Check this out, a new LiFePO4 cell giga plnt in the US:

I agree ! Excellent presentation of proper technique.

Don't drill too deep into the battery aluminum term point. I hope you can extract the broken stud from the aluminum term point before you start the heli coil install hole drilling process.

Charging below freezing temp is not recommended for LiFePO4 batteries. But here is an interesting discussion on the topic.

Here's the best explination of mobile electrical system groundingI have found. https://diysolarforum.com/resources/grounding-made-simpler-part-4-mobile-systems.159/

In my opinion Grounding is so hard because there are terms and concepts used when discussing grounding that are very basic and universal in any regulation compliant area that are no understood by the general public. Basically do it your self solar community needs to make the effort to understand...

What's the latest on Magnum inverter tech help and warranty ?

I would like to note that this is the one and only post identifying this problem with BattleBorn batteries. I bought mine years ago and have not had any problems with them. I suspect this is not a common problem or recurring problem.

Use Silicon Bronze fasteners. There are a few that have an astm certified rating for strength that cn be torqued higher than non certified ones.

Can you give more info about your metal cased batteries ?

They double nutted it, better than thread locker.

Why is it important to 'reset the BMS ocassionally' ?

Took me some time to find this pic of my battery package devices and wire. In 2019 when I built this really compact 3P 12v BB battery package (to fit in a really small tight space, the generator compartment of my old Lance Y2k camper) this is how I stacked the wire lugs on the the battery...

BB Terminal 3 pic seems to identify the problem best in my opinion

I have just read this entire thread end do end. I cannot find any explination of the peoblem or short coming of the BB batteries mentioned. I'd really like to know what the problem was. Can anyonee enlighten me please ? Sorry, I had not read the entire thread, my mistake. I found the...

You might want to start by thinking about voltages. One 120v line from the solar panel inverter is a two wire system, Hot (L1) and Neutral (N) wires). 120v ac from wire to wire. If you were running your minisplit on 240v ac before making the solar/inverter circuit change, the panel had a three...

Keep in mind that if you value your investment in your RV, you might want to insure it. Try insuring an RV without the RVIA cert sticker on it. . RVIA-LV ANSI standard Chapter 9 Refrence Publications pargraph 90-1 "The following Documents or specific portions thereof are referenced within...

How false this statemment is ! NFPA NEC Article 551 RV's and RV Parks apply. This article Information Note Low voltage systems, refers to NFPA 1192 standards for RV and ANSI/RVIA LV, standards for low voltage sytems in conversions ane RV's applies also.

Have you ever encountered 'compact stranded' copper cable ? The strands appear to be somewhat rectangular, they are not round. They fit together snugly leaving very little air gap in viods between them.

Would they consist of alpha, beta or gama rays ?

Why is paypal so good. I know why credit cards in the US are a good way to pay, but why paypal ?

Ugly American !

"it does give a link to the US Gov website re: grounding requirements." I looked for that link, but missed it. Could you direct me to it ?

System grounding has been covered many times and in many ways on this bulletin board. There are well researched and presented resources here under the resources subject matter. It's best to start there and refer others to those resources in my opinion. . PS: One ground rod is not accepted as a...

Making grounding simpler to understand is a tough goal. There are concepts to grasp that include termnology, safety, and purpose. Giving others advice about grounding based on your system setup is just fine, but may not be relevant or correct if you do not understand electrical systems...

Learn first. Buy second.

I don'thave any suggestions but have observed that professional power supplies can cost thusaands of dollars. Here's one very good example: https://www.valuetronics.com/product/62150h-600s-chroma-dc-power-supply-used and another...

Good luck with that. You are dealing with a Chinese manufactured Product sold by a Chinese company. Think about it. If you bought it using a Credit Card from the US, the CC company has to refund the money after they perform due dillagence on your claim.

WHen you discuss LiFePO4 (12v) battery charging with an automotive (12v) alternator, you need to include wire connection specs. If you use 4/0 copper wire, alternator to battery, the charging current will be much higher than if you use the 12 gauge wire usually found in the auto wiring...

I thought it would be easy to find some nearly square solar panels. Having trouble finding many. I have space for to panels, One max size 42" x 30" One 42" x 36" Anyone had success with any particular brand model of Solar Panels that are Dimensionally Square ? [Solar Panels will...

That must be if your facility is in Canada. What if it's in the US ?
