1/5/10pcs 3S 12.6VDC Lithium Battery Protection Board Green For 12V Electric Drill Power Tool

Semi-finishedproduct : No High-concerned chemical : none Electronic : No DIY Supplies : Electrical Brand Name : Stlxy Origin : Mainland China

Suitable battery core: 3S three string 3.7V ternary lithium battery, maximum full charge voltage 12.6V ️ Strictly prohibited for use in 3.2V lithium iron phosphate batteries! PCB appearance: Green solder mask standard circuit board, compatible with mainstream domestic 12V charging drills and small electric tool battery compartment sizes on the market Circuit scheme: Multiple low internal resistance MOS transistors are connected in parallel to withstand the peak current of the motor starting moment, suitable for handheld electric tool loads Balanced configuration: Equipped with passive balancing resistors, the charging process balances the voltage of the three battery cells, suppresses the expansion of voltage difference, and extends the overall cycle life of the battery Complete set of comprehensive protection functions Overcharge protection: Single section 4.25V charging cut-off Overdischarge protection: Single section 2.5V cut-off output to avoid permanent damage caused by deep depletion of battery cells Overcurrent protection, load short-circuit self-locking protection, high temperature power-off protection Battery anti reverse protection, reducing the risk of board burning during spot welding assembly Applicable equipment: Domestic 12V lithium battery charging drill, electric screwdriver, small polishing machine, mini gardening electric tool Cell compatibility: compatible with 18650 power cells, supports assembly of multiple parallel battery packs, repair and refurbishment of old battery packs Charging matching: compatible with universal 3S 12.6V ternary lithium battery dedicated charger Designed for 3S ternary lithium battery, maximum full charge voltage at 12.6V. Green solder mask PCB with universal dimension matching most domestic 12V drill battery housings. Multiple parallel low internal resistance MOS tubes withstand instantaneous startup peak current of electric tools. Built-in passive balance circuit to equalize cell voltage difference and extend battery cycle life. Comprehensive multi-protection: over-charge, over-discharge, over-current, short-circuit and thermal auto cutoff protection. Reverse polarity protection improves stability during battery spot welding and assembly work. Ideal replacement board for 12V power drill, electric screwdriver and small handheld lithium power tools. Notice: Only fit ternary lithium cell,NOT compatible with lithium iron phosphate batteries. label:yes
