Shrink film for 2x18650 battery

Pre-cut insulating base for electrode, base without holes for 2x 18650 batteries. Self-adhesive pad isolates and protects battery contacts from short circuits. Stick to the battery after sealing it in a package.

NTC thermistor - with a negative temperature coefficient, i.e. an increase in temperature causes a decrease in resistance.   Thermistor NTC 50.0K 5% MF52A epoxy resin coating resistor features:

Size: 3mm
Rated resistance: R25 = 50.0k
B value 25/85 = 3950°K
Rated power: ‰¤ 50mW
Tolerance:± 5%
Operating temperature: from -40°C to +125°C  Tinned steel wire 25mm

Pre-cut insulating base for electrode, base with holes for 2x 18650 batteries. Self-adhesive pad isolates and protects battery contacts from short circuits. Stick to the battery after sealing it in a package. If the connecting tape becomes hot, insulation protects the battery against damage to the casing and against short circuits.

In the case of a battery pack, the BMS (Battery Management System) balancing protection circuit allows charging and discharging to be individually controlled. That is, the circuit controls that all cells are charged and discharged at approximately the same voltage. The current during charging should be limited, because the cell will "absorb" the current given to it, but a higher current than the one established by the manufacturer (generally a safe current is 1C ) can cause the cell to overheat and, in extreme cases, explode. The same relationship also applies to discharge.
