"Oh Look I Am Pasting This On The Front Of My HF Charger

KWH is sure a valuable feature. On a device as powerful as HF, it won't even take a week to see the first kilowatt-hour proudly flowing in :)

The "10A" HF charger has been clocked at 19A in the mid 13 volt range. That's about 250W. Your kWh is registered in that week minus about 6 days, 20 hours. :)

Here's one: 20A DC kWh Meter. Wish they made one in 200A.

That link gives me this message from e-bay:

Seriously though, energy meter of some kind is a useful thing with any charger. Energy measured in watt-hours is practical in residential applications, while kindergarten grade amp-hours is the lingo of choice in RV and automotive world.

my Turnigy watt meter / power meter does all that
Turnigy power meter

The TURNIGY watt meter is a very accurate R/C amp/watt meter.
Predict model airplane flight time with any given propeller.

I do like the larger scale readout on Mex's meter

Why? Well this is a digital ammeter good to fifty amperes. No biggee. OK, add on a halfway accurate voltmeter, something the HF and few other chargers have. BUT WAIT! THERE'S MORE!

This meter has kWh measurement capacity. Not kindergarten grade mere amp hours. It will display the amount of ENERGY that is delivered to the battery under charge. Total accumulated energy.

By using and keeping track of voltage baselines, and determining the amount of ENERGY needed to bring a sealed valve regulated battery back to full OEM at rest voltage, a person stands a chance of knowing the state of being of a valve regulated battery. Yeah this means an AGM battery. Not bad for 25 dollars.

Wow. Never thought I'd see the day. Look up... for the end must be nigh!

If you have to do this manually, Query EBay 12VDC kWh METER. That otta do it.


I have to go north for the battery, like a several day long trip. So at this point the AGM remains a drool. Think I have pretty much settled on the Odyssey.

OK where did you get this meter?

Well... judging by the annotation in the upper left corner... I think I can guess where it was made, at least.

Are you employing AGMs these days, MEX?
