Today’s mail brought a package from Hong Kong.
Inside, was a ZKE EBC-A05.
This is a electronic load and charger for battery testing.
It can charge at up to 3A using a variety of charging voltages and profiles. For discharge testing, it can draw up to 5A @12v. There is a TTL-serial interface with a USB adapter and accompanying software for logging and controlling battery tests.
Update: I ‘ve posted a preliminary review, and I’ll be updating it as I go in the coming weeks.
