BMS 3S Balanced Charger for 3 x 3.7V Lithium batteries with protection

3S Balanced BMS (Battery Management System) for use with 3 x 3.7v Lithium batteries

This BMS is designed to charge and manage the use of 3 lithium batteries. It will manage the balanced charging when used with an apropriate constant current power supply for the batteries. It will also protect the battery from both over voltage and under voltage. It also features over current and short circuit protection.

This BMS will balance charge 3 lithium batteries like 18650 or 26650 or can charge multiple sets of 3 in paralel for higher capacity/current uses. It will also balance charge 3S LiPo (Lithium Polymer) battery packs.

A constant voltage/current power source is needed to properly use this BMS like the BCD5A or BCD9A

Voltage in : 12.6V - 13.6VDC

Over Voltage Protection : 4.2VDC per cell

Under Voltage Protection : 2.5VDC per cell

Maximum Charging Current : 20A

Maximum Discharging Current : 40A

Over Current Protection : 80A

Dimensions : 60mm x 41mm

Buck Converter DC-DC Step Down 5A Voltage regulator Constant Voltage Constant Current

5A DC-DC Step Down Voltage Regulator (Buck Converter) Constant Voltage, Constant Current

This step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take an input of 6V to 38V and lower it to between 1.2V and 36V at up to 5A (output). The voltage is set with one potentiometer and the constant current can be set with the other from 0.1A to 5A.

Voltage in : 6V - 38VDC

Voltage out : 1.2V- 36VDC

Constant Current Range : 100mA - 5A

Maximum Output Current : 5A

Dimensions : 52mm x 26mm
