Electric Board 3S Li-ion Lithium Battery 18650 Charger Battery Batteries Protection Board 10.8V 11.1V 12V 12.6V Electric

3 series 18650 12 V to 12.6 V lithium battery 10.8 V to 10.8 V protection board (can be used for more than three series, and maximum support and 20) Descriptions: 3 series (for three 18650 batteries or polymer lithium battery series combination) The rated voltage of 10.8 V (polymer battery) 18650 or 11.1 V (nominal voltage of 3.7 V lithium battery) 12.6 V voltage after a full battery (lithium) 20 a discharge (refers to the maximum discharge current limit) The attribute of the lithium battery protection board: Models: HX - 3 s - D021 charging voltage range: 4.25 + / - 0.05 v to 4.35 v Size: 51 * 23 * 4.0 mm discharge voltage range: 2.3 + / - 0.05 v to 3.0 v Maximum working current: 10 a working temperature: - 40 - + 50 ° Maximum instantaneous current: 15-20 a storage conditions: - 40 - + 80 ° Static electricity: less than 50 ua useful life: more than 30000 hours Resistance: less than 150 m short circuit protection, can protect, delay the recovery. The protection plate size and device description; The protection plate size of 51*23*4 mm;Components for seiko S-8254AA protection chip and authentic AOS IC:D403 * 4PCS; Notes: more than 3 a current discharge products, battery discharge rate is more than 3 c. Ratio calculation formula: 1 c rate of the battery, 2000 capacity is equal to 2 ah * 1 = 2 a maximum working current. 3 c ratio battery, 2000 capacity is equal to 2 ah * 3 = 6 a maximum working current. In use battery heats is ratio is not applicable, this situation must not be used for a long time, the battery will soon be damaged.
