4S 2A Active Energy Balancer Board – Inductive Voltage Energy Equalization for LiFePO4 / Li-ion / Lipo / LTO Battery Packs (2.8V–4.2V)

Tired of unbalanced battery cells killing your pack's performance and lifespan? The amiciKart 4S 2A Active Energy Balancer Board uses advanced inductive energy transfer to keep every cell in perfect harmony — so your battery pack lasts longer, charges smarter, and delivers consistent power every time.

Unlike traditional passive balancers that simply burn off excess charge as heat, this active balancer moves energy from higher-voltage cells to lower ones using high-efficiency inductive transfer. The result: zero wasted capacity, minimal heat generation, and a dramatically healthier battery pack. It automatically kicks in when any two cells drift beyond 45mV (±15mV), drawing just 5μA during balancing — so it's always on guard without draining your pack. Compatible with LiFePO4, LFP, LTO, Li-ion, and LiPo chemistries (2.8V–4.2V per cell), it works reliably across a wide temperature range of -15°C to 65°C and 10%–70% RH, making it suitable for both indoor and outdoor installations.

Whether you're building a DIY solar storage system, powering cordless tools, assembling an e-bike battery, or setting up an off-grid energy bank, this board is the upgrade your 4S pack deserves. It's a plug-and-play solution designed for hobbyists, engineers, and solar enthusiasts across India who demand precision and reliability from their lithium battery setups.

Backed by a 1-year warranty from amiciKart and available with Free Shipping across India, same-day dispatch (orders before 2 PM), and Cash on Delivery — getting the best out of your battery pack has never been easier.
