Lithium battery protective board tester
This is a one/four series lithium battery protection board tester with high automation, friendly Chinese interface, fast test speed and high test accuracy. It has 11 performances such as over-charge, over-charge recovery, over-discharge, over-current recovery, internal resistance, self-consumption, short circuit protection, over-charge protection time, over-current protection time and over-discharge protection time.

One.Selection of test options:
Consumption Current, Internal Resistance, Overcharge Voltage, Overcharge Recovery Voltage, Overdischarge Voltage, Overdischarge Recovery Voltage, Overdischarge Current
Fast test (self-consumption parameter, internal resistance parameter, charge protection, charge recovery voltage, discharge protection, release voltage, over-current protection, short circuit protection, delay value)
Accurate testing (overcharge starting point, overdischarge starting point, overcharge restoring starting point, overdischarge restoring starting point, overflow starting point)
Two. Accurate testing
The test is accurate test , also known as slow test, which can test the parameters of the protective plate in detail.At the same time, the test data are sent to the computer together. First, when entering the exact test, it will enter the exact test interface.The interface first sets the starting point of overcharge voltage, overcharge recovery voltage, overdischarge voltage, overdischarge recovery voltage and overdischarge current.
