I saw this in ebay and wondered what you experts think of it. I'm thinking of buying it.

I have a lot of lead acid batteries (probably 25 - 30) for various things like battery backups, motorcycles, cars, solar arrays etc and this device looks really good for periodically checking the actual capacity of the battery.

Maybe you can see something that doesn't look right?
Can I have your opinion before I purchase? Thanks!

DC 120V 100A Wireless DC Voltmeter Ammeter Power Meter Capacity Coulomb Counter



  • Features:



    1, wireless data transmission, eliminating the trouble of wiring, but also to avoid errors caused by line losses.
    2, bidirectional current detector for detecting the charging and discharging of the user can easily detect bidirectional current without changing the wiring.
    3, power and memory function, power failure after the settings can be saved before the power failure memory and when An, watts and time, to facilitate the observation and measurement.
    4, voltage, current, power, discharge capacity, and the time when the tile display simultaneously displays information fully clear.
    5, with overcurrent, overvoltage, undervoltage, limit protection (extended relay time) and other functions.
    6, when the number of security, and the time when the wattage clear function, does not affect the measurement.
    7, can be set up to address each individually, and with a view to display a plurality of measurement parameters measuring board.
    8, the use of multiple machines simultaneously, the machine can be set individually for each channel to avoid mutual interference.
    9, with a screen lock, time off, brightness adjustment and change the language display function.

Sounds pretty cool. But it mentions wireless data transfer without specifying what that means. Make sure it meets you needs. What does this thing cost?

It's around $25.00.

I was reading all the feedback and there were a few that mentioned problems so I'm not going to buy this until someone chimes in to say they've had one a while and it works well.
