E-bike batteries can be confusing; you might see a battery described as 36 volt or 10 amp hour or 500 watt-hours. Which figures should you be looking at and what do the differing battery measurements mean for the performance of an e-bike? Here EBR demystifies the subject.
Definitions – And What They Mean for eBikes
When you are considering what battery numbers do mean it helps to have a bit of background knowledge on the three basic units of measurement you commonly see in battery descriptions.
Battery voltage can be thought of as the electrical ‘pressure’ available within the battery to push electrons around the bike’s motor system, so powering it. A common analogy is to water pressure – the ability of water pressure to push a fluid around a system being likened to the ability of a battery’s voltage to push current through a system.
