DALY BMS Li-ion 7S 24V 20A BMS Battery Management System for 18650 Battery Pack Balanced Charging Board

The DALY 24V 7S 20A BMS is a premium and reliable Battery Management System designed for 7S (7-series) 24V Lithium-ion battery packs. Featuring a balance wire and an advanced temperature sensor, it ensures safe charging and discharging, stable performance, and extended battery lifespan. With complete protection against overcharge, over-discharge, short-circuit, overcurrent, and extreme temperatures, this BMS helps you build long-lasting and secure lithium battery solutions. Note: This model is compatible only with 7S 24V Lithium-ion packs — not LiFePO4, Li-Metal, or LTO batteries.

Its intelligent balancing function keeps each cell at equal voltage, preventing voltage differences that lead to premature cell failure. Perfect for DIY battery pack builders, solar storage systems, EV projects, and portable energy solutions.
