It features a high equalizing current of up to 5.5A, ultra-low internal resistance MOSFETs, and a smart sleep mode that protects batteries by shutting down below 3V. Housed in a protective case you assemble yourself, it optimizes battery pack balance, enhances charging efficiency, and extends battery lifespan for capacities between 60-300AH. ## Description Product Describtion:Model:3S-4SSuitable :Lithium Iron Phosphate, NCM Ternary Polymer,(Not Fit Lithium Titanate)Voltage is 1.8 V-4.5VQuiescent Current: 12mASuggest Battery Capacity: 60-300AHWorking Temperature :0-60 degreesSleep Protection:voltage<3V, enter the sleep,standby power consumption is less than 0.1mA,to reduce the damage to the battery.Safety Information：Before connecting the equalization board, check whether each piece of wiring is correct, and do insulation work to prevent burnout,This is very important, please pay attention.NOTE: If the LED indicator is always on, it means that the capacitor plate has been running in a balanced manner. When a fault occurs, the LED indicator will go out.Package Included:1*3S 4S 5A Active Equalizer Lifepo4 Lipo Lto Lithium1*Protective Case ## Features - [Product Information]: Protective Case needs to be assembled by yourself,After the assembly is completed, tear off the outer yellow film.Before connecting the equalization board, check whether each piece of wiring is correct, insulation between the bottom board and the battery connection terminals is required to prevent burnout.Model:3S-4S Suitable : Lithium Iron Phosphate, NCM Ternary Polymer,(Not Fit Lithium Titanate). - [Capacitance Principle]: No external power supply is required,The working principle is Capacitor fit transfers the charge transporter, use the internal energy transfer of the battery to transfer and balance the entire battery pack.the equalization board can be connected to the battery to start the equalization work. - [Protection switch]: With sleep protection, when the voltage is lower than 3V, it will automatically stop and enter the sleep state to reduce the damage to the battery.With a protective case, it can better protect 3S 4S 5A Active Equalizer and Extend product life. - [Original Design]:using the original ultra-low internal resistance MOS, 2OZ copper thickness PCB, equalizing current 0-5.5A, The more balanced the battery, the lower the current.Voltage is 1.8 V-4.5V ,Suggest Battery Capacity: 60-300AH. - [Satisfactory service]:Protective Case needs to be assembled by yourself, We Provide 24-hour online service,If you encounter any problems, Please email SELLER SUPPORT (Not desertcart support), we will give you a perfect solution. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09QKWH6RL | | Best Sellers Rank | #242,019 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,011 in Power Converters | | Brand | Cywhrvzsf | | Color | Yellow | | Customer Reviews | 4.5 out of 5 stars 122 Reviews | | Input Voltage | 18 volts_of_direct_current | | Item Weight | 0.1 kg | | Manufacturer | Cywhrvzsf | | Mfr Part Number | yun-dong-199 | | Model Number | 3S-4S | | Number of Items | 2 | | Output Voltage | 18 volts_of_direct_current | | UPC | 602262884062 | | Unit Count | 1 Count | ## Product Details - **Brand:** Cywhrvzsf - **Color:** Yellow - **Item Weight:** 0.1 Kilograms - **Input Voltage:** 18 Volts (DC) - **Output Voltage:** 18 Volts (DC) ## Images ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - Image 1](https://m.media-amazon.com/images/I/718cWBy4tDL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - Image 2](https://m.media-amazon.com/images/I/61rMj+C93IL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - Image 3](https://m.media-amazon.com/images/I/61G3deNlbFL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - Image 4](https://m.media-amazon.com/images/I/71gC2DZNY5L.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - Image 5](https://m.media-amazon.com/images/I/61-+SG9grBL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - 3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Protective Case - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - ILL Customz 38120 Headway Buss Bars 4s Configuration for 12v Cells NOT Included (48ah 4s6p (24 Cells)) --- ## 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.com.sa/products/409082227-3s-4s-5a-active-equalizer-whole-group-balancer-lifepo4-lipo](https://www.desertcart.com.sa/products/409082227-3s-4s-5a-active-equalizer-whole-group-balancer-lifepo4-lipo) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-10-10*
