Parameters

Technical indicators

Indicator content
Product model DS0877/DS0877C
Applicable string number 8S
Applicable battery type NCM/LFP/LTO
Operating voltage range NCM/LFP: 2.7-4.2V  LTO:1.8V-2.7V
Balance voltage accuracy 5mV (typical)
Balance mode Active balance in which the entire battery group participates in energy conversion at the same time.
Balance current When the voltage difference is about 1V, the maximum balance current is 5A, and the balance current decreases as the voltage difference decreases. The minimum balance start voltage difference of the instrument is 0.01V
Undervoltage protection sleep voltage NCM/LFP: 2.7V  LTO:1.8V
Static working current 20mA
Working environment temperature -10℃-60℃
External power No external power supply is required, and the whole battery group is balanced by relying on the internal energy transfer of the battery.
Single string voltage range 1.0V-4.5V
Measurement accuracy 0.5% / ±5mV

 

Working voltage: 2.7V-4.5V.

Suitable for ternary lithium, lithium iron phosphate, lithium titanate.

Working principle, the capacitor fit transfers the charge mover. Connected the balancer to the battery, and the balancing will started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.

Max Balancing current 5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv.

With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA.
