Battery pack

(R-1047C_HS80G-L_Assembled_Accupack.pdf)
The battery pack contains 8 pcs of 1500 mAh rechargeable batteries. The pack is drained at the fourth cell. This output
supplies the date / time IC and the record storing RAM with power when the device is turned off.
We have built a thermistor into the battery pack as well, which checks battery pack heating during charging. As a final
check we have built in a thermal protection fuse that breaks at 72°C. Take note of this fuse when servicing the device,
as it may break with too much heat (for example when soldering). Instead of soldering we recommend cold extrusion
or soldering with continuous cooling.
