Overview

Over-charge, over-discharge and short protection, 4 A

The ET-P08 is built around the Over-charge ~4.3V, over-discharge ~2.4V, over-current/short (DW01+ thresholds), 0V-cell charge per IC variant.

Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.

Good for

  • Protecting bare 18650 and LiPo cells
  • DIY battery packs
  • Adding safety to kits
