Installing a Watt Meter on my charging system
I have 2 battery chargers running off 1 1800 Watt Power Supply.

I wanted a Watt meter so I would know exactly how much the system was demanding. It still amazes me how the meter will show this much information when most of the wiring/signals are taken off the Negative side.

It works! Now it's time to figure out how I am going to permanently mount the meter and clean up the wiring! Doesn't sound like much, so I will let the pictures do the talking.

Dennis

YES, I have a case I am working on. Infact I have two, just trying to decide which one will be the best.

Dennis

PS: I am trying to see what the "wh" watt hours results are all about on the meter.

Consider using a kill-a-watt meter on the ac iutlet feeding your setup as well. This works on a wall outlet and generator outlet. I found the information helpful in protecting my generator from overcurrent damage as well as overheating in wall home witing.Enjoy things that money can buy IF you don't lose the things money can't buy.

Building a nice custom case is not as hard as you think. A little imagination, some acrylic, and some IPS Weld-On #4 and you can custom make almost anything in acrylic. Used a Seahorse 920 case to build this setup. One of my main goals building this was no holes cut in the case.

Wow... Very dangerous situation down there...

Be careful to accidentally connect the two cables red and black, together... Charger may burn out...

A friend of mine, accidentally connected the two wires with a screw driver... That hyperion charger burned out.

A case could be a solution.
Handling that case on your working table is not always feasible... Occupies lot of space...

My solution was two chargers... One expensive charger near my working table, fixed on a safe place, and one portable and cheaper charger to go to the field.

I actually bought a "DeWalt" tool box, one that rolls around with a handle. I am putting my charging system in the top storage area. Plus I have room for many field supplies.

Just takes time.

PS: I had my chargers MAX'd out this evening charging 7 batteries. That's why I wanted the Watt meter. It was showing 1500 +/- Watts, 24.0 Volts, and I forget the rest, LOL.

My chargers did it with ease. I love the Icharger Duo.

Well, base on the recollected data, you probably need to get another ac outlet dedicated with a rele dispositive.

That circuit breaker and rele is very useful to protect your stuff.

I have a dedicated outlet for just my setup. Your right, if any more I will need another source and protection.

Nice to see the same information that is displayed on the charger is not that far off from the Watt meter.

I wonder if you can calibrate the charger to the Watt meter settings?

Yes, you probably can calibrate it, but it's pretty close.

Take into account I have another charger powered by the same power supply. When using both chargers (and both banks on the Duo), it's pretty close.

I believe I was charging 6 22.2v batteries when I took this picture.

That's the reason I wanted the meter, having two chargers powered by the same supply, I need to know this information provided by the meter.

It's still amazing to me this information derives from the ground cable from the power pack. It's just a lot of information coming from the ground side.

JMO, Dennis

Kevin, It came as a kit from Amazon, below is the link. I wish they were still on sale, but it's still listed at a good price.

Kevin, not that I am proud of this picture, I have since clean up my work area, I was in the middle of building a few charging leads, but here is my setup. The 1800 power supply is under the Duo, and I have another charger to the left of the Duo in the picture. Compact, works great, and now it's in a roll around DeWalt tool box nice and neat!

I probably didn't need a 100 amp shunt, but I am well covered with this setup.

You have to prove concept before proceeding with installation. At least, that is my excuse.

Give Dennis a break, he has shown a pretty good level of safety with a capped water bottle and for all we know it could be empty.

I know it's not funny, but I keep the water for my soldering station sponge. I guess I picked a bad place to store it temporarily.

I believe I put it there so I would not get near my computer with it!

I was definitely into making leads that day. I can't believe all the items I had on the table getting the job done! I was also making leads for LED lighting, and extending a few balance cables, most of which are not in the picture.

Dennis

PS: I thought someone would say something about all the LiPo's I have laying on the table. I had to test my leads out!

At least you can see my Dean's plug caps in the middle of the mess!

That's the biggest issue I deal with. Infact, I am getting away from them just because of the charging leads. I am always forgetting to put the caps back on, so I decided to get rid of them.

I meant nothing about the water bottle and did not mean any harm. It was just a funny moment.
