The battery is an essential part of the electric bikes. Battery supply power to drive the motor. Without the battery, electric bikes are worse than regular bicycles. The electric bike is more substantial than a regular bicycle. The rider has to pedal the electric bike to the nearest location for recharging the battery. How to keep the battery healthy is very important to all passengers.
Very often, we hear from our electric bike user complaint his battery is weaker. But bike riding is fun and enjoyable. I think we should look into more details about battery type and how to keep in good condition.
A. Types of Lithium Battery:
- Lithium-ion (Li-pol) batteries – This model is the most use at electric bikes by electric bikes fabricators. It appears excellent performance in range, weight, and price. It’s the best feature with the absence of free liquid. No need to have a hardcover for protection, making it lightweight. It can easily mold into many different shapes.
- Lithium Cobalt (LCO) batteries – It claims can contain high energy in a smaller dimension. In the market, it is a compact, lighter, and robust package.
- Car manufacturers chose lithium Manganese (LiMg2O4) batteries – This model for patent use by the hybrid car called Nissan Leaf. It is the best battery performer, more powerful, last longer, but the price is high.
All models are useable and used by electric bikes fabricators. They are interchangeable, provided they can fix it the same battery location of electric bikes and having the same type of power connectors.
B. How to keep well the electric bike battery?
- A new battery supposed should last more than five years. If we have to recharge battery twice per week, the cycle of recharging the battery is (52 x 3 x 5) = 780 cycle. In the market, most Lithium battery has a minimum period of 800 to 1000.
- Keep the battery fully charged before every riding to ensure the battery has every top performance.
- Do not wait until the battery is flat for recharging. You can restore the battery after each riding.
- If electric bike idles for one week, take out the battery for recharging at least twice per week.
- Take out the battery before start using the hydro jet to clean the electric bike.
- Take out the battery if the electric bike is hanging outside the car for going to a remote location. When raining, with the speed of the vehicle, the rainwater is like pressure wash to the battery.
- Always keep the battery away from heat; the battery will decrease its electrical resistance and discharging faster, thus reducing the performance.
C. Understand the operations of the electric bike related to batteries:
- If you buy Class 1 electric bike, the motor assist when the rider pedaling when the bike speed reaches 20 mph, the engine will cease automatically. Motor halt is not due to the battery not powerful.
- If you buy Class 2 electric bike, the low-speed throttle drives the propulsion regardless of pedaling or not; the bikes speed cannot go higher than 20 mph due to the design setting. The throttle cannot go higher rate is not because the battery is not compelling.
- If you buy Class 3 electric bike, which speeds pedal-assisted electric bikes when bike speed reached 28 mph, the throttle ceases assisting, is not the battery is weak. But rider pedaling harder can reach a higher rate. Normally class 3 electric bike installed with the speedometer.
- If you choose 100% motor assistance in riding your electric bikes, the range is 22 to 30 miles depending on battery size, wind, hills, and rider’s weight.
- If you choose pedal-assist to ride the electric bike, the range can increase up to 50 to 70 miles depends on downhill, wind, and rider’s weight.
- Some electric bikes can recharge the battery when going downhill or brakes but very minimum.
- The cost of recharging the battery is minimal, about 4 to 5 cents per charge.
- Each charging of battery needs 400 to 600 watts depending on battery size and usage.
- High power motor helps in speed and climbing steepest slope. 250W electric bike can climb any steep hill with ease.
- The high capacity battery helps in a long travel range.
D. Battery models based on installation location:
MODEL #2 Hailong-S004-e-bike-battery – 36V 10 Ah bike battery
MODEL #3 Hailong S039-3 e-bike battery
MODEL #4 S002-2 Water Bottle e-bike battery
MODEL #5 Triangle Type e-bike battery
MODEL #6 Frog type e-bike battery
E. Something to learn:
- BIKE Battery A: 10Ah x 36v = 360Wh
- BIKE Battery B: 5Ah x 72v = 360Wh
- Both bikes A and B have the same capacity battery.
- Bike Battery A has higher storage of energy.
- Bike Battery B has higher voltage systems used for faster power delivery for quicker acceleration rather than efficient cruising.
- When batteries have the same capacity, choose the lower voltage system.
- High-quality battery cost more, but they maintain steady output throughout the entire discharge cycle.
- The concept is the same with e-bikes…look for bikes using high-quality battery/electronic brands for best performance and most extended life.
