BMS 4S Balanced Charger for 4 x 3.7V Lithium batteries with protection
BMS4S
4S Balanced BMS (Battery Management System) for use with 4 x 3.7v Lithium batteries
This BMS is designed to charge and manage the use of 4 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 batteries from both over voltage and under voltage. It also features over current and short circuit protection.
This BMS will balance charge 4 lithium batteries like 18650 or 26650 or can charge multiple sets of 4 in paralel for higher capacity/current uses. It will also balance charge 4S LiPo (Lithium Polymer) battery packs.
Voltage in : 16.8V - 18.1VDC
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 45mm

Boost Converter DC-DC Step Up 4A Voltage Regulator
BCU4
4A DC-DC Boost Step Up Voltage Regulator
This voltage regulator uses the XL6009 (sucsesor to the LM2577) to make a very efficient DC-DC converter. It can take a 5V to 32V DC input and it will output between 5V and 35V DC at up to 4A. The voltage is set with the small built-in potentiometer. Surprisingly low noise despite being a boost converter.
Voltage in : 5V - 32VDC
Voltage out : 5V- 35VDC
Maximum Output Current : 4A
Dimensions : 43mm x 21mm x 15mm |

Boost Converter DC-DC Step Up 10A Voltage regulator
BCU10A
10A DC-DC Step Up Voltage Regulator (Boost Converter)
This step up voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take from 10V to 32VDC in and step it up to a higher voltage from 12V to 35VDC at up to 10A (output). The voltage is set with the small multi turn potentiometer.
note: If using this converter at its limits, you will need to fan cool the converter.
Voltage in : 10V - 32VDC
Voltage out : 12V- 35VDC
Maximum Output Current : 10A
Dimensions : 65mm x 35mm

Boost Converter DC-DC Step Up 2A Voltage regulator With USB
BCU2AU
2A DC-DC Step Up Voltage Regulator With USB (Boost Converter)
This tiny step-up voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take 2V to 24VDC in (or 5VDC via USB) and step it up to a higher voltage, up to a maximum of 28V at up to 2A (output). The voltage is set with the small multi-turn potentiometer.
Voltage in : 2V - 24VDC
Voltage out : 2.5V- 28VDC
Maximum Output Current : 2A
Dimensions : 36mm x 17mm
