It can not fit LTO battery. Note: the default protective case is a kit, not assembled, suitable for NCM Ternary polymer lithium battery Li-ion, lithium iron phosphate battery LiFePO4.
The quiescent current is about 12ma, and the battery capacity is recommended to be used between 30-300AH! With under-voltage sleep protection, only detecting the battery voltage of B1, the equalizer will automatically stop entering the sleep state when the B1 voltage is lower than 2.7v, and the standby power consumption is less than 01mA.


The power range described is applicable to the following products: vacuum cleaner, solar street light battery pack, monitoring standby power supply, 12V electronic products, massager battery pack, LED light backup power supply, etc.
This protection board can not be used for iron ion polymer battery, hand drill battery pack, 775 4A or above motor, electric fish battery pack, 2 pieces and 24V series, electric bicycle battery pack, 1W fisheye LED lamp. It is small in size and suitable for many applications requiring high integration and low cost.




Widely usesupport 12v/4s, 24v/8s, and 06-2a active balance current, 48v/16s, 100a-350a max current lifepo4 battery system, 72V/24S, will be the perfect choice for your DIY system.
