SODIAL 4 string 14.8V lithium battery protection board 16.8V overcharge short circuit over discharge protection board 20A current limit protection
In the use of the battery will heat is the battery does not apply, this situation must not be long-term use, the battery will soon be damaged.
Note 1: strictly according to map wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not deliberately short circuit!
Note 2: after the need to charge the first line, will have output.
Note 3: 4 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please single DU full of batteries and then used in series. The The Discharge test, the voltage drop is fast that group of batteries is poor battery.
