বিবরণ
- Product Introduction
- The module is applicable to two or three channeled 3.7V lithium batteries. By short circuit setting, the default is two strings. When two strings are used, the module can use its own battery equalization function, which is very practical. The type-c port and welding wire can be used for input. When the type-c port is connected to the fast charging power supply, the charging voltage is automatically adjusted to improve efficiency. If the input voltage is less than the battery voltage when the welding wire is input, the module can only work in the boost state.
- Product Parameters
- Support QC fast charge
- 15W synchronous switching boost charging
- Boost charging efficiency 94%
- Can be set to charge 2 or 3 strings of lithium batteries
- 2 strings with balanced charging
- Adjustable charging current
- Input over-voltage and under-voltage protection
- Adjustable charging timeout protection
- Output over-current, over-voltage, short circuit protection
- Note: Normal use does not require too many setting modules, just choose 2 strings or 3 strings of charging as needed.
- Input: optional type-c port or wire bonding input, type-c access to QC fast charge can automatically adjust the charging voltage, improve charging efficiency, if the wire input, the input power supply should be less than the battery voltage (battery series connection * battery voltage).
- Output: support 2 strings and 3 strings, the battery needs to add a protective board, default 2 strings, when changing 3 strings, you need to shorten the short contact, and then remove the resistance next to it. When 2 strings can use the equalization function, the two strings of batteries are connected to the BM pin in the middle (this equalization speed is limited, and the two strings of batteries should try to ensure that the parameters are consistent when using).
- Current setting: The green arrow in the figure above refers to the default current of the two parallel current settings is 100K (0.9A) and 180K (0.5A). Resistors can be removed or replaced according to your needs. The calculation formula is current=90000/resistance.
- Battery charging up to the voltage setting, the default single string is 4.2V, the general battery is also this value, no need to change. If you need to change, you can set the board VSET resistor against the RVSET setup table.
- Charging timeout time setting, default no timeout time, set the ROT resistance value to set. 68K-4 hours, 120K-12 hours. no stick-24 hours.
- NTC access: normal personal use, if necessary, the NTC resistance value to 82K, NTC solder joints and GND next to the 100K thermistor (B=410).
- LED indicator: normal red light is on, the charging process blue light is on, the blue light is off after charging full, and the blue light flashes after detecting abnormalities.
