20S 2Amps Active Balancer Equalizer for Lithium Battery Pack
[Lithium Battery Protection Board] The NEEY 20S 2A Active Balancer Equalizer is an intelligent battery balancing module designed for 20 series Lithium battery packs. It uses active energy transfer technology to redistribute energy from higher-voltage cells to lower-voltage cells, ensuring the entire battery pack remains balanced during operation. Unlike passive balancers that dissipate excess energy as heat, this active balancing system transfers energy between cells, improving battery efficiency, performance, and lifespan. With up to 2A balancing current, the module quickly corrects voltage differences between cells, preventing issues such as cell overcharge, deep discharge, and imbalance. This makes it ideal for solar energy storage systems, electric vehicles, DIY battery packs, power walls, and industrial energy storage solutions. The NEEY active balancer provides reliable and efficient balancing to maintain stable battery pack performance in demanding applications. 🔹 Key Features Supports upto 20S Lithium battery packs Active energy transfer balancing technology Maximum 2A balancing current Improves battery efficiency and lifespan Reduces cell voltage imbalance Low heat generation compared to passive balancing Stable operation across wide temperature range Easy installation with long balance wires 🔹 Technical Specifications Parameter Specification Brand / Model NEEY 20S2A Battery Type Lithium Battery Strings 20S Balancing Method Active Balancing Maximum Balance Current 2A Operating Voltage Range 2.8V – 3.65V per cell Adjacent Cell Difference ≥0.1V (0.5–0.7A balancing) Maximum Balance Current 2A when voltage difference ≥0.2V Working Temperature -20°C to 60°C 🔹 Product Dimensions Size: 95 × 92 × 8 mm Weight: 135 g Balance Wire Length: 60 cm 🔹 Applications Solar energy storage systems LiFePO4 battery packs Electric vehicles (EV) E-bikes and electric scooters Energy storage systems (ESS) DIY lithium battery packs Industrial power systems 🔹 Package Includes 1 × NEEY 20S 2A Active Balancer Unit 1 × Balance Wire Harness (60 cm)

[Lithium Battery Protection Board] An active balancer or equilizer, balance you cells all the time during discharge and charge and maintain same voltage level along with the whole battery, Provides a lot better back up and mileage than a normal battery pack. Connect the balancer along with the bms Module. Balancer does not do work of BMS, make sure BMS and balancer both are different. Balancer make battery balance and give more back up and mileage, and helps your battery to maintain the long life. You can use this balancer to Any ah battery like 12ah, 18ah or 50ah 100ah etc. Balancer Specification – Suitable – 19S LifePO4 48volt Operating voltage range: 2.8v to 3.65volt Balance current: 2Amps Max Adjacent voltage difference is 0.1V or more (current is about 0.5-0.7A); Adjacent voltage difference is above 0.2V (maximum balance current is 2A); The smaller the differential voltage, the smaller the balance current. other Info Product Dimensions – 92 x 85 x 8 mm Item Weight – 122grm Wire length – 60cm Package Include – 1. Balancer Unit 2. Balancer Wires
16s 2Amps Active Balancer Equalizer for NCM/LFP Battery
[Lithium Battery Protection Board] The 16S2A Active Balancer (NEEY) is a battery management solution designed for 16 series lithium-based battery packs. It supports 2A of current per cell for active balancing, which helps ensure that all cells in the battery pack are charged to the same voltage level. Active balancing optimizes battery performance by redistributing energy from higher-voltage cells to lower-voltage cells, thus improving the overall efficiency and lifespan of the battery pack. This balancer helps to prevent overcharging or deep discharging of individual cells, ensuring a safer and more reliable operation. The NEEY designation indicates the specific brand or model, offering efficient and effective cell balancing for applications such as energy storage systems, electric vehicles, and other lithium-based power solutions. Balancer Specification – Suitable – 16S 48volt Applicable battery type : NCM/LFP Teemary Lithium/Lithium Iron Single voltage working range: NCM/LFP version 3.0V-4.2V Balance method : Detect the nearby voltage difference is greater than 0.1V totrigger the start of balanced the adjacent battery voltage difference is less than 003V to stop working Balance current: 0.2V Adjacent voltage difference 0.1V, Balance current: 054-0.74, Adjacent voltage difference 0.2V. Balance current: 2A LED indicator : 1. When the equalization light is on the equalization work is turned on, 2. The equalization light goes out the equalization circuit sleeps Operating Temperature Range: -20° to 60° The smaller the differential voltage, the smaller the balance current. package Include – 1.
