The dual lithium battery vehicle AD lights are good.
1. Strong durability: The LED light source used in dual lithium battery vehicle AD headlights has a long service life, strong resistance to earthquake and vibration, and can work stably for a long time on roads difficult. terms. It has relatively high reliability and durability.
2. Environmental protection and energy saving: The LED light source used in AD double lithium battery headlights does not contain harmful substances such as mercury, has no ultraviolet or infrared radiation, and is harmless to the environment and human health.
5V1A charges two lithium batteries connected in series. What is boost circuit?
1. You need to find two relatively thick wires that follow the rules and find the positive and negative polestifs of the two sets of 60v20a batteries.
2. Use two wires to connect the positive poles of the two sets of batteries to the positive pole and the negative pole to the negative pole.
3. Remove two positive and negative wires between the positive and negative poles of the two sets of batteries and connect them to the electrical appliances that need to be used. two batteries.
USB5V 7.4V boost charging requires MC4068 boost chip, 3.3uH inductor, SS32 Schottky diode, optional AO3402 or AO4410 MOS power tube, input capacitors and output are 22uF each, current limited resistance, red LED and green common cathode indicator F3. During the charging process, the charging light will be red and once fully charged, the green light will be on. The advantage of external MOS is that it can increase large current.
