Technical parameters
Operating voltage 1.8V-4.5V, suitable for li-ion, LiFePo4, lithium
titanate.
Working principle: the balanced work will be started when the
balanced board is connected to the battery. The original ultra-low
internal resistance MOS and 2OZ copper thick PCB are adopted, And
the balanced current is 0-5.5a, the more balanced battery, the
smaller balanced current.
The static current is around 12 mA. It is recommended that the
battery capacity should be in the range of 60-300AH!
With undervoltage dormancy protection, if the voltage is less than
1.8V, it will automatically stop into the dormancy state, standby
power consumption is less than 0.1 mA.
Li-ion/Lifepo4 /Lipo version
Balance start voltage: 3.0V-4.2V
Balance termination voltage: 2.9V (into undervoltage sleep state)
Maximum Balance current: The whole group error is 0.1V1A; 0.5V3.5A;
1.0V5.5A (18awg 30CM cable test)
3S quiescent current Full state: (4.2v*3cell) 12.6V 12mA
4S quiescent current Full state: (4.2v*4cell) 16.5V 15mA
7S quiescent current Full power state: (4.2v*7cell) 29.4V 15mA
8S quiescent current Full power state: (4.2v*7cell) 33.6V 14mA
Whether external power supply is required: no external power supply
is required, and the internal energy transfer of the battery is
used to transfer and the entire set batteries pack in balance .
Working environment temperature: 0-60 degrees
LTO version
Balance start voltage: 2.0V-2.8V
Balance termination voltage: 1.9V (into undervoltage sleep state)
Maximum Balance current: The whole group error is 0.1V1A; 0.5V3.5A;
1.0V5.5A (18awg 30CM cable test)
5S LTO quiescent current Full state: 2.8v*5cell) 14V 12mA
6S LTO quiescent current Full state: 2.8v*6cell) 16.8V 15mA
Whether external power supply is required: no external power supply
is required, and the internal energy transfer of the battery is
used to transfer and the entire set batteries pack in balance .
Working environment temperature: 0-60 degrees
It's for LFP,LTO,NMC batteries.
