Compatible with NCM ternary polymer, LiFePO4, and Li-ion batteries, it delivers precise balancing with up to 5.5A current and voltage accuracy within 5mV. Featuring ultra-low quiescent current (<0.1mA) and a user-friendly RUN pad switch with LED status indicator, this balancer optimizes battery lifespan and performance. Its robust 2OZ copper PCB and MOSFET components ensure durability, making it a must-have for professionals seeking efficient, reliable battery equalization. ## Description 1x 4S Balancer Board; 1x 5Pin Cable; 2 x Acrylic Board; 4 x Short Screw; 4 x Long Screw; 4 x Stud; 4 x Washer NOTE : This active balancer is not a BMS protection board, so no matter how bad the battery you use to test, it can be used, But it has no functions such as over-voltage, under-voltage, or over-current. A BMS is required to manage all those things. Suggest use it in parallel with the BMS protection board. ## Features - Wide Voltage Compatibility: Working Voltage 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4), Not Fit Lithium Titanate. It can be used in parallel with BMS protection board. The default protective case is a kit, not assembled, the transparent acrylic case has a yellow protective film that can be peeled off - Advanced Balancing Technology: Flying capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB. Balance current 0-5.5A, the more balanced the battery current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv - Efficient Power Management: The Quiescent Current is about 12mA, and the battery capacity is recommended to be used between 30-300AH/Per Balancer. High-capacity batteries can be connected in parallel with multiple equalizers. With under-voltage sleep protection, only detecting the battery voltage of B1, the equalizer will automatically stop entering the sleep state when the B1 voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA - User-Friendly Control Features: RUN Pad allows you to add a switch to control the balancer. Default short connect, let balancer working. if disconnect, it will not working. One LED indicator will always be on during normal operation, but it will not turn on when there is a problem or malfunction. Equipped with VH3.96 terminal by default, come with 1.31ft 18awg wire - Important Installation Guidelines: Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the battery pack are correct, and do a good job of insulating the bottom of the board and the battery string connection terminals. Otherwise, it will short-circuit and burn the board. This balancer board is backward compatible by default, if it is used for 3S, the last line B4+ is empty ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0BM77J1BQ | | Best Sellers Rank | #7,576 in Musical Instruments (See Top 100 in Musical Instruments) #3 in Equalizers & Feedback Controllers | | Brand | QINIZX | | Color | Yellow | | Customer Reviews | 4.6 4.6 out of 5 stars (282) 4.6 out of 5 stars | | Input Voltage | 12 volts | | Item Dimensions | 2.6 x 1.8 x 0.63 inches | | Item Highlight | Lifepo4 LFP Lipo Li-ion Lithium Compatible, Whole Group Balancer, Active Energy Transfer Equalization, Protective Case | | Item Weight | 2.88 ounces | | Manufacturer | QINIZX | | Mfr Part Number | Balancer-4S-5A-Shell | | Model Number | Balancer-4S-5A-Shell | | Number Of Items | 1 | | Number Of Outlets | 1 | | Number Of Packs | 1 | | Output Voltage | 16.8 volts | | Plug Type | VH3.96 Terminal | | Power Source | Battery-Powered | | Unit Count | 1 Count | | Upc | 780854489120 | | Warranty Description | 90 Days Manufacturer | ## Product Details - **Brand:** QINIZX - **Color:** Yellow - **Input Voltage:** 12 volts - **Item Weight:** 2.88 ounces - **Item dimensions L x W x H:** 2.6 x 1.8 x 0.63 inches ## Images ![3S 4S 12V 5.5A Battery Active Equalizer Balancer Energy Transfer Board - Image 1](https://m.media-amazon.com/images/I/712IHdA-MAL.jpg) ## Available Options This product comes in different **Set name** options. ## Frequently Bought Together - 3S 4S 12V 5.5A Capacitor Active Equalizer Whole Group Balancer Lifepo4 LFP Lipo Li-ion Lto Lithium Active Battery Energy Transfer Equalization + 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 - Heltec 4S 5S 6S 5A Capacitor Active Equalizer Balancer Lifepo4 Lithium Lipo/Titanate LTO for Battery Car Audio Group Balancer --- ## 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.es/products/502041409-3s-4s-12v-5-5a-battery-active-equalizer-balancer-energy](https://www.desertcart.es/products/502041409-3s-4s-12v-5-5a-battery-active-equalizer-balancer-energy) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-11-09*
