3S 2A Active Energy Balancer Board – Inductive Voltage Energy Equalization for LiFePO4 / Li-ion / Lipo / LTO Battery Packs (3.0V–4.2V)

Unbalanced cells are silently killing your battery pack — the 3S 2A Active Energy Balancer Board fixes that with intelligent inductive equalization, extending your pack's life and maximising every charge cycle.

This Active Balancer Board uses high-efficiency inductive energy transfer to redistribute charge from stronger cells to weaker ones — not waste it as heat like old-school passive balancers. It auto-triggers the moment a voltage difference of just 20mV (±5mV) is detected across any cell, delivering up to 2A of balancing current to bring your pack back into harmony. With a standby draw of only 15µA, it stays vigilant without draining your battery. Compatible with LiFePO4, LFP, LTO, Li-ion, and LiPo chemistries across a 3.0V–4.2V per-cell range, this board is a true all-rounder for any 3-series pack.

Whether you're building a DIY solar storage system, assembling an e-bike battery, powering a home UPS, or prototyping an EV module — this board ensures every cell in your 3S pack operates within its optimal voltage window. It prevents premature wear, eliminates overcharge hotspots, and delivers measurably better pack stability over hundreds of cycles. Rated for -15°C to 65°C and 10%–70% RH, it handles everything from rooftop solar installations to workshop benches without complaint.

Sold by amiciKart — a trusted Indian electronics brand — this board ships with a 1-year warranty, free shipping across India, same-day dispatch on orders before 2 PM, and Cash on Delivery available. Store pickup is also available at Noida. Build smarter. Balance better.

• Extend battery pack lifespan with high-efficiency inductive energy transfer — redistributes charge from stronger cells to weaker ones, up to 20x more efficient than passive balancers (2A max balance current)
• Precision auto-balancing triggers at just ≥20mV voltage difference (±5mV accuracy), keeping every cell in your 3S pack within optimal voltage range without manual intervention
• Ultra-low standby consumption of only 15uA during balancing — won't silently drain your pack between cycles, preserving usable battery capacity over the long term
• Wide chemistry compatibility works seamlessly with LiFePO4, LFP, Li-ion, LiPo, and LTO cells (3.0V–4.2V per cell), making it ideal for EVs, solar storage, and DIY power projects
• Built for Indian conditions — operates reliably across -15°C to 65°C and 10%–70% RH, suitable for rooftop solar setups, vehicle battery packs, and workshop environments
• Shop with confidence: 1-year warranty backed by amiciKart, 30-day no-questions-asked returns, COD available, and free pan-India shipping with same-day dispatch on orders before 2 PM
