2pcs Li-ion Battery Voltage Step Up Boost Charge Management Circuit Board Module ++ Product Description ++ Its circuit structure is divided into three parts: a. Battery management is responsible by IC and a MOSFET, protect the battery against overcharging or over discharging; b. BOOST circuit is responsible for increasing the voltage; c. Simple current-limiting and unidirectional power device is to charge the battery. It has perfect protection functions, such as short-circuit protection. 3.7V-12V 300MA DC-DC Voltage Step Up Power Boost PCB Module with Charge Battery Management Module size: 22 x 17 x 6mm (single) Charging Input voltage: 5-6V Battery input voltage: 2.6-4.2V Output voltage: 12V 300MA (voltage output connector requires welding, for the specific location, please refer to in the picture in the user manual) Charging finish voltage: 4.2V Discharging finish voltage: 2.6V (suitable for common lithium battery, such as a common 18650 battery) Conversion efficiency: 90% @input 3.7V output 12v 200mA Standby current: 600uA @ input 3.7V Charging current (MAX): 400MA @ BAT = 2.8V It inputs charging voltage via a MICRO USB, compatible with most current mobile phone charger. You can adjust its output voltage, but you need to change the parameters of one or two resistors (which is 0.6 x 0.3 inch in package size). For the detailed methods, please refer to our user manual. If you load and charge at the same time, and need to work long hours, you need to reduce the current and consider the heat dissipation problem. The above parameters are only for pure resistive load, if the load is capacitive or inductive in nature, it may work abnormally. In the high frequency mode, the voltage may subject to some interference, not suitable for interference-sensitive devices. Please note that the meaning of the symbols on the PCB and connect them correctly, or it will damage the product.
