Quick breakdown into key components
The background electronics are a clever blend of three requisite circuits, that is to say, a lithium-ion battery charger circuitry, a battery protection circuitry, and a dc-dc boost converter circuitry. Refer to the annotated image provided below (and the table next to it) to get a deep insight on the underlying electronics.
| COMPONENT | DESCRIPTION |
| U9 = DW01V | 1S Li-Ion battery protection chip |
| F1 = 8205A | Dual N-Channel MOSFET |
| U2 = TC4056A | 1S Li-Ion battery charger chip |
| U7 = FP6298 | 4.5A current mode dc-dc boost converter chip |
| U4,U5,U6 = 662K (XC6206xxxx) | Positive voltage regulator chip (3.3V) |
| L1 = Green LED | Battery CHGD indicator |
| L2 = Red LED | Battery CHRG indicator |
| S1,S2,S4 = Schottky Diodes | S1 = SS14 & S2,S4 = SS24 |
In the 18650 Battery Development Board , the dc- dc boost converter chip is used to deliver 5VDC (actually 4.99V) through the USB ‘A’ socket and 5V male-header points, generated from the available 3.7V-4.2VDC Li-Ion battery output. The second channel output, marked as 3V but 3.3V on the dot, is supplied by the parallel combination of three positive voltage regulator chips. The 3.3VDC supply is derived from the 3.7V-4.2VDC Li-Ion battery output (not from the 5VDC output).
Package include:
- 1 pcs 18650 Battery shield V3 (does not include 18650 battery)
- 1 pcs cable

18650 Battery Insulation Paper Pack 1S (Solid) 10PCS
Features
- Adhesive cardboard paper for the 18650 battery insulator.
- Better protection to avoid short circuits on batteries.Easy peel-and-stick application
- It is especially resistant to the corrosion of acid and alkali, tear resistance, and wear resistance. Tear strength, rupture work, and dynamic strength are very high
- Good insulation, flexibility, water resistance, wear resistance, oil resistance, aging resistance, and good gap material
- It has the functions of insulation, shielding, and anti-interference, providing high electrical insulation, mechanical strength, softness, and elasticity.
Function
Insulate cell terminals and Ni tape to avoid short circuits when welding.
How to use it?
- Take off each insulation paper from the base paper.
- Put and stick upper hollow adhesive insulation paper on the top of the battery positive.
- Put and stick lower solid adhesive insulation paper on the negative.
- Then, you can weld Ni tape or Ni-plated steel plate with positive, and negative to make a battery pack.
