How Long to Charge a 48v Ebike Battery? Don’t Overcharge

The battery of an ebike supplies power to the motor and there are various types of ebike batteries available such as 36v, 48v, 52v, 60v, and 72 volts. The majority of electric bikes come with 48v batteries because of their excellent efficiency, superb power, longer range, and speed.

Charging an ebike battery with the right charger is very simple but most people don’t know how long to charge 48v ebike battery to maintain its performance for a long period of time.

Don’t worry! This article will help to understand the charging time of a 48v electric bike battery, factors affecting charging time, and important faqs related to your query.

How Long to Charge 48v Ebike Battery?

48V Ebike Battery Charging Time

You need a charger that is compatible with your 48v battery. When you have the right charger for your ebike battery, it may take somewhere around 4-6 hours to fully charge the 48v ebike battery from zero percent.

I mean your charger voltage must be equal to your battery’s voltage i.e., you need a 48v charger to charge 48v ebike battery. And the charger comes with different Amp ratings such as 2-Amp, 3-Amp, 4-Amp, and so on.

Avoid overcharging your ebike battery as it may get damaged internally which will reduce its lifespan. It is advised to charge your ebike battery to 80% only. However, If you are charging the 48v battery for the first time, 8 to 12 hours of charging time are recommended.

Honestly, I charge my 48v 10ah step-over ebike for 4 hours with a 3 amp charger. Also, I set up a reminder alarm so that I do not forget to disconnect the charger. As well as I have done a charging experiment with different types of chargers with 48v 10ah battery, here are the results:

48V 10Ah charging time according to the charger type

Most ebikes are equipped with a 48V 10Ah lithium battery i.e., 480Wh. This battery can easily manage up to a 500-watt ebike motor. You know, It’s very simple to calculate the charging time for an ebike battery, Here is the formula:

Ebike battery charging time = Battery's AH/Charger Amp
Charger Capacity (Power)Charging Time (Approx.)
2 Amp Charger5-6 hours
3 Amp Charger4-5 hours
4 Amp Charger3-4 hours
5 Amp Charger2-3 hours
6 Amp ChargerUpto 2 hours

As you can see the high amp chargers are taking less time and vice-versa. I would not recommend using high amp chargers to charge a 48v ebike battery. Use only those chargers that your brand recommends. Let’s see the charging time for 48v batteries with various AHs.

48v 20Ah charging time according to the charger type

48v 20ah ebike battery is a very powerful battery i.e., 960Wh. It takes more time to fully charged as compared to a 48v 10ah battery. As it is a powerful battery so it does not come with a 2-Amp charger. Therefore, we have tested this battery with 3-Amp to 6-Amp chargers.

Charger Capacity (Power)Charging Time (Approx.)
3 Amp Charger6-7 hours
4 Amp Charger5-6 hours
5 Amp Charger4-5 hours
6 Amp Charger3-4 hours

Also, charging time may vary because there are many factors that affect charging time. Let’s discuss them.

5 Factors Affecting Charging Time of Electric Bike Battery

  1. The battery charges faster with a higher amp charger than one with a lower amp. But high amp chargers may damage your battery therefore, I would recommend you use the charger that your manufacturer or ebike brand provided.
  2. The state of charge also affects the charging time, If your ebike battery is already low or zero percent, it will take a long duration as compared to charging a partially charged (40%) battery.
  3. Avoid charging your ebike battery when it has a high temperature because it will take a long time to charge as well as reduce the battery’s lifespan.
  4. Branded Lithium-ion batteries are charged quickly as compared to traditional batteries. So, always get a top-quality li-ion battery.
  5. Higher the capacity, the longer the duration to charge the ebike battery and vice-versa. For instance, A 36v ebike battery would take less time to charge as compared to a 48v battery with a 3 amp charger.

How Long Does a 48v Battery Last?

how long do e-bike batteries last on one charge

As you know that the 48v ebike battery is powerful and generally takes around 4-6 hours to fully charged with a 3-Amp charger. However, It’s also important to know how long does a 48V ebike battery last on one charge, and for what distance (48v ebike battery range).

Ebike battery’s range is dependent upon its Amp-hours (AH). Higher AH provides more range on an ebike and vice-versa. Also, there are other factors such as type of terrain, rider’s weight, weather conditions, and so on.

Let’s discuss in detail how long will a 48V battery last with various AHs.

How long will a 48V 10AH battery last?

48V 10Ah ebike battery is the basic model for an ebike battery which has electric power up to 480 WH (It can provide 480w electricity in an hour to an ebike motor). And this ebike battery can be paired with a 250w ebike motor, 350w ebike motor, and 500w ebike motor.

A 250w ebike consumes less power than the 350w and 500w ebike motors resulting in more range, hence a 48V 10Ah battery lasts for around 2 hours with a 250w ebike motor.

A 48V 10Ah electric bike battery would last for:

Ebike MotorEstimated Time
250-Watt2 hours
350-Watt1.5 hours
500-Watt1 hour
