Featuring a durable 2OZ copper PCB and ultra-low resistance MOSFETs, it optimizes battery health while consuming less than 0.1mA in sleep mode. Its smart under-voltage protection safeguards cells by pausing operation below 2.7V, making it ideal for 30-200AH battery packs seeking enhanced lifespan and performance. ## Description Capacitor energy transfer balance board with Balance cable (upgraded version, 5mv high precision, whole group balance, not adjacent balance) Technical Parameters: Working voltage: 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4). 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 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. 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. Board size: 66x35x16mm/2.6x1.37x0.63inch 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+, ... B3+.(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 3S Balancer Board 1x 4-Pin Cable ## 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. - 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. - 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. ## Product Details - **Brand:** QINIZX - **Color:** Green - **Item Weight:** 2 Ounces - **Item dimensions L x W x H:** 2.58 x 1.36 x 0.62 inches - **Output Voltage:** 12 Volts ## Images ![5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board Active Balance Equalization Module Capacitor Whole Group Balancer w/Silicone Cable - Image 1](https://m.media-amazon.com/images/I/51BYS9nQH3L.jpg) ![5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board Active Balance Equalization Module Capacitor Whole Group Balancer w/Silicone Cable - Image 2](https://m.media-amazon.com/images/I/61Y09N0xhaL.jpg) ![5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board Active Balance Equalization Module Capacitor Whole Group Balancer w/Silicone Cable - Image 3](https://m.media-amazon.com/images/I/61SzrO5iUlL.jpg) ![5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board Active Balance Equalization Module Capacitor Whole Group Balancer w/Silicone Cable - Image 4](https://m.media-amazon.com/images/I/61lkbpjRGnL.jpg) ![5A 3S 12V 12.6V Battery Active Equalizer BMS Balancer LFP Lifepo4 Lithium Lipo Li-ion Battery Energy Transfer Board Active Balance Equalization Module Capacitor Whole Group Balancer w/Silicone Cable - Image 5](https://m.media-amazon.com/images/I/51OdqIelgvL.jpg) ## Available Options This product comes in different **Size** options. --- ## 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.pe/products/375911655-5a-3s-12v-12-6v-battery-active-equalizer-bms-balancer](https://www.desertcart.pe/products/375911655-5a-3s-12v-12-6v-battery-active-equalizer-bms-balancer) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-25*
