3S Active Balancer Inductive Board for High Precision Smart Cell Voltage Equalizer LiFePO4 Lithium-ion LTO Battery Packs (1.2A)

Tired of unbalanced battery cells killing your pack's performance and lifespan? The amiciKart 3S Active Balancer Inductive Board intelligently redistributes energy across all three cells — keeping your battery pack healthy, efficient, and long-lasting.

This high-precision active balancing board uses inductive energy transfer to equalise cell voltages within a tight 30mV tolerance, far superior to passive balancers that simply waste excess energy as heat. With adaptive current output ranging from 0.5A for minor imbalances up to 1.2A for larger gaps, the board restores cell uniformity quickly without stressing the pack. Its smart logic activates automatically when voltage difference exceeds 0.1V and gracefully stops below 0.03V — preventing over-correction and unnecessary energy drain. An auto-dormant mode kicks in once cells are balanced, keeping standby losses near zero.

Built for universal chemistry support, this board works seamlessly with LiFePO4, Lithium-ion, LTO, NMC, LFP, and Ternary Lithium packs operating between 3.0V and 4.2V per cell. Whether you're building a solar storage system, upgrading an electric vehicle pack, or working on a custom DIY battery project, this balancer delivers professional-grade precision at an accessible price point.

Sold by amiciKart — a trusted Indian electronics brand — this board is backed by a 1-year warranty with dedicated support. Order before 2 PM for same-day dispatch, with free shipping across India and Cash on Delivery available.

• Maximise Battery Lifespan with 30mV Precision – high-precision balancing keeps all 3 cell voltages within 30mV of each other, preventing premature capacity fade and extending overall pack life
