Featuring ultra-low resistance MOSFETs and a thick copper PCB, it ensures efficient energy transfer and long-term reliability. With under-voltage sleep protection and minimal standby current (<0.1mA), it safeguards battery health while optimizing performance. Ideal for 30-200AH battery packs, this module is a must-have for professionals demanding consistent, balanced power. ## Description Product description Working voltage: 1.8V-4.5V Suitable for ternary lithium(Li-ion), lithium iron phosphate (LiFePO4), lithium titanate(LTO). The whole battery participates in the active equalization of energy transfer at the same time. 0.1V differential voltage 1A equalizing current. The differential voltage is bigger that equalizing current is bigger. The maximum allowable working current is 5.5A. Working principle: Flycap-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 manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv! The quiescent current is about 7mA, and the battery capacity is recommended to be used between 30-200AH/Per Balancer. With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA. Board size: 69x58x16mm/ 2.71x2.28x0.63inch Balance cable length: 400mm/ 15.7inch One LED indicator: It will always be on during normal operation, but it will not turn on when there is a problem or malfunction. RUN pad: you can add a switch to control the balancer. Default short connect, let balancer working. if disconnect, it will not working. Note: 1. Please start wiring from the total negative pole, followed by B-, B1+, B2+, ... B5+.(Test per string battery voltage whether is right before connect to Balancer board). 2. The time required for equalization mainly depends on the battery capacity. It is normal for the capacitor to heat up during energy conversion. Package Includes: 1x 5S Balancer Board with 6-pin Cable Safety Warning Buyers need to have a certain basic knowledge of electronics and related hands-on skills. Review: I'm sold. These little guys just work. Latest build is a 4S2P 12v LIFEPO4 and the cells have been as much as .20 out of balance while charging. Within a couple hours they are exactly the same. I've read some horror stories with these and the main thing to.prevent problems is to install these before the battery pack is a mess of mismatched voltages. Review: Balanced like a champ for 10 minutes after I got it installed on a 16S LiFePO4 pack. Would be a great unit, if it didn't let the smoke out and stop functioning. ## Features - Working Voltage: 1.8V-4.5V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4),lithium titanate battery (LTO). Tips: The voltage gap of each cell of the battery pack is controlled within 0.5V. NOTE that It takes time to equalize the voltage, and it does not take effect immediately after plugging it in. - 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 7mA, 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 B1 battery voltage, the equalizer will automatically stop entering the sleep state when the B1 voltage NCM/LFP<2.7V or LTO<1.8V, and the standby power consumption is <0.1mA.Board size 2.71x2.28x0.63inch; Balance cable length 15.7inch. - Usage Tips: 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: If it used for 4S, the last line B5+ is empty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09DBG2Z6P | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 41,209 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 880 in International Power Adapters | | Colour | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (169) | | Date First Available | 5 Jun. 2021 | | Included components | PCBA+Cable | | Item Package Quantity | 1 | | Item Weight | 56.6 g | | Item model number | JW-CAP-Balancer-5S | | Manufacturer | QINIZX | | Part number | JW-CAP-Balancer-5S | | Plug format | 2 Pin | | Power source type | DC | | Product Dimensions | 6.91 x 5.82 x 1.63 cm; 56.7 g | | Size | 4S-5S | | Voltage | 21 Volts (DC) | ## Product Details - **Brand:** QINIZX - **Colour:** Black - **Input voltage:** 4.5 Volts (DC) - **Item dimensions L x W x H:** 6.9 x 5.8 x 1.6 centimetres - **Item weight:** 2 Ounces ## Images ![4S 5S 5A Active Equalizer Balancer LFP Lifepo4 Lithium Lipo/Titanate LTO Battery Energy Transfer Board Active Equalization Module Capacitor Faster Whole Group Balancer - Image 1](https://m.media-amazon.com/images/I/61kWJdioBtL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***S on 4 November 2025* I'm sold.

Would be a great unit, if it didn't let the smoke out and stop functioning. ### ⭐⭐⭐⭐⭐ Review *by I***D on 30 July 2025* I found this battery balancer very useful and effective. I used it daily for months, but it died due to my error. Please triple-check the battery pack's resistance. I failed to notice a dead battery with high resistance, and the capacitor exploded and melted my silicone mat. The photo shows the melted area on my mat. ## Frequently Bought Together - 4S 5S 5A Active Equalizer Balancer LFP Lifepo4 Lithium Lipo/Titanate LTO Battery Energy Transfer Board Active Equalization Module Capacitor Faster Whole Group Balancer - 16S 48V 60V 1.2A Li-ion Lipo Lifepo4 LFP Battery Active Equalizer BMS Balancer Inductive Balance Lithium Battery Energy Transfer Board (16S) - 3S 4S 5A Active Equalizer Whole Group Balancer Lifepo4 Lipo Lto Lithium Active Battery Energy Transfer Equalization Capacitor --- ## 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.hr/products/502109861-4s-5s-5a-active-equalizer-balancer-lfp-lifepo4-lithium-lipo](https://www.desertcart.hr/products/502109861-4s-5s-5a-active-equalizer-balancer-lfp-lifepo4-lithium-lipo) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
