It contains an internal management circuit of rechargeable battery (including constant current charging circuit, the floating protection for battery, battery discharge control, 0 second battery automatic conversion circuit, etc.) it can be used in some uninterruptible power supply equipment which is particularly strict at the power.RemarkVarious dimensions and other output can be ordered according to your requirements.
