How to Get a Range Boost for Your E-bike?
Dual e-bike battery setup types: parallel (dual battery) and power bank (range extender).
The parallel battery type: 1. With two e-bike batteries in parallel, the output voltage is as one battery, but the amp hours (range or power) are doubled. Discharged at the same time. 2. One battery power the e-bike, and automatically or manually switch to the second battery when the first one is out of power.
The range extender type: The range extender is plug-in with the main battery. When the main battery is getting low, the range extender battery can start to charge the main battery. It works as a “power bank”.

Compact and Lightweight
The electric road bike has become the new trend, but lightweight and high integration is a big challenge to battery design and production. Tritek e-bike batteries are used in BMC, Wilier, Bianchi, Cannondale, Giant, and other high-end e-bikes, especially e-road bikes.
That is why we fully understand how important weight and dimension are to remain the e-bike as light and compact as possible. Our team has rich experience in battery structure design with limited space and strict requirements for high-end bikes.
Intelligent BMS
Integrate with protocol applicable to the onboard applications, allowing you to communicate with the e-bike battery during riding. Battery Management System detects potential sources of error and protects cells from overloading.
- Full solutions customized BMS
- OTA update support
- 3-level protection for current, voltage, temperature
- Diagnose tool history & error table
- High power in small volume
- Multiple functions: 4G, Bluetooth, E-lock, USB-C, G-sensor, DC Aux modules, etc.
- Protocol CAN(Adaptable from 250k to 1MB), RS485, UART
No downtime, increase power or range.
- Simultaneous discharge increases power
- Sequential discharge extends the range.
- Hot-swappable by CAN automatic ID setting
- Our modular battery design supports both vertical and horizontal installation, enabling side or bottom removal to fit most e-bike frame designs.
- A shared battery holder accommodates both 600Wh and 800Wh configurations, reducing SKU complexity and simplifying inventory management.
- The standardized modular interface also enables future capacity upgrades without redesigning the vehicle frame.
Low Power Consumption
Low self-discharge, no over-discharge, and longer cycle life are challenges to any e-bike battery manufacturer. We design our batteries in a way that they consume less energy and have low self-discharge.
- Cell low self-discharge
- Pack low self-discharge
- Low power consumption ≤ 50μA
Great consistency:
- Deep sleep mode for storage
- Free of charge for 3 years
- Cell voltage difference ≤ 15mA
Excellent for Extreme Temperature
Constant power output with a constant voltage curve for hours even under extreme circumstances. Run safely using our e-bike battery with discharge rate ≥90% in any high or low temperatures.
- Charge temperature: 1-50℃
- Discharge temperature: -20-60℃
- Relative humidity: ~ 65%, 45-85%
Waterproof IP67
Our e-bike battery packs adopt a 3-layer waterproof protection system designed for real-world riding environments:
- Conformal-coated PCBAs prevent moisture ingress, humidity-related corrosion, and electrical short circuits.
- Pressure-equalizing breathing valves undergo 100% inspection during production to verify sealing performance while preventing internal pressure buildup.
- Structural sealing silicone is precisely applied to fully match the enclosure design, ensuring durable waterproof protection throughout the battery’s lifecycle.
