Item weight:0.11 Kilograms Descriptions: This battery control module, features automatic charging, automatic power off, suitable for storage batteries and lithium batteries. Parameters is adjustable and can be saved in memory after power failure. Specification: Control Voltage: 10V-60V Control Current: 30A Control accuracy: 0.1V Voltage Deviation: 0.1V Application: storage batteries and lithium batteries Size: Approx. 9.5*6*3.3cm / 3.7*2.3*1.2inch Weight: 110g Product settings: For example: Take 12V battery for example. Press S1 key until the digital tube flash to set the over-voltage is 14.4V. Press S2 key until the digital tube flash to set the under-voltage is 10.5V. When the battery is below 10.5V, the load should be disconnected after 6 seconds delay. If the battery voltage is restored to more than 10.5V in 6 seconds, the load will continue to work and the delay will be operated not properly due to the fluctuation of the battery voltage when the large current load is started. When the load is disconnected, the module is connected to the charger, and the load stops charging when the load is up to 14.4V. Note: When the under-voltage value cannot be increased, adjust the over-voltage value first. Connect battery first for the module is powered by the battery Package Included: 1 x Battery Control Module [EFFICIENT BATTERY CONTROL] - This battery charging controller provides automatic charging and power-off functions, ensuring efficient use of batteries and lithium batteries.
