Product FAQ
What electric vehicles is the 48V 40Ah battery pack suitable for?
It is built for 48 V platforms: e-bikes, e-scooters and light electric vehicles. At 48 V nominal and 40 Ah it stores 1.92 kWh and supplies 80 A continuous, which covers mid-power hub and mid-drive drivetrains as well as light four-wheel platforms.
Can the 48V 40Ah pack be customised for OEM and ODM projects?
Yes. Shell dimensions, output connector, BMS parameters and rated capacity can be configured for OEM and ODM orders. Send your target voltage, capacity, continuous current and enclosure envelope and we will confirm the matching configuration and lead time.
How is the 48V 40Ah battery pack shipped?
The pack is classed as Class 9 dangerous goods for transport, so it ships as UN38.3 tested lithium batteries with a UN38.3 test report and MSDS available on request. Air, sea and rail routing options depend on destination and order volume – confirm at the quotation stage.
