Is it better to use dual lithium batteries or large capacity lithium batteries?

Dual lithium batteries and large capacity lithium batteries each have their own advantages, and which one you choose depends on your needs.

1. Double lithium battery: Double lithium battery refers to two small capacity lithium batteries that can be replaced alternately, which can improve battery utilization. Due to the small capacity of small capacity lithium batteries and the fact that lithium batteries cannot be over-discharged, the voltage should be left protected by the protection board, so a suitable new lithium battery should be selected for replacement.

2. Large-capacity lithium battery: The large-capacity lithium battery has a large capacity and releases a lot of energy before reaching the protection voltage, which can meet the needs of most people.

In summary, if you must use iter for a long time, it is recommended to choose a large capacity lithium battery.

The choice of lithium battery mainly depends on the voltage and capacity of the battery

Battery: the voltage should be the same as the motor voltage, or . higher than the motor voltage A little higher.

Battery capacity is measured in AH. At the same voltage, a higher capacity battery is larger. For example, if the motor working current is 10A and the voltage is 12V, then 10A*12V = 120W. If you use a 12V/10Ah battery, the motor can run for 1 hour.

The rated operating current of the 120W 12V DC motor is approximately 10A. The battery can store 40Wh of energy when working at the maximum power of 120W for 20 minutes. The required battery capacity is approximately 12V 4Ah. and lithium battery is a power battery.

The recommended combination is a lithium-polymer manganese battery with a single-cell capacity of 4-5 Ah, three in series, an operating voltage of 3*3.7 V = 11.1 V and a weight of battery of approximately 100 -200g. When lithium batteries are used in series, a protection board is required. ?
