Fr 5,500.00

Description

  • Module name: 4 string lithium battery protection board
  • Modular nature: polymer lithium battery protection board
  • Overcharge detection voltage: 4.25±0.025V
  • Overcharge release voltage: 4.15±0.05V
  • Over discharge detection voltage: 2.50±0.08V
  • Over discharge termination voltage: 3 ± 0.1V
  • Over current: 20-30A
  • Working current 15A (natural cooling: 10A, plus heat sink 15A, maximum instantaneous current 30A)
  • Termination condition: release the protection condition, then automatically resume without activation (optional charger activation)
  • Main functions: overcharge protection function, over discharge protection, short circuit protection, over current protection.
  • Working temperature: -40~+ 85 degrees (high temperature environment, please strengthen the radiation)
  • Connection: welding output
  • Module size: 50mm * 22mm * 4mm

Application:

The protection board can be used as a four-component polymer lithium battery pack with a nominal voltage of 14.4V, 14.8V, 16.8V, and a four-string 18650 lithium battery for overcharge and overdischarge, short circuit protection. There is no high instantaneous current to activate the function in the power supply application, and erroneous trigger protection is avoided in the inverter application, so it is more convenient to use.
