Operating without external power, it actively balances cells with up to 5.5A current, features smart sleep protection below 3V to safeguard battery health, and is built with premium 2OZ copper PCB and ultra-low resistance MOSFETs for durability and efficiency. Ideal for professionals seeking reliable, maintenance-free battery optimization. ## Description Product Describtion: Model:3S-4S Suitable : Lithium Iron Phosphate, NCM Ternary Polymer,(Not Fit Lithium Titanate)Voltage is 1.8 V-4.5V Quiescent Current: 12mA Suggest Battery Capacity: 60-300AH Working Temperature :-20 degrees to +60 degrees Sleep 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 Lithium Review: low consumption - Very good balancer, low consumption and works perfectly Review: Works great! - I really like this active equalizer board. Keeps the cells within 1mv of each other. Using it with a 100 AH battery. This does not have a current limiter or over voltage control as a BMS does, But in my case, works better. All I needed was a balance unit and this one is just what I was looking for. ## Features - [Product Information]: 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) ,Voltage is 1.8 V-4.5V ,Suggest Battery Capacity: 60-300AH. - [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. - [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. - [Satisfactory Service]: 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 | B09G74WDN5 | | Brand Name | Cywhrvzsf | | Customer Reviews | 4.4 4.4 out of 5 stars (109) | | Item Shape | Round | | Item Weight | 2.39 Ounces | | Manufacturer | Cywhrvzsf | | Material Type | Polymer | | Maximum Storage Temperature | 60 Degrees Celsius | | Maximum Voltage | 4.5 Volts | | Mounting Type | Flush Mount | | Operating Voltage | 4.5 Volts | | UPC | 602262884017 | | Upper Temperature Rating | 60 Degrees Celsius | ## Product Details - **Brand:** Cywhrvzsf - **Material:** Polymer - **Maximum Storage Temperature:** 60 Degrees Celsius - **Operating Voltage:** 4.5 Volts - **Shape:** Round ## Images ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor - Image 1](https://m.media-amazon.com/images/I/610qoggrzNL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ low consumption *by J***A on May 30, 2025* Very good balancer, low consumption and works perfectly ### ⭐⭐⭐⭐⭐ Works great! *by T***D on December 19, 2024* I really like this active equalizer board.
