I have 650 amp-hours of LiFePO4 batteries in a 12 volt bus on my sailboat. The batteries have been in storage for four years, and my...

how long of storage are you talking? Biggest concern would be a micro draw from say a SCC or BMS. There is an article on an LFP bank in...

I call it charge momentum. I imagine it would be hard(pricy) to design your typical SCC to be fast and efficient while also avoiding...

3 x EG4 Chargeverters, max. 300A total/100A each. One on each phase. No issue, I do this with 2 atm. here.

Hmmm, thats the charge controller I want to use. I am wanting to use 300w panels in a 2P 2S. Panel VOC is 39volts and ISC is 9.8amps. I...

A cheaper option is you could hook up about 20 used hoover board wheel motors. 2S 10P should work good..... I'm joking but....maybe.

I currently have 7 arrays on one system and 5 on another system. Each string of panels is on their own charge controllers(all Victron)...

No need to switch them off and on. Likely you will get solar from both arrays at the same time even though they are facing away from...

Nothing would surprise me anymore.

That is the first thing you need to find out. Once you are connected, there are laws preventing you from disconnecting.

That will be an interesting contract

One thing mechanics do is to keep a broom stick near by when working on hybrids or an EV. That way, if you get shocked, someone can...

Just wait for the EG4 pull behind trailer to come out of beta testing....I think they are just a couple of firmware updates away from...

Will never happen. There will be an epic eventual failure followed by an epic lawsuit.

I was able to catch the video minutes after it posted. It was surprising and very concerning. I think they should repost it, could be a...

Or about $22,000 for some cells for DIY packs(not including BMS and other misc).

You can find various discussions about that video on the web but the video was scrubbed. This was a discussion in this forum. And here...

Did anyone catch that video before it was taken down that "Projects in Paradise" youtube channel posted about the 12v battle borns in...

Lol....probably a quicker charge then waiting in line for 10 hrs....

I saw a video today of a solar weed wacker. Dude had a panel strapped to his back, landscape orientation. No battery in the set up at...
