Lithium Battery Charger Module J5019, 4.2V 1A, Circuit Board
$5
A circuit board to charge or discharge 3.7V Li-ion 18650 battery and/or Li-Po Lithium-Polymer battery, 1A max charge current & 4.2V charge voltage. Commonly labelled as a J5019 or TP4056 module. Brand-new, unused, sealed in an anti-static bag.
This circuit board is a very compact module which will charge most types of (3.7V) Lithium 18650 battery or single cell Li-Po batteries from either a 4V to 8V power supply input, or from a standard 5V USB-C plug/socket input.
A battery charge LED and standby LED are also included for visual indication.
Quick Spec:
Input Voltage (USB): 5V
or Input Voltage (IN): 4 to 8V DC
Battery Type: LiPo 3.7V or Li 18650
Charging voltage: 4.2V DC
Maximum Charging Current: 1000mA
Discharging current: Max. 2A
Dimensions: 33 x 24mm / 1.3" x 0.91"
Weight: 6g
The Vout Ports can output an adjustable voltage:
Output Voltage: 4.3 to 27V DC, user adjustable by pot (continuously adjustable)
Max Output Current: 1A (not protected against short-circuit).
The battery charger circuit incorporates the DW01A battery protection IC/chip, which protects the battery from over- and under-charging, reverse connection and short circuit.
This same circuit board has several funcionalities. As well as providing 4.2V for Lithium battery charging, it can also (and simultaneously, if desired) provide a user-adjustable 4-27V DC output on the Vout terminals, which is adjusted by trimming the on-board potentiometer. This module can be used to provide DC->DC Voltage Step Up Boost, giving for example 6V / 12V / 24V output as desired (continuously variable) from either the 3.7V Lithium battery or the 4-8V/USB input.
The following U-Tube video shows some of these uses: https://www.youtube.com/watch?v=rVLlKuDx0tM
It can be used (for example) to replace the conventional 9V battery in many multimeters with a USB-rechargeable 18650 Li battery.
A very useful circuit which helps save a lot of space and integration of multiple systems.
You will need some basic understanding of electronics and ability with soldering etc to use this module; it is not plug-and-play.
Also, since certain parameters are not protected against overload, I cannot offer any refunds.
Discount available if you buy 4 or more units.
Please leave a Gumtree Message to arrange a time to inspect or collect.
