## How do you make a battery pack?

Divide by hours and you get amps, divide by amps and you get hours. For example a 5 amp hour **battery** is the same as a 5000 milliamp-hour **battery**. If you want to discharge in 10 hours, you can get a current of 5/10 = 0.5 amps. If you need 100 milliamps current, then you can run for 5000/100 = 50 hours.

## How many 18650 is 1kWh?

If you have, for example, 2Ah lithium ion **18650 battery** cell then each of those stores 7.4Wh (3.7V*2Ah=7.4Wh) of energy and you need 136 of them (1000/7.4 ~ 136) for a **1kWh battery**.

## How many 18650 do I need for 72V?

This **72V** lithium ion **battery** pack has a 20S10P configuration with 25Ah (amp-hours) capacity and 200A (amps) maximum continuous discharge rating (adjustable). This 200 x **18650 battery** pack uses a 20S10P Samsung 25R5 (INR18650-25R5) pack configuration.

## How do you calculate battery?

The key is to use the watts you know to **calculate** the amps at the **battery** voltage. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for 5 hours. Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours.

## How can I make my lithium-ion battery last longer?

**Boosting Battery Life**

- Use partial-discharge cycles.
- Avoid charging to 100% capacity.
- Select the correct charge termination method.
- Limit the
**battery**temperature. - Avoid high charge and discharge currents.
- Avoid very deep discharges (below 2 V or 2.5 V)
