Featuring ultra-low resistance MOSFETs and a thick copper PCB, it delivers up to 5.5A balancing current with exceptional voltage accuracy (±5mV). Its intelligent under-voltage sleep protection minimizes power loss (<0.1mA), making it ideal for professional-grade battery management in scalable, high-capacity setups. ## Description 3S 4S 12V 5A Battery Active Equalizer BMS Balancer Lipo Li-ion LFP LiFePO4 Lithium Battery Balance Active Energy Transfer Equalization Module Faster Whole Group Capacitor Balancer PCB ## Features - Working Voltage: 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4). It can Not fit LTO battery. NOTE Tips: Well tested by the manufacturer. As long as the wiring is correct, the product guarantees long-lasting and effective performance. (Default Not include any batteries.) - Working Principle: 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! - The quiescent current is about 9mA, and the battery capacity is recommended to be used between 30-200AH/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. - NOTE: 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. Tips: This balancer board is backward compatible by default. eg. If it is used for 3S, the last line B4+ is empty. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | QINIZX | | Manufacturer | QINIZX | | Model | JW-CAP-Balancer-4S | | Product Dimensions | 6.63 x 4.57 x 1.6 cm; 50 g | | Item model number | JW-CAP-Balancer-4S | | Number of items | 1 | | Voltage | 16.8 Volts (DC) | | Power Source | DC | | Batteries Included | No | | Batteries Required | No | | Material | Copper | | Mounting Type | Flush Mount | | Manufacturer | QINIZX | | Country of Origin | USA | | Item Weight | 50 g | ## Product Details - **Brand:** QINIZX - **Colour:** Black - **Item dimensions L x W x H:** 6.6 x 4.6 x 1.6 Centimeters - **Plug Type:** Type A - **UPC:** 723258876141 ## Images ![3S 4S 12V 5A Battery Active Equalizer Lipo Li-ion LFP LiFePO4 BMS Balancer - Image 1](https://m.media-amazon.com/images/I/61Wv0GAAguL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can I use this with my 8s 24 volt battery pack??** A: yes, it must can use it. **Q: Will this damage sells in below freezing environments?** A: Working temperature: -10 degrees to +60 degrees **Q: Can i use this on headway 38120 8ah cells?** A: Yes, it can use it. **Q: Can the 13-17s be used for 2 individual 8s packs, one 8s on each harness side of balance board? ?** A: No, suggest buy two 8s model. ## Frequently Bought Together - 3S 4S 12V 5A Battery Active Equalizer BMS Balancer Lipo Li-ion LFP LiFePO4 Lithium Battery Balance Active Energy Transfer Equalization Module Faster Whole Group Capacitor Balancer PCB - 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.pl/products/559750554-3s-4s-12v-5a-battery-active-equalizer-lipo-li-ion](https://www.desertcart.pl/products/559750554-3s-4s-12v-5a-battery-active-equalizer-lipo-li-ion) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-10-20*
