TDT Li-ion NMC 7S 25.9V 20A Battery Management System

For more demanding applications, this 7-series (25.9 V) NMC lithium-ion BMS steps up with a 20 A continuous discharge rating. Ideal for high-torque e-bikes, lightweight EVs, and energy storage systems, it preserves the full suite of hardware safety: over/under-voltage, overcurrent, short-circuit, and thermal protections. Passive balancing keeps cells uniform, and a reserved discharge switch eases system control. Its low-power idle draw and compact 60×35×10 mm size make it a smart, efficient choice. Parallel support enables expansion, and the higher current capacity ensures you get more performance while staying protected.
