This battery’s compatibility with 2000W motors and high capacity makes it ideal for transporting goods, groceries, or passengers.
If you’re converting a standard bike to electric with a 750W-2000W conversion kit, this battery is the perfect match. It’s designed to work with most kits and comes with all the necessary connectors (XT60 plug).
Fat tire bikes are great for sand, snow, and rough terrain, but they require more power. This battery’s high discharge current (50A) and large capacity ensure smooth performance even with wide tires.
Riders with modified 36V/48V motors (250W-1000W) will appreciate the battery’s flexibility. It works with most modified setups and can be customized to match your specific voltage, capacity, or size needs.
