Trigger mode: low level trigger (ground) - β˜… 4 in 1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module. Lithium battery protection function: over-current, overvoltage, over-temperature, short circuit protection - β˜… In discharge mode (The charging mode KEY function is invalid), trigger the KEY port once to open the output; continuously trigger the KEY port twice to close the output - β˜… The first time the load is connected, the output is automatically turned on. If the load is less than 50mA, the output will be automatically turned off after 30 seconds; if the load is greater than 50mA, the output will be automatically turned on - β˜… Allow discharge while charging. (Note: At this time output voltage 4.7 / 5V) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PZT3ZW2 | | Best Sellers Rank | #232,605 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #961 in Power Converters | | Brand | MakerFocus | | Color | As Shown | | Customer Reviews | 4.3 4.3 out of 5 stars (246) | | Input Voltage | 5 Volts | | Item Dimensions | 0.98 x 0.63 x 0.39 inches | | Manufacturer | MakerFocus | | Mfr Part Number | 1468720264RM7BC61XM | | Output Voltage | 5 Volts | | Plug Type | Type B | | Power Source | rechargeable battery | | UPC | 673400168474 | | Unit Count | 6.0 Count | ## Product Details - **Brand:** MakerFocus - **Color:** As Shown - **Input Voltage:** 5 Volts - **Item dimensions L x W x H:** 0.98 x 0.63 x 0.39 inches - **Output Voltage:** 5 Volts ## Images ![6pcs 2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery with Charging Boost Mobile Power Protection PCB Board Module - Image 1](https://m.media-amazon.com/images/I/71PNAdxzBHL.jpg) ## Frequently Bought Together - 6pcs 2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery Charging Boost Mobile Power Protection PCB Board Module - HiLetgo 10pcs 18650 Battery Clip 18650 Battery Holder 18650 Batteries Case for 18650 Battery with Connect Lead - DWEII 10PCS Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board LED Display USB for DIY Charger (no Welding Version) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/125427065-6pcs-2a-5v-charge-discharge-integrated-module-3-7v-4](https://www.desertcart.ie/products/125427065-6pcs-2a-5v-charge-discharge-integrated-module-3-7v-4) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-07-10*
