Brief Introduction (I)Product model: HW-293Charging Voltage: DC 16.8-17.8VContinuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)Continuous charging current: maximum 20AProduct size: 45*60*4mmApplicable selection: suitable for lithium batteries with nominal voltage of 3.7V and charge of 4.2V(Including 18650, 26650, polymer lithium batteries) with electric drill below 170W
Power supply: 2.1 interface DC 8~25V power supplyChannel: 2*50w dual channel (stereo)Audio source input: Bluetooth connection stereo input, using CSR8633 Bluetooth chip, Bluetooth V4.0Output impedance: 8 ohms (can drive 4, 6, 8, 16 ohm impedance speakers)Output power: adding the front-end NE5532 output power is sufficientDIP switch: It is more convenient to directly adjust the gain of the power amplifier of the subsequent stage, and it is better to push the loudspeaker with larger damping

Product model: HW-147Charging Voltage: DC 16.8-17.8VContinuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)Continuous charging current: maximum 20AProduct size: 45*60*4mmApplicable selection: suitable for lithium batteries with nominal voltage of 3.7V and charge of 4.2V(Including 18650, 26650, polymer lithium batteries) with electric drill below 170W
Product model: HW-149Charging Voltage: DC 16.8-17.8VContinuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)Continuous charging current: maximum 20AProduct size: 45*60*4mmApplicable selection: suitable for lithium batteries with nominal voltage of 3.7V and charge of 4.2V(Including 18650, 26650, polymer lithium batteries) with electric drill below 170W
Product name: Bluetooth audio power amplifier moduleProduct model: HW-406Working voltage: DC3.7~5VOutput power: 5W*2Output load: 4Ω5W speaker
Product model: HW-428Charging Voltage: DC 16.8-17.8VContinuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)Continuous charging current: maximum 20AProduct size: 45*60*4mmApplicable selection: suitable for lithium batteries with nominal voltage of 3.7V and charge of 4.2V(Including 18650, 26650, polymer lithium batteries) with electric drill below 170W
Product name: 5A DC step-down CNC moduleInput voltage: DC 6.5-36V (the input voltage is lower than 6.5V, the current accuracy is not accurate, and the LCD display is abnormal when it is lower than 5.5V)Output voltage: DC 1.2-32VConversion efficiency: about 94%Working current: about 30mA
Product model: HW-356Charging Voltage: DC 16.8-17.8VContinuous discharge current: maximum 40A (if heat dissipation environment is not good, please reduce the use of load current)Continuous charging current: maximum 20AProduct size: 45*60*4mmApplicable selection: suitable for lithium batteries with nominal voltage of 3.7V and charge of 4.2V(Including 18650, 26650, polymer lithium batteries) with electric drill below 170W
