1. Evaluate vehicle compatibility
Parameter matching: Verify the original battery voltage (48V/60V/72V). The capacity of the new battery should be no more than twice that of the original battery (for example, 60V20Ah can be upgraded to 60V40Ah).
Space measurement: Use a tape measure to measure the dimensions of the battery compartment. Lithium batteries are 50% lighter than lead-acid batteries, and their capacity can be expanded by modifying the bracket.
Device compatibility: Verify whether the controller and motor support higher voltage or capacity. The current limit of the controller must be ≥ the discharge current of the new battery (for example, a 100Ah battery requires a controller with a rated current of ≥ 50A). If necessary, please consult a professional engineer.
2. Core Component Upgrade
Built-in BMS system: Optional intelligent BMS battery with temperature monitoring function, which prevents overcharging and overdischarging and extends battery life by 30%.
Charger compatibility: Lithium batteries require dedicated chargers (for example, lithium iron phosphate batteries need a 4.2V/cell charger);
Circuit optimization: Replace with 6mm² copper wire to reduce energy loss (conductivity increased by 20%).
3. Safe Installation
Disconnect the original battery in the order of negative pole first, then positive pole.
When installing the new battery, make sure the connection is secure and take insulation protection measures to prevent short circuits.
After the upgrade, please test the operating status of the vehicle, including charging, discharging and power output.
4. Debugging and Testing
Charging test: When the battery reaches 80% of its capacity during the first charging session, stop charging to verify the automatic power-off function.
Road test verification: Ride at full load for 10 kilometers, and measure the battery temperature using an infrared thermometer (normally ≤ 45°C).
Battery range calibration: Record the distance traveled from when fully charged to when the battery level reaches 20%, and compare it with the theoretical value (an error of ±10% is acceptable).
Notes for Attention
Legality and Warranty:
There are certain restrictions on battery modifications in some areas. Before upgrading, be sure to familiarize yourself with the local regulations.
The modification may cause the original manufacturer’s warranty to become invalid. It is recommended to have it repaired at a professional repair shop.
Safety:
Do not attempt to disassemble the battery, especially the lithium-ion battery, to avoid the risk of thermal runaway or fire.
Please use a compatible charger. It is prohibited to use chargers of different specifications interchangeably.
Environmental Disposal:
Recycle used batteries to prevent pollution caused by improper disposal.
