1. Can support charging and activation testing of 10 batteries of the same model (or a mixture of different models) at the same time 2. This fixture has a total of 10 charging activation test units, and the current limit of each unit circuit is 2A (designed based on the current limiting characteristics of the current battery protection version, the battery protection version automatically protect the charging current exceeding 2A). 3. Each set of charging units is equipped with for a series battery interface holder 4. When the main power supply is not connected, connect the battery to any unit circuit. The digital meter display the current voltage of the battery (it display normally if it exceeds 3.3V, and it not display if it is below 3V). 5. When the power supply is turned on, the battery on any unit circuit is short-circuited, which not affect the battery on other units to continue charging or other tests. It has large current overvoltage active protection function, and the unit design has a current limit of 2A. Located in front of the battery charging interface. It has a self-recovery function after large current protection, and the cooling recovery time is about one minute. The batteries in each charging unit not recharge with batteries in other charging units. The main power supply adopts a U-shaped loop design with balanced current distribution. When N batteries with the same power are at the same time, charging take a long time.
