3S 5A Li-ion/NMC Smart Battery Management with Balance, Temperature, Overcharge & Overcurrent Protection

Building a 3S battery pack without a BMS is like driving without brakes — the amiciKart 3S 5A Smart BMS gives your Li-ion/NMC cells the intelligent protection they need to stay safe, balanced, and long-lasting.

This compact BMS module is engineered specifically for 3-cell (3S) Li-ion and NMC battery packs operating in the 11.1V–12.6V range. It delivers a comprehensive safety net: overcharge protection kicks in at 4.25V per cell, over-discharge cuts off at 2.5V, and overcurrent protection handles surges up to 15A — all with intelligent delay control to avoid nuisance trips. The built-in NTC thermal sensor automatically cuts charging above 50°C and discharging above 70°C, protecting your cells from heat damage in demanding environments.

What sets this module apart is its same-port MOSFET design with automatic cell balancing — it equalises voltage across all three cells to maximise cycle life and pack capacity, while keeping your wiring clean and compact (just 60×30×50mm, 12g). Whether you're building a DIY power bank, a solar storage unit, a portable speaker, or an e-bike auxiliary pack, this BMS integrates seamlessly into tight enclosures with minimal fuss.

Ideal for electronics hobbyists, engineers, and makers across India who demand reliable, professional-grade battery protection without the premium price tag. Backed by a 1-year warranty and real Indian seller support from amiciKart — call 980 970 9898 or email care@amicikart.com anytime. In stock now with same-day dispatch for orders before 2 PM. ✅
