Ideal Applications & Compatibility

This high-performance battery is particularly well-suited for:

• High-Power Electric Bike Conversions (DIY Projects requiring maximum energy)
• Performance Electric Mountain Bikes (eMTB) tackling challenging terrain
• Electric Fat Bikes and Cargo E-bikes needing extended operational range
• Riders seeking maximum power output and minimized voltage sag under load
•  

Compatibility Checklist:

Please verify the following carefully before purchasing:

• Frame Fit: Crucially, measure the internal space of your bike's frame triangle (length of each side, available depth/width). Compare these measurements with the battery dimensions (approx. 395x255x355x75mm - subject to slight variation). Ensure sufficient clearance for the battery itself, mounting straps/brackets, and cable routing without interference.
• Voltage Matching: Select a battery voltage (48V, 52V, 72V) that EXACTLY matches your e-bike's motor and controller rated voltage. Using mismatched voltages will cause component damage and potential safety hazards.
• Power Requirements: Ensure the battery's Continuous Discharge Current capability (Rated 1C, Max 5C) meets or exceeds the peak and continuous power demands of your specific motor and controller combination. Consult your motor/controller documentation if unsure.
• Mounting Method: Triangle batteries are typically secured using heavy-duty Velcro straps or custom-made brackets bolted to frame bosses (if available). Confirm how you intend to mount it and whether mounting hardware is included or needs to be sourced separately.
• Connectors: Check the battery's discharge connector type (e.g., XT60, XT90, Anderson Powerpole - specify which connector is standard or available) and ensure it is compatible with your controller's input connector, or obtain a suitable, high-quality adapter rated for the expected current.

Installation & Care

Installation Guidance:

• Carefully position the battery within the frame triangle, ensuring optimal weight distribution and avoiding interference with pedals, cranks, or suspension components.
• Secure the battery firmly using appropriate high-strength straps or mounting hardware. It must not shift, vibrate excessively, or rub against the frame during riding.
• Connect the main discharge cable to your controller, paying strict attention to correct polarity (+ positive to +, - negative to -). Reverse polarity will cause severe damage.
• Neatly route and secure all cables, protecting them from pinching, abrasion, or snagging.
• Professional installation is strongly recommended if you are unfamiliar with e-bike electrical systems and wiring practices.
•  

Essential Battery Care for Longevity:

• Charger Compatibility: ONLY use the charger specifically designed for this battery's voltage (48V/52V/72V) and Li-ion chemistry. Using an incorrect charger is extremely dangerous and will damage the battery voiding the warranty.

• Charging Practices: Charge in a cool, dry, well-ventilated area on a non-flammable surface. Avoid charging immediately after heavy use (allow the battery to cool). Do not leave charging unattended, especially overnight. Disconnect once fully charged.
• Temperature Management: Operate, charge, and store the battery within recommended temperature ranges (typically 0°C to 45°C for charging, -20°C to 60°C for discharging/storage - consult specific datasheet if available). Avoid prolonged exposure to direct sunlight or freezing temperatures.
• Storage Protocol: For storage longer than one month, discharge or charge the battery to approximately 40-60% state of charge. Store it in a cool, dry place disconnected from the bike. Check the voltage every 2-3 months and top up if necessary.
• Discharge Habits: Avoid completely draining the battery whenever possible. Frequent deep discharges can shorten its overall lifespan. Recharge it after use, ideally before it drops below 20% capacity.
• Physical Protection: Keep the battery casing clean and dry. Protect it from significant impacts, drops, punctures, and submersion in water. Regularly inspect connectors for cleanliness and integrity.
