E-Bike Battery Guide: Cells, Capacity, Range and Cycle Life
What importers should check before signing a battery specification — cell grades, BMS design, cycle-life claims and warranty maths.
Battery specifications decide an e-bike's reputation more than any other component. This guide walks through what the numbers on a spec sheet actually mean — and which ones your supplier should be able to prove with test reports.
Key Features
Cell grades: A-grade vs "A-minus" cells and why matching matters
Capacity vs usable energy: 36V 15Ah is not 100 km on every route
Cycle life claims: 80% DOD at 25°C is the industry reference — ask for the chart
BMS essentials: balancing, temperature cut-off, over-discharge protection
Warranty maths: 2-year battery warranty vs realistic 3-year fleet duty
