Balanced version: Suitable for starting currents below 25A and below 50W power drills,or resistive loads below 168W,with balanced Futures Color:green Charging voltage:8.4V - 9.0V Material:ABS and metal Product Size: 48*20*3.4mm (Balancing) Package Contents 5pcs * 2S 20A Lithium Battery 18650 Charger PCB BMS Board Review: Nice small board - Did what I expected. During one of my tests, the charging voltage reached 8.5V using a 9V/5A power supply. No dramatic heat dissipation observed, the maximum charging current reaches 2A for dual 3500mah batteries. Discharging works great for small loads under 5A without any issues. Review: work fine - These little charging pcbs do work, but they dont come with any diagrams or information in how to connect them. I have one in a small rc car thats running on 2) 112245 3.7v lipo cells out of some disposable vapes in series connected to one of these balance charge modules. I am using a 9v usb-c pd trigger board for an input and regulating the output back down to 5v with a small buck converter. It seems to work just fine for this setup. ## Features - 100% brand new and high quality - Charging voltage:8.4V-9.0V - Continuous charge current(upper limit):10A - Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions) Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NSTF8CT | | Amperage | 10 Amps | | Brand | AITRIP | | Color | 5 PCS 2S 20A with Balance | | Connector Type Used on Cable | US Power Plug | | Current Rating | 10 Amps | | Customer Reviews | 4.0 out of 5 stars 40 Reviews | | Input Voltage | 9 Volts | | Item Dimensions D x W x H | 0.13"D x 0.13"H | | Manufacturer | AITRIP | | Mfr Part Number | EC1691647 | | Number of Ports | 1 | | Output Voltage | 8.4 Volts (DC) | | Product Dimensions | 0.13"D x 0.13"H | | UPC | 701715453951 | ## Product Details - **Brand:** AITRIP - **Color:** 5 PCS 2S 20A with Balance - **Product Dimensions:** 0.13"D x 0.13"H - **Output Voltage:** 8.4 Volts (DC) - **Input Voltage:** 9 Volts ## Images ![5 PCS 2S 20A 7.4V 8.4V 18650 Li-Ion Lithium Battery 18650 Charger PCB BMS Board with Balance - Image 1](https://m.media-amazon.com/images/I/81fcbrzhODL.jpg) ![5 PCS 2S 20A 7.4V 8.4V 18650 Li-Ion Lithium Battery 18650 Charger PCB BMS Board with Balance - Image 2](https://m.media-amazon.com/images/I/71dz9PpIDdL.jpg) ![5 PCS 2S 20A 7.4V 8.4V 18650 Li-Ion Lithium Battery 18650 Charger PCB BMS Board with Balance - Image 3](https://m.media-amazon.com/images/I/7145aac9+qL.jpg) ![5 PCS 2S 20A 7.4V 8.4V 18650 Li-Ion Lithium Battery 18650 Charger PCB BMS Board with Balance - Image 4](https://m.media-amazon.com/images/I/71xFbKYxZCL.jpg) ![5 PCS 2S 20A 7.4V 8.4V 18650 Li-Ion Lithium Battery 18650 Charger PCB BMS Board with Balance - Image 5](https://m.media-amazon.com/images/I/71neHi8cQvL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice small board *by F***X on November 17, 2025* Did what I expected.
