There are many types of lithium batteries. The maximum discharge current of ordinary lithium batteries is 1C, the discharge current of high-rate lithium batteries is 4C, and the discharge current of electric batteries is 10~20C. C here refers to the battery capacity, which means that the maximum discharge current of an ordinary 1000 mAh lithium battery is 1000 mA. The maximum discharge and charge of the 1000 mAh battery can reach 10 ~ 20 A. For example, our mobile phones use ordinary lithium batteries, while some model aircraft, electric cars, electric drills, etc. use ordinary lithium batteries. use lithium batteries, also known as lithium iron batteries. The voltage of electric batteries is lower than that of ordinary lithium batteries.
For an engine like yours, it is preferable to use a power battery of the capacity that youou deem appropriate. The power supply battery current of 20 Ah/24 V is sufficient.
The maximum instantaneous discharge current depends on the internal resistance of the battery and the protection plate. The short circuit current of ordinary 1000 mAh lithium battery is also more than 10 A, but for battery safety reasons. , the protection plate is limited to about 3A. Generally, the internal resistance of power batteries is very low.
