Safety Every lithium ion battery pack should have (must have?) a safety board which monitors the charge and discharge of the pack, and prevents dangerous things from happening. The specifications of these safety boards are dictated by the cell manufacture, and may include the following: 1ï¼?Reverse polarity protection 2ï¼?Charge temperature--must not be charged when temperature is lower than 0° C or above 45° C. 3ï¼?Charge current must not be too high, typically below 0.7 C. 4ï¼?Discharge current protection to prevent damage due to short circuits. 5ï¼?Charge voltage--a permanent fuse opens if too much voltage is applied to the battery terminals 6ï¼?Overcharge protection--stops charge when voltage per cell rises above 4.30 volts. 7ï¼?Overdischarge protection--stops discharge when battery voltage falls below 2.3 volts per cell (varies with manufacturer). 8ï¼?A fuse opens if the battery is ever exposed to temperatures above 100° C.
