Features :
1- Built in with BMS :
a- Programble thresholds and monitor each cells' voltage, cells' group
temperature, and current.
b- Programable cell balance during charging and/or after charging.
c- Normal "open" relay switch out put for charge and discharge protection:
* Charging protection: swtich turn to "close" when cells' over voltage, over temperature,
over current not within preset thresholds.
* Dischargisng protection : switch turn to "close", when cells' under voltage, over
temperature, over current not within preset thresholds
Charging protection relay out put switch should connect to charger's trip circuit, and
discharging protection relay out put switch should connected to controller's trip circuit
to stop charing and discharging as required above.
Switch rating : 60V200mA
1- Computer diagionse : to read cells voltage, protective status, set parameter, and
calibration voltage and current group by group.
3- 2000+ 80%DOD of discharge cycle life .
5- Rugged construction (plastic case + cell mounting frame) battery pack housing.
6- USB socket on case

| Relative info: |
 |
- This LCD may show the voltage of each cell
- This LCD may show the fuel gauge of battery pack
- You may set parameter or calibration with USB port.
|
| |
|
 |
- Equilibria model features:
- May transfer energy from rich energy cell to lower energy cell directly
- No influence for other cells and components
- Other components won't influence this model
|
| |
|
| Due to the high quality and high efficiency equlibira device, this system also may work on HEV/EV , any kind of portable power and relative equipment. |
