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*Test Board Review: Good for KS2 Corp battery packs - These work well. I had KS2 corp lithium battery packs in my RV, one of which was failing. Managed to get it working fine again by adding one of these. Review: Works great - Works great ## 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 | B0BYFB7YY9 | | Best Sellers Rank | #352,194 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #38,195 in Electrical Equipment | | Brand | Cywhrvzsf | | Color | black | | Customer Reviews | 4.6 out of 5 stars 16 Reviews | | Input Voltage | 4.5 volts | | Manufacturer | Cywhrvzsf | | Model Number | 3S-4S | | Number of Items | 1 | | Output Voltage | 4.5 volts | | Plug Format | Type A | | Plug Type | Type A | | Warranty Description | 1YEAR | ## Product Details - **Brand:** Cywhrvzsf - **Color:** black - **Input Voltage:** 4.5 Volts - **Output Voltage:** 4.5 Volts - **Plug Format:** Type A ## Images ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Test Board - Image 1](https://m.media-amazon.com/images/I/71-B+225MKL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Test Board - Image 2](https://m.media-amazon.com/images/I/6136lsyuBdL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Test Board - Image 3](https://m.media-amazon.com/images/I/71bE5VoWH6L.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Test Board - Image 4](https://m.media-amazon.com/images/I/71h-fJ2DwHL.jpg) ![3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor + Test Board - Image 5](https://m.media-amazon.com/images/I/71ePZ3IUETL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good for KS2 Corp battery packs *by J***K on March 7, 2026* These work well.
