4S 1.2A Li-ion Lifepo4 Battery Inductor Based Active Equalizer BMS

Description

4S 1.2A Li-ion Lifepo4 Battery Active Equalizer BMS.

4s Inductive

DESCRIPTION:

  • This is a 4S LiFePo4/lithium ion 1.2A equalizer used for 12V battery pack.
  • This device acts as a balancer/equalizer to balance the capacity of cells inside 12V battery pack.
  • This is not a Bluetooth balancer/equalizer.
  • This can be used in lithium batteries of any type including 18650/21700/32650/38120/66160 and any type of prismatic cells etc
  • This can be used in lithium battery applications including solar, RV, Electric bikes, Skate board, camping, Boat, Power tools, Lawn moving and household energy storage systems.
  • This can be used for 3S and 4S battery pack configurations.
  • This is manufactured by Heltec.

Inductive energy transfer equalization board, high current 1.2A energy transfer battery voltage balancer, significantly balance battery voltage, improves the overall efficiency of the battery pack!

Balance indication:

  1. When the equalization light is on, the equalization work is turned on.
  2. The equalization light goes out, the equalization circuit sleeps,
  3. The equalization light flashes, the string indication is lost, or the circuit is faulty.

There are two different types of Battery equalizers:

  • Passive Battery Equalizer or balancer(Passive balancers)
  • Active Battery Equalizer or balancer(Active balancers)
  • The active battery equalizer in this method the battery equalizer have inductor or capacitors to balance the batteries they will use  using their extra energy that stores in the battery with higher voltage to charging the other battery that has lower voltage so the active battery equalizer has higher efficiency than the passive type but it is expensive.
