Main features: high precision signal acquisition module，high precision SOC
estimation module, active energy transfer balance mode，the cell information
storage module, the cell protection module (overcharge protection, over
discharge protection, high and low temperature of cell protection), optional
LCD display module.
3 Package Information
The package is labeled with five descriptors
4 Features
4.1 Active balancing energy transfer type, high current is 1.5 A.
4.2 Optional battery balance modes: Automatic balance or Force balance.
4.3 Module reserved RS485 bus interface can be scaled to 32 cell, 48 cell and more
than thousands of cells.
4.4 Include a 4G SD card, can store 10 years for battery information.

Force Balance Mode
Balancing switch to position “I”. |
Balance when High - Low difference is
above 10mV. Stop balancing when the delta
is 10mV |
|
Automatic Balance Mode
(Default) switch position “0” |
(i) Balancing is always on: Monomer battery
differences over 60 mV starts automatic
balancing to 60mV.
(ii) Balance every 15 days, Balance when
High - Low difference over 60mV. Stop
balancing when the delta is 10mV or Day
