12S-16S 13S 14S 15S 5A Capacitor Active Equalizer Balancer LFP Lifepo4 Lithium Lipo/Titanate LTO Battery Energy Transfer Active Equalization Module Faster Whole Group Balance

  • 【USE Tips】: The voltage gap of each battery must be within 0.5V. When the battery voltage difference does not reach more than 0.1V, the light on the balance board is triggered by mistake. The light actually has no balance current when it lights up, and it will automatically go out after a period of time. So We suggest re-plugging the cable to solve the problem.【Note that】It takes time to equalize the voltage, hot is normal and it does not take effect immediately after plugging it in..
  • Working Voltage: 1.8V-4.5V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4),lithium titanate battery (LTO). 【Tips】When buyers have problems, please be sure to take the initiative to contact us, and trust us have the ability to solve your problems, rather than a direct refund returns. This can prevent many products from being discarded and wasted..
  • Working Principle: Flying capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB. Balance current 0-5.5A, the more balanced the battery c....

  • Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid. When using for the first time, please charge and activate the protection board first.
  • 1100mah: The recommended charging current is 0.2A, the maximum is not more than 1A The discharge current is recommended 0.55A, and the maximum is not more than 3A.
  • Over-discharge protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect..
  • Overcharge protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged. form an overshoot protection..
  • Short circuit protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous ....
