It delivers up to 8A continuous current with peak bursts of 10A, while providing essential protections against overcharge, over-discharge, short circuits, and overcurrent. Engineered for durability and precision, this module ensures stable battery operation across a wide temperature range, making it ideal for DIY battery pack builders and professionals seeking reliable power management. ## Description Feature: Model: HX-3S-03 For Lithium Battery Operating Voltage: 10.8V~12.6V Overcharge Voltage Range: 4.25-4.35v±0.05v Over-discharge Voltage Range: 2.3-3.0v±0.05v Upper Limit Working Current: 6-8A Working Temperature: -40---+50 °C Upper Limit Instantaneous Current: 9-10A Storage Conditions: -40-- +80 ° C Quiescent Current: less than 30uA Internal Resistance: less than 100mΩ Size: 30*30*2.8mm Protections: Short circuit protection, overcharge protection, over-discharge protection and over current protection. Short Circuit Protection: protection, delay self-recovery. Application: 10.8V(3.6V*3S) lithium battery & packs 11.1V(3.7V*3S) lithium battery & packs 12.6V(4.2V*3S) lithium battery & packs Note: Prismatic Lithium polymer battery (Li-Po) Could also work for 3S2P(6 cells), 3S3P(9 cells),3S4P(12 cells) etc. Review: Charge the bms and battery after hook up and the bms wakes up. - Everything works. Gotta hook up charger to p+ p- to wake up bms then the bms reads voltage at P- P+ Review: These were great. Don't foreget to wake them up after assembly with a charger or a 12 volt battery. - I built some battery packs out of old 1860 Lion cells I had laying around. One thing to be aware of is that once you put it together you must hook it up to a 12V charger or battery to wake up the BMS. I didn't know this at first and though they weren't working. The size and shape are perfect for making a battery pack inside a PVC pipe with caps. ## Features - 【Lithium Battery Operating Voltage】: 10.8V~12.6V - 【Multiple Protections】: Short circuit protection, overcharge protection, over-discharge protection and over current protection. - ★Compact size and lightweight, fine workmanship and durable, stable performance. - 【Applications】: for 10.8V(3.6V*3S) lithium battery & packs; 11.1V(3.7V*3S) lithium battery & packs; 12.6V(4.2V*3S) lithium battery & packs. - 【Note】: Please according to the diagram wiring to avoid possible damage to the chip. After connection, it need to charge activation first, then will have the output. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B5T1ZCTX | | Best Sellers Rank | #155,047 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #625 in Power Converters | | Customer Reviews | 4.5 4.5 out of 5 stars (10) | | Date First Available | July 5, 2022 | | Item Weight | 0.634 ounces | | Item model number | HX-3S-03 | | Manufacturer | Alinan | | Package Dimensions | 3.94 x 2.32 x 0.28 inches | ## Product Details - **Brand:** Alinan - **Color:** silver,red,green - **Input Voltage:** 3.7 Volts - **Item Weight:** 0.02 Kilograms - **Output Voltage:** 12 Volts ## Images ![Alinan 6pcs 3S 8A 12V 18650 Lithium Battery Protection Board 10.8V 11.1V 12.6V BMS PCM PCB Overcharge Over-Discharge Protection Module for 3 Li-ion Cell Pack - Image 1](https://m.media-amazon.com/images/I/81+L-l7HlfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Charge the bms and battery after hook up and the bms wakes up. *by J***H on September 6, 2024* Everything works.
