Holder for 18650 lithium battery
Holder for 18650 lithium battery

18650 battery holder allows easy use of lithium batteries in 18650 packaging. Otherwise, soldering these types of batteries is not recommended because the high temperature makes them lose their capacity. If you do not have a spot welding machine, we recommend that you get this kind of battery holder and you won’t have any problems with the loss of capacity, and it will allow you to use the batteries easily.

Power supply 5V 4A 20W
Power supply 5V 4A 20W

Small, industrial power supply in the metal housing allows the conversion of 230V AC to 5V DC voltage of maximum current 4A, power 20W.

Solar panel 1W 6V
Solar panel 1W 6V

A small solar panel that will keep your Internet of Things alive for a very long time, but also for many other projects. It has waterproof silicone to protect the panel from water and sunlight.

 

1S Li-Ion battery protection
1S Li-Ion battery protection

A battery protector is, simply put, a device that makes sure that something bad doesn’t happen to the battery. This small circuit board protects your lithium battery (of any capacity) from overcharge, overdischarge, overcurrent and short circuit. It has a JST connector for connecting the battery, and the battery can be directly soldered.

 

Protects from: undervoltage, overvoltage, overcurrent, short-circuit current

Protection IC: DW01

• Battery configuration: 1S1P (1-serial, 1-parallel)
• Battery type: Li-ion, Li-poly
• Dimensions: 22 x 22mm

Li-ion charger with protection
Li-ion charger with protection

Lithium batteries are charged differently than regular batteries and devices. You’ll need a li-ion charger like this one to charge them. Integrated with the CC/CV charging technology, it is the simplest way to charge a lithium-ion battery.

The board has a USB Type-C connector for power, a JST-type connector for batteries, the charging circuit, a protector, and two status LEDs. Comes with 7 pins that need to be soldered.

 

Product usage tips:

The red LED glowing means the battery is charging. The green LED glowing means it finished charging. Easy embedding into a project with the four mounting holes on the board.

 

Note: This charger has protection against short-circuit, too high, or too low voltage. It has no protection against reverse polarity.

Power supply 5V 2A 10W with USB output
Power supply 5V 2A 10W with USB output

A classic small power with an output of 5V / 2A which will ideally supply your project with an Arduino / Croduino. The output is standard female USB connector (type A). You can directly connect a cable from the PCB to the charger and use it as a constant power source, or it can be used for charging up a mobile phone/tablet. Or for a third purpose ..? In any case, it will be enough!
