China unveils Dragon Armor 3.0 battery with world-first fire-energy separation design

• Dragon Armor 3.0 introduces world‑first fire‑energy separation in Li‑ion batteries. • Physical isolation of terminals from pressure relief channels reduces thermal runaway risk.

Build a practical 400 mA linear Li-ion charger with visible CC-CV behavior

• Linear Li‑ion charger delivers 400 mA constant current from a 5 V supply, then switches to 4.217 V constant voltage. • Dual‑loop control uses a PNP pass transistor, with inner cu
