Choosing an Electric Bike Battery
Electric bikes are becoming more popular as a green and healthy means of virtually sweat-free transport. Whilst accepted in Asia they are still article of a alcove bazaar in Europe and the US partly due to array weight and the aggravation of recharging times.
With worldwide emphasis on finding more eco-friendly methods of transport however, the spotlight is back on battery-powered methods of transport so technological advances are filtering their way through the to e-bike market.
How Electric Bikes Work
Motorized electric bicycles offer power-assisted cycling, the motor being powered by a rechargeable battery. The cyclist still has to do some work especially when starting off and also on hills although the strain of hard pedaling is taken off the rider by using the motor. Lazy riders can opt to let the motor do nearly all the work but that wears the motor out more quickly and runs the battery down faster.
Main Types of Electric Bike Batteries
Sealed Lead Acid (SLA). Cheap to produce, most Electric bikes in recent years have used SLAs. They are virtually maintenance-free and have a high energy density but they are very heavy (typically 30 lb.), cannot be answerable bound and will eventually die back the array beef are old.
Nickel-Metal-Hydride (NiMH). The advantage of NiMH batteries is their adeptness to fast allegation additional they are lighter and beneath baneful than SLAs whilst advancement aerial activity density. Performance, however, is reduced in cold weather and they need to be fully discharged at set intervals to maximize battery life.
Price and weight are two key factors to accede but it is important to analyze the performance, constancy and recharging times of anniversary array afore purchase.
Many manufacturers reduce battery weight by compromising power output so it is important to read the small print carefully. A cyclist wanting to use an e-bike for regular commuting may well need to invest in a light Lithium battery with a fast recharge option to avoid having to carry a spare as back-up. Occasional cyclists, on the other hand, may be happy with a cheaper SLA battery.
