This is a rechargeable Lithium polymer battery with a built-in USB charging port. We will provide a USBC charging cable.
Compared with the original Lead-Acid Battery ,
you can understand that the original battery is 2V * 470mAh,
Our battery is 3.7V *500mAh, 3.7V is stepped down to 2V through the chip, so at least 750 mAh of capacity can be obtained
There may be some loss in actual use,
but the actual capacity of lithium batteries is much greater than that of Lead-Acid Batterys.
The characteristics of lithium batteries are stable voltage and will not suddenly shut down when the battery is low.
With charging indicator light
So lithium batteries are a better choice.
