Wireless 100 amp monitor with bells and whistles

Times have changed. Few years ago an averagely cra.appy V/A/AH meter was selling for $25, accurate models for $50, but they were all wired. Wireless is a big thing when it comes to amps.

Somehow I doubt that this is something accurate - throughout the entire range, or durable. In less than a year the seller and manufacturer will probably be long gone.
