Can you check the remaining power of a 48 volt 20 AH lithium battery on a battery car? I think you can check the remaining power of a lithium battery from the key switch of your battery car. The remaining battery capacity can be. displayed on the screen

How to measure the capacity of lithium battery? How to measure with a multimeter.

The power consumption of Tailing electric vehicles is visible on the battery power dashboard. There are also compasses, energy-saving lamps and electronic displays of battery power, all based on the information provided by the operating voltage of the lithium battery.

Compass battery charging method, when driving, the hand indicates that the green area is powered, the ** arrow indicates that the power is insufficient, and the red arrow indicatesthat there is no power and cannot be used. It is recommended to charge the battery when the ** arrow is in the middle. When the battery car is placed, the battery voltage heats up and the pointer points to the green area, indicating prohibition. So it depends on the driving position of both hands. The power saving light indicates that the total battery capacity is ten. It is best to charge when the battery capacity reaches 3-4 batteries while driving. Because the working voltage of the battery will be preheated when the battery car is placed. It is prohibited to look at the indicator light, so it is prohibited to look at the indicator light while driving. Energy consumption should be used as a standard.

A multimeter cannot measure battery capacity. Battery capacity refers to the quaTotal amount of electricity released once the battery is fully charged and discharged until it stops discharging. In other words, capacity Q = product of current I and discharge time t. There are special instruments for measuring other battery parameters, such as battery testers.

A multimeter is a magnetoelectric instrument with a rectifier that can measure various electrical parameters such as alternating and direct current, voltage and resistance. For each electrical quantity, there are generally several ranges.

Also known as a multimeter or simply multimeter. The multimeter is composed of a magnetoelectric ammeter (meter head), a measuring circuit and a selector. By changing the selection switch, various electrical parameters can be measured easily.

Remarkson the use of multimeters

1. Before using the multimeter, you must first perform "mechanical zero adjustment", that is, when no electricity is measured, the multimeter pointer must point to the voltage zero position or zero current.

2. When using the multimeter, do not touch the metal part of the test lead with your hands. This can guarantee measurement accuracy on the one hand and personal safety on the other hand.

3. When you measure a certain amount of electricity, you cannot change speed during measurement, especially when measuring high voltage or large current, you need to pay more attention. Otherwise, the multimeter will be damaged. If you need to change gears, you must first disconnect the test leads and then measure after changing gears.

4. When using the multimeter, it should be placed horizontally to avoidErrors. At the same time, care should also be taken to avoid the influence of external magnetic fields on the multimeter.

5. After using the multimeter, you need to convertThe switch is set to the maximum AC voltage range. If it is not used for a long time, the battery inside the multimeter should also be removed to prevent it from corroding other components of the multimeter.
