Product Details
  • 13S Battery Equalizer--The equalizer has 13 serial ports, the working voltage is 2.0V‑4.5V, and is generally used for ternary iron lithium batteries
  • High Current--Inductive energy transfer equalization board with high current of 1.2A, significantly balances the battery voltage and improves the overall efficiency of the battery pack
  • Balance Principle--Balance starts when the voltage difference between adjacent batteries is more than 0.1V, and stops until the voltage difference is within 0.03V
  • High Equalization--Equalizer provides balance work, the battery pack voltage error will be pulled back to an ideal value, reducing battery maintenance costs
  • Low Internal Resistance--Built in improved ultra low internal MOS, the balance current is 0‑1.2A, and the battery voltage difference is smaller

  • Manufacturer: Walfront
  • Package Quantity: 1
  • Part Number: Walfront0qb9ho8an127589

Specification:
Item Type: Battery Active Equalizer
Material: PCB
Harness Specification: 22AWG
Technical Parameter:
Working Voltage: 2.0-4.5V, universal for ternary iron lithium battery, not suitable for LTO lithium titanate battery
Balance Current:
Adjacent voltage difference more than 0.1V, the current is about 0.5-0.7A
Adjacent voltage difference more than 0.2V, the maximum equilibrium current is 1.2A

Wiring Definition:
B-, the total negative pole of the battery pack (the negative pole of the first battery)
B1, the positive pole of the first battery
B2, the positive pole of the second battery
B3, the positive pole of the third battery
B4, the positive pole of the fourth battery
B5, the positive pole of fifth battery
B6, the positive pole of the sixth battery
B7, the positive pole of the seventh battery
B8, the positive pole of the eighth battery
B9, the positive pole of the ninth battery
B10, the positive pole of the tenth battery
B11, the positive pole of the eleventh battery
B12, the positive pole of the twelfth battery

Package List:
1 x Battery Active Equalizer
1 x Cable

Note:
1. Because of the working principle of adjacent equalization, it cannot be used as a maintenance tool.
2. It need to connect the battery and used together with lithium battery .
3. The pressure difference generated by charging and discharging the work of the equalizing plate to realize energy transfer and equalization.
