This is the SUNKKO 4S 5A Active Balancer Equalizer Module. The designed SUNKKO battery active equalizer adopts the latest high-frequency transformer inversion and equipotential isolation coupling technology, connecting each battery series in a parallel way, realizing the energy transfer and distribution between batteries with different voltages.

4s 5A six types of equalizers meet your different battery balancing requirements. The superior components, well-designed circuit, and exquisite PCB craft bring you an efficient and reliable battery equalization experience.

Features & Specifications:

• Good quality product
• Easy to use
• Multiple Choices & Excellent Equalization Effect
• The newly designed SUNKKO battery equalizer adopts the latest transformer inversion active energy transfer technology to balance the voltage difference of large-capacity battery packs, recover battery capacity, refresh your battery pack, and extend the battery usage life.
• 5A super equalizing current realizes the ultra-fast energy transfer between each string battery. The equalized voltage difference can be reduced to 0.01-0.02V, bringing you an efficient and reliable battery equalization experience.
• Two equalization modes: 1h timing equalization mode and forced continuous equalization mode.
• The aluminum cooling fin dissipates the heat rapidly when the equalizer is working, the detected temperature of the full load device is 98.6 ℉.
• Suitable for 4 series ternary lithium battery and lithium iron phosphate battery.
• Equalization Way Parallel Energy Transfer
• Equalization Mode 1H Timing & Forced Continuous
• Equalizing Current is Adjustable within the range of 0 to 5A.
• Designed for use with 4S battery configurations.
• Utilizes a 3.81 wire connecting terminal, specifying the type of terminal used for wiring.
• Requires a minimum battery voltage of ≥3.2V for proper operation.
•  Automatically stops operation when the battery voltage drops to ≤2.7V/2.5V, ensuring protection against deep discharge.
•  Features an auto-start voltage gap of ≥70mv, indicating the voltage difference required to initiate an automatic restart.
• Requires a voltage gap of ≤20mv to trigger the auto-stop function, preventing further discharge.
