I. Product Overview:

DLS16E16B-01T35A is a lithium iron phosphate battery protection board designed and developed by Lithium Electronics Co., Ltd. It mainly applies 16 series battery packs and is applicable to lithium batteries with different chemical properties such as lithium ion, lithium polymer and lithium iron phosphate protection board. Overcharge protection, over discharge protection, over current protection, short circuit protection, temperature protection, charge balance management.

Two. Product Features:

◆ A-class protection IC IC Japan Seiko program.

With strong load capacity, continuous discharge current of 35A, the use of high voltage, low on-resistance of the power MOSFET, with a heat sink on the board, the cooling effect is good.

◆ A typical voltage detection over-charge protection, over-discharge protection. Hardware overcurrent.

◆ Short circuit protection, short circuit protection performance is stable and reliable, long time load short circuit will not affect the protection board and batteries.

◆ charge and discharge process corresponding temperature protection.

◆ temperature drift is extremely small, accuracy of 1% high power 2512 package detection resistance

◆ low power consumption, the current consumption is less than 30uA.

◆ PCBA board surface with high corrosion resistance, high water resistance, high impedance ESD three anti-paint coating

◆ Support more than 16 compound lithium battery direct series combination.

include matchable sampling cable connector:


When the protection board is connected to the battery, start with B· and then BI.B2 B3 ", and so on. Connect in order. When connecting head cables, please do not insear protection board into head cable to avoid damage, resulting in the protection board can not be used normally Therefore, after you have connected the head cables, then you can plug in the protection board
