Deskripsi
3 strings of 11.1V high current 100A, 3.7V ternary lithium battery protection board with balanced charging.
The properties of the lithium battery protection board:
Model: HX-3S-F100A Overcharge voltage range: 4.28v±0.05v
Size: 70*60*8.5mm Over-discharge voltage range: 2.5±0.05v
Upper limit working current: 100A (pay attention to heat dissipation) Working temperature: -40—+50℃
Upper limit instantaneous current: 100-120A Storage conditions: -40– +80℃
Quiescent current: less than 30uA Effective life: more than 30000 hours
Internal resistance: less than 300mΩ Short circuit protection: can be protected, delayed self-recovery.
Balance current: 65mA
Charging voltage: 12.6V-13V Charging current upper limit: 10A
Note on point T: Adding a normally closed temperature sensor switch can expand the temperature protection effect, and the 0R resistor next to the solder joint should be removed.
Note: For products with a current above 3A, the battery discharge rate should be above 3C.
Rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
In use, the battery will heat up, that is, the battery rate is not applicable. In this case, it cannot be used for a long time, and the battery will be damaged quickly.
Note 1: Strictly connect 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), C- charge negative, C+ charge positive, P- output negative P+ output positive, do not Intentional short circuit!
Note 2: After the cable is connected, it needs to be charged before there is output.
Note 3: When 3 groups of batteries are connected in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please fully charge each group of batteries and use them in series. During the discharge test, the group of batteries with a rapid voltage drop is the poor battery.
A note: Do not mix good batteries with bad batteries!
