About ebike batteries. They’re most often measured by nominal voltage. Nominal voltage is just a fancy way of saying the average voltage. This is because each cell inside a battery can hold a specific range of volts. Most Lithium-Ion batteries (Li-Ion) will have 18650 cells inside. But BtrPower battery is soft polymer pack. it's more stable and safer than 18650 cells. Li-ion battery cells hold 4.2V when fully charged and 3.0V when discharged.48V batteries generally have 13 cell clusters. Most ebike motors will accept either 36 or 48 volts. These are the two most common nominal voltages. so take about...

Wiring a battery in series is a way to increase the voltage of a battery. For example if you connect two of 12V 10 Ah batteries in series you will create one battery that has 24V 10Ah. Since many electric motors in kayaks, bicycles, and scooters run on 24V this is a common way of wiring batteries. Wiring a battery in parallel is a way to increase the amp hours of a battery. For example if you connect two of 48V, 30 Ah batteries in parallel you will create one battery that has 48V 60Ah. How to connect     Wire...

Choosing a different type of battery is the biggest change you will find from one product to another. It is not just a simple question of choosing between a sealed lead-acid, nickel based battery or lithium battery, there are many variations of each type of battery and myriad results that each one has. Sealed lead-acid These batteries have been around for over 100 years, so the technology has been refined over time. On the plus side, they are the cheapest out there and can be easily recycled. This is great for people who are building their own bikes on a...

Charge according to standard time and procedure, even the first three times. When ebike display shows a low energy during riding, the lithium battery should be charged as soon as possible. Lithium battery don't require special methods to activate. it will naturally activate when running For the shipping safely, so the ebike battery has half of power at the factory, so you must fully charge the battery before using it. When you ride each time, don't drain the battery. If it runs out, it will greatly reduce the service life of the battery. Remember! ! Because the lithium battery has no memory effect, it...

How to choose Voltage ? It depends on the voltage of motor and controller. 36V motor and controller,choose 36v battery. 48V motor and controller,choose 48v battery. 60V motor and controller,choose 60v battery. 72V motor and controller,choose 72v battery. Note: Don't choose the wrong voltage,otherwise ,it will destroy your ebike How to choose Capacity ? The larger capacity,the longer battery life. "Battery life" means the time battery will continues to discharge before it must be recharged It also depends on the power of motor . The motor power is large,the corresponding current is large, choose a large capacity battery.Conversely,The motor power is small,the corresponding...
