It features a robust protection board with an auto recovery function, ensuring safety and longevity for your battery pack. With a peak current of 40A and precise voltage control, this BMS is ideal for both hobbyists and professionals looking to enhance their battery-powered projects. ## Description 1) high-accuracy voltage detection circuit; 2) terminal of the charger using high voltage device; 3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit); 4) MOS transistor can control the battery charge and discharge; 5) low standby current consumption. Brief Parameter: Over Charge voltage:4.25-4.35v±0.05v Over Discharge voltage: 2.3-3.0v±0.05v Max Working current:40A Max peak current:35-40A Working temperature:-40---+50 Storage Temperature:-40-- +80 Small current:50uA Life cycle: more then 30000 hours Resistance: Less than 100mΩ Short Cut: Protectable, Charge can repair Size:55*41*1.4mm Application: Vacuum cleaner, massager battery pack, LED backup power supply,12V li-ion electronics, solar power led, etc. 3 Series 18650 battery 11.1V (Li-ion 18650 or li-ion battery rated voltage) 11.1V (Li-ion battery full charge voltage) 12.6V.The lithium battery protection board is not included the welding tabs. BMS activate method : Use 12.6V Li-ion charger to change it. NOTE: 1) This board is not suit high power electronics is not suitedshigh-power driver and drill, electric bikescrewdriverke, fishing machine, and 1W LED, please don't buy this. 2)Above 3A device, means the battery discharge rate is more than 3C. 1C rated battery, 2000mah equals 2ah*1=2A max working current. 3C rated battery means 2ahx3=6A Max working current. The balancer is just an Auxiliary function, The balancing means when the battery is charging, each series battery needs with the same voltage. when ONE cell voltage gets 4.2V, the other cells do not, the first cell voltage will discharge to wait for the other cells rising to the same level. Note: battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma ## Features - 3S 11.1V 12.6V 40A 18650 lithium battery protection board (comes with recovery function-AUTO Recovery) - ELBOTICS Once all connections are done between battery pack and BMS, please give a initial charge to the battery pack first to activate the BMS. - Number of Cells: 3, Working Current: 20A, Peak Current: 40A - Over Discharge Voltage Range: 2.5-3.0V ± 0.05V - Over Charge Voltage Range: 4.25-4.35V ± 0.05V ## Images ![ELBOTICS® 3S BMS 40A 11.1V 12.6V 18650 Lithium ion Battery BMS PCM Battery Protection Board BMS PCM With Balance For Li-ion Battery Cell Pack Circuit Module - Image 1](https://m.media-amazon.com/images/I/61-5QJf37mL.jpg) ![ELBOTICS® 3S BMS 40A 11.1V 12.6V 18650 Lithium ion Battery BMS PCM Battery Protection Board BMS PCM With Balance For Li-ion Battery Cell Pack Circuit Module - Image 2](https://m.media-amazon.com/images/I/71tB-mUSKyL.jpg) ![ELBOTICS® 3S BMS 40A 11.1V 12.6V 18650 Lithium ion Battery BMS PCM Battery Protection Board BMS PCM With Balance For Li-ion Battery Cell Pack Circuit Module - Image 3](https://m.media-amazon.com/images/I/61DYS25ikgL.jpg) ![ELBOTICS® 3S BMS 40A 11.1V 12.6V 18650 Lithium ion Battery BMS PCM Battery Protection Board BMS PCM With Balance For Li-ion Battery Cell Pack Circuit Module - Image 4](https://m.media-amazon.com/images/I/71DEPp1juUL.jpg) ![ELBOTICS® 3S BMS 40A 11.1V 12.6V 18650 Lithium ion Battery BMS PCM Battery Protection Board BMS PCM With Balance For Li-ion Battery Cell Pack Circuit Module - Image 5](https://m.media-amazon.com/images/I/71Z7QQ13gSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Working fine *by S***A on Reviewed in India on 20 October 2022* Very good product.short circuit protection.over charge and discharge protection . ### ⭐⭐ गुणवत्ता सही नहीं है। *by A***R on Reviewed in India on 30 August 2022* यह BMS battery को ८ Volt तक पहुँचने के बाद बंद करता है, जबकी उसे १० Volt पर हि रोक लेना चाहिए। ### ⭐ This is problem *by V***U on Reviewed in India on 25 October 2022* only 9.6 v dc power output the BMS --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/373220283-elbotics-3s-bms-40a-11-1v-12-6v-18650-lithium](https://www.desertcart.tn/products/373220283-elbotics-3s-bms-40a-11-1v-12-6v-18650-lithium) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
