Yes, we have both diodes and fuse in our lisocl2 power-type battery packs, and fuses are connected with batteries in series and diodes in parallel. Please see the drawing below:

Lithium Sulfuryl chloride (Li-SOCl2) batteries, such as ER34615M and ER26500M batteries, are known as Primary batteries for their high energy density, long shelf life, and excellent low-temperature performance. However, if handled improperly, they may pose safety risks.

To ensure the safe use of Li-SOCl2 batteries, GMB usually adds additional protective circuits to the battery pack or module. This circuit can include fuses, overvoltage protection, under-voltage protection, overcurrent protection, and thermal protection.

Fuses are usually used in battery packs to prevent short circuits. A fuse is a safety device designed to disconnect a circuit when the current exceeds a certain level. In battery packs, fuses can be used to prevent battery damage and prevent safety hazards such as overheating and fire.

Thermal protection is another safety feature that can be integrated into the battery pack. Thermal protection can be achieved by using thermal fuses or PTC devices. A thermal fuse is a safety device designed to disconnect a circuit when the temperature exceeds a certain level. PTC devices are a type of thermal protection device that increases resistance with increasing temperature, thereby limiting the amount of current flowing through the circuit. Both devices can be used in battery packs to provide thermal protection.

It should be noted that not all Li-SOCl2 batteries or battery packs include fuses or thermal protection(NTC). It is always recommended to follow the GMB's guidelines for the use and handling of batteries or battery packs, including any recommended safety measures. It is also important to handle Sulfuryl chloride lithium batteries and battery packs carefully to prevent short circuits and other safety hazards.
