Should my batteries and solar have a load ?

They’d run rings around young guys , it’s a myth young people know anymore about this stuff , some do, many are clueless. Contrary to popular opinion kids arnt better at “ programming your video “. When the IT systems fail, my kids just hand the stuff to me. !


Im involved in microprocessors since the damm things were invented. Yiu want a doctor that’s operated on 1000 patients , or some young guy that read a book and has done 1

That's the point.

You and your college buddies would be embarrassed by the young guys because the young guys were doing what you folks learned in college possibly in middle school.

You are isolated from the younger techs / programmers and don't realize this.

I don't think you were sneaking text messages to your girlfriend in HS or setting up computers, cell phones and playing computer games online in middle school and programming

I know what you know since I live in the same era.

You and I had to drive to the freaking "computer lab" to complete our Pascal, Basic, Cobol, or Fortran programs!!!? Then print them out on a line printer.

(my degree is a BA in History, but I took a lot of crappy classes which were a waste of time like math, geometry, calculus, and computer classes also)

These kids of today don't understand such things like driving to have access to a computer.

I mentioned the 80 mega byte drives we used to have which were the size of the fridge we have in the tech room and they were like 80 GB?

I was like no 80 MB!

Their knowledge is vastly superior to you and yours from back in the early history of computers and programming but it isn't your fault you were simply born at the wrong time

Plus you need more than coding these days, you need to know and have a cert in the all the OS's your systems are running plus other certs in Cyber and Computer Technology

Hell they even made me qualify as a computer tech and I have been a manager since 1995! I'm an electronics tech. (or was)

Hardware Techs need A+ at a minimum (two 90 minute exams/1000 page manual to learn) just to keep their job (me included), Cyber Techs need Sec + minimum if you want to check your knowledge see link below.. Network + is also good for the hardware guys to have.

PS. Certs have to be updated every three years and you must pass the exams. (or complete continuous learning objectives in the mean time)

That is *almost exactly* what goes on with folks mistaking amps for amp hours. Best of luck.

Took the SAR boat out yesterday and we had to go about 10 knots out. With the conditions, we kept it down to about 15 knots per hour

You must have missed it.

That may help you.

What that means is that if you discharge over 20 hours (i.e. at 5A), you will get the full 100Ah if you flatten a fully charged battery. Discharge at a lower rate and you will get more Ah, discharge at a faster rate and you will get less Ah before flatteing the battery….

I have been using Lead Calcium for about 25 years, they are the perfect companions for my Victron lithium batteries.

Century, ACDelco dodgy?

One more plug for a Victron MPPT Controller.

Yesterday was the first full day with the Victron Controller hooked up.

The Victron will tell you the history of your batteries charge cycles so if you are away from the boat for a week you can see how things went as far as your batteries when you return.

So I thought the thing would never go to Float yesterday

It took over 7 hours in Absorption Phase which tells me maybe my batteries were never charged fully with my PWM's....

I'm still researching proper settings for Float, Absorption, and Equalization. These settings are the ones I found yesterday for batteries similar to mine

So do yourself and everyone else a favor and learn the proper use of the terms if in the future you wish to ask for help on the subject.

Might have been a smart guy just testing.

You don't teach an old monkey how to make funny faces.

Can you help me tune the carbs on my Tesla?

[thomm225]

So if you did go with a Victron MPPT Solar Controller like a 75/15 there are a few differences between the one with Bluetooth and the one without.

The unit without costs $88.40 on Amazon, and the unit with Bluetooth costs $118.15

To monitor the none Bluetooth Unit on your Laptop you'll need the Victron Connect Cable. (which I still have from my old Victron)

Also the lighting scheme on the units is different and that threw me off a bit as I was expecting a blinking light for Bulk Charge Phase not a solid Blue Light when I first hooked it up.

Both types are great especially if your Laptop is close enough to connect without taking it out into the Sun.

I bought a USB extension before but also have Bluetooth now so it's either or

Odd... most Teslas have been put on a low-carb diet at the factory!

Yet another comprehension problem

That's twice you have been asked, and twice you've not provided the data sheet for that battery. Directly from your reference, here's the actual datasheet column heading. No sign of a 90Ah battery in it.


And no sign of your "12,8V/90Ah, PN: BAT512090410 (last sale expected 2019 Q1)" in that document.


I presume that is just text on a webpage containing your link. Which is NOT what was asked for.

Looks like the kids are still playing but ......

Here's another great idea for the OP as to how to remotely monitor your batteries charge. (using a Raspberry Pi)

Second video shows how he powers his Raspberry Pi directly off his 12 volt battery(s)

Sure, do you have the correct frequency tuning fork? (I'll bring my own metronome).

Jim

Oh darn that’s why I can’t do that
Thanks

[thomm225]

This is probably the best idea yet for the OP since his boat is in a remote location.

First purchase and install a Victron 75/15 (Bluetooth) MPPT Controller.

Then for fun get a Raspberry Pi 4 and setup your remote viewing system. (per the video)
