6S 22.2V 18650 Battery Protection Board PCB with Balanced Balance Function Charger Protect Module DIY BMS PCM PCB

Basic Parameters
  • Continuous discharge current: 8A
  • Instantaneous discharge current: 20A
  • Charging voltage: lithium battery charger 25.2V
  • Charging current: 25A max
  • Overcharge detection voltage: 4.28 ± 0.05V (single core)
  • Overcharge protection delay: 0.5S
  • Overcharge release voltage: 4.28±0.05V (single core)
  • Power balance detection voltage: 4.2 ± 0.05V
  • Power balance release voltage: 4.2 ± 0.05V
  • Battery equalization current: 45mA
  • Over-discharge detection voltage: 2.55±0.08V
  • Over-discharge detection delay: 0.1S
  • Over discharge release voltage: 2.9 ± 0.1V
  • Overcurrent detection voltage: 150mA
  • Overcurrent detection delay: 10mS
  • Overcurrent protection current: 75±5A
  • Overcurrent protection release condition: disconnect load
  • Short circuit protection condition: external load short circuit
  • Short circuit detection delay: 250uS
  • Short circuit protection release condition: disconnect load
  • Main circuit conduction internal resistance: =20MO
  • Working current: =30uA
  • Sleep current (current over discharge): =20uA
  • Temperature range: -20~+80 °C

  • In order to achieve a better balance of equalization, try to use a 25.6V switching source to charge (slow current below 30mA).
  • Because the equalization current of the equalization IC is about 45mA, and most of the lithium battery chargers on the market are 25.2V, the charging current detection will stop automatically when it is lower than 100mA.
  • Without the balance, no electricity is charged, causing the voltage of each battery to be unbalanced. Regarding the voltage drop between the battery voltage and the output voltage,
  • The working principle of this type of protection board is the protection of the negative pole. Some combination will have a voltage drop of 0.1-0.3V, and it will be normal to reduce the voltage drop voltage by charging and discharging several times.
  • The charger should try not to use the 25V power supply. The 6-string lithium battery is fully charged at 25.2V. The 25V power supply will not be fully charged, and the protection board will not be protected.
  • Long-term use has an impact on battery life.
