Battery Charging Guide – Everything You Need to Know

Always confirm your REVOO e-bike’s battery type before deciding how often you should charge it. REVOO’s e-bikes come with Graphene-enhanced batteries that ensure faster charging, better heat control and a longer lifespan than conventional packs. The Graphene-powered design remains reliable under heavy use, making it perfectly suitable for daily commuting, longer trips and especially suitable for Pakistan’s hot climate.

Regular charging cycles and scheduled checks maintain performance and boost battery life, which gives you a controlled and smooth riding experience. REVOO A12 and C Series models feature an on-board Battery Management System (BMS) that displays real-time State of Charge (SOC) helping you always know how much range you have left. Read this article for complete Charging Practices.

1- Battery Charging Safety Checks

REVOO e-bikes make sure a reliable battery performance with no major issues but charging safety checks must be followed first. Graphene batteries are more durable that handle heat better and can last up to five times longer than the conventional power packs but any battery can get damaged by mishandling or exposing it to extreme heat. Proper charging habits help the battery provide steady power.

Check the battery to avoid following conditions before charging:

• Deformities

• Any Damages

• Unusual Swelling

• visible cracks

2-Necessary Steps before Battery Charging 

Follow these important steps to have safe and efficient charging;

Safe Charging Environment 

• Avoid flammable substances

• Maintain a well-ventilated area

• Keep out of direct sunlight and rain

• Make sure a flat surface to keep charger

Ensure Voltage Checks

Confirm that the charger's required input voltage (AC220V) matches with local electricity supply.

Use an Original Charger

Charge only with the recommended charger provided by the company to ensure enhanced battery performance

Charging an e-bike step by step

When you start charging:

1. Connect Charger to e-bike first

2. Connect the charger to the power socket

Note: The red light indicates charging; green light indicates completion

When finish charging:

1. Disconnect the charger from electricity.

2. Then disconnect it from the battery.

Standard Charging Time

• Standard charging time is 6-9 hours (It varies by model).

• Continuous charging should not exceed 9 hours.

• NB: Charging time depends on the battery's remaining power also.

3-Important Charging Instructions

Avoid Overcharging

Overcharging can cause excessive heat that affects battery health badly and increases safety risks. A12 and C-Series models of REVOO e-bikes come with a Smart Battery Management System (BMS) that helps regulate charging but for the previous models it’s still important not to leave your battery plugged in for so long. Charge smartly and unplug timely to keep your battery performing best.

Charge after a ride

Let the battery cool down for about 30 minutes after a long ride before charging. If your battery level is below 40–50%, giving it a charge helps maintain its long-term health.

Maintain a Regular Charging Routine

When you don't ride, you need to charge your e-bike every 2 weeks.

Do Not Let the Battery Fully Drain

Draining your battery completely can affect reducing its longevity and performance. For best results, recharge when the battery level reaches 20%–30%. It will maintain strong and stable long-term capacity of the battery.

4- Improper Charging Potential Issues

Even advanced graphene batteries can be damaged by poor charging habits.

Battery Swelling

Graphene batteries improve heat control and stability but still share fundamental safety and performance hazards. The swelling occurs from:

• Overheating

• Overcharging

• Deep discharge

• Using incompatible chargers

• Physical damage

• Internal cell aging

• Exposure to high-temperature

If the battery is swollen, please get it inspected immediately at a REVOO after-sales service center.

Excessive Charging Concerns

Overcharging can still reduce battery lifespan; a faulty BMS or wrong charger may cause overheating, even with graphene’s improved heat control.

Heat During Charging

Graphene improves cooling but charging in extreme heat still causes temperature stress and performance loss.

Fast Charging Stress

Frequent fast charging generates extra heat and internal stress that gradually impacts overall longevity even in graphene-enhanced batteries.

Voltage Instability

Unstable or poor power supply reduces charging efficiency and may damage battery or charger protection circuits.

Deep Discharge Before Charging

Letting the battery drop below 20% causes stress and reduces its power time.

Improper Storage Charging

Capacity loss happens when batteries are stored fully charged or fully drained, while long-lasting health is preserved by keeping them at around a 50% charge.

Damaged Charging Port or Cables

When ports are damaged or cables are dusty, charging becomes slower and less stable. Regular care keeps your power supply smooth and safe.

Partial Charging Problem

Draining the battery to 0% regularly can stop it from reaching full capacity. This indicates damage and needs professional checking.

5-Battery Maintenance Methods

In addition to proper charging methods, good battery maintenance can significantly prolong the battery’s life. Here are some practical battery maintenance tips;

Maintain Charge During Storage

For long storage, maintain the battery at around 50–70%. After every month, add some charge if needed.

Check the charging level

Check the charge every month, recharge if necessary. Storing the battery at a low charge level can degrade its capacity

You should check your e-bike battery's charge every month and recharge it to about 50-60% if the level has fallen below 30%. Charging 50-60% is ideal for storage because a fully discharged battery can be permanently damaged while a fully charged one can lose capacity over time.

Stay in the Battery “Green Zone”

Keep the charge between 20% and 80%: This "Green Zone" minimizes stress on the battery cells. Avoid letting the battery drain completely (below 20%) or stay at a 100% charge for prolonged periods.

Avoid Deep Discharge

Deep discharging (completely draining the battery) can cause significant damage.

• Avoid waiting until the battery is completely dead before recharging.

• Recharge when the battery is low and when its capacity drops to around 20-30%.

Proper Battery Storage

Store the battery in a dry, cool place, away from direct sunlight and high temperatures. High temperatures and humidity can accelerate battery aging and reduce its performance.

Regularly Inspect the Battery

Regularly check the battery's appearance and connectors to ensure there are no visible damages or corrosion. If you notice any issues, contact a professional for repair or replacement.

Turn Off the Battery Breaker During Long Gaps

Turn off the battery breaker (air switch) when not in use for a long time

Charge Smart, Ride Safe

The battery is the key component of every electric bike; smart charging practices plus simple maintenance habits can significantly boost its lifespan. Check the battery condition, use the right charger and create a safe charging environment before charging. During charging, follow the proper steps and avoid overcharging or high-temperature charging. Regular battery maintenance and quick inspections help keep your e-bike running at its best. By using this easy guide, you can keep your electric bike a reliable companion for daily commutes and fun weekend adventures.
