Specification
Amperage : 8 milliamps
AudioDriverSize : 7.09 inches
AudioDriverType : dynamic_driver
AudioOutputMode : Stereo, Surround
Brand : Walfront
BulletPoint : Stereo Asymptotic Shelving Equalizer with M-S Processing 2-pole Highpass Lowpass Filters
BulletPoint1 : Stable Working: Nano amorphous isolated fully symmetrical transformer, ensuring minimum pressure difference. Ultra low internal MOS devices form an ultra low dynamic impedance inverter circuit, achieving high power balancing
BulletPoint2 : Auto Balancing: Intelligent MCU chip master management, which can achieve automatic and autonomous balancing work. Automatically detect the minimum voltage of the battery, stop working when the battery has low energy, and protecting the battery from power loss.
BulletPoint3 : High in Safety: Equipped with overcurrent resistors at each input end of the string, ensuring safety. Also equipped with automatic voltage detection and analysis function, it is convenient to understand the battery balance situation.
BulletPoint4 : Premium Design: Equipped with LED high definition digital display screen for clearer data observation. Design of inverter heat dissipation under extreme balance of high voltage difference.
BulletPoint5 : Good : Add a small short circuit breaker device for over temperature and over current , which can control the sudden abnormal excessive current, break the circuit at over temperature, and protecting the battery pack from normal and continuous balance.

How to Use:
A. Starting:
1. When the current drop through the board gets to 70mV or , the active equalizer automatically starts equalization. The actual current is related to the conduction internal of the MOS transistor on the board.
2. Human intervention initiates active equilibrium.
B. Balance Principle: High voltage energy is simultaneously transferred to low voltage parallel to achieve battery voltage balance.
