[chuckstewart]

Most people think solar is a few panels and batteries watching your videos, I have come to understand how important it is to properly engineer your system and use proper components.

[theghostoffrankgrimes]

The grin on your face every time you talk about overload testing is so genuine! 😊

[sherpa]

Hey Will, you will need a shock and vibration test set-up for doing marine applications, especially for small vessel applications. More toys to play with😃

[Alphastarcar]

Your channel inspires me to keep building my home solar system. Thanks!

[samhklm]

"Nothing smells bad - thats a good sign" Will - you are stealing my secrets dude!

[forrestallison]

I would have no qualms starting my diesel sailboat boat motor. I'd really love to see you testing starting engines with this. I think that's really one of the largest applications where everyone is still using lead acid and so I'd guess that's a lot of what they're targeting.

[MrAce]

Love the work you do on your videos. When you’re running batteries in a series like that you do charge them individually they make 3 or 4 or 5 bank chargers, just for that

[johnsexton]

Timely review for me. I am about to replace the house batteries for my camper. The change from Lead Acid to Lifepo4 has been in the books for quite a while, actually long overdue. I was doing a comparison of what is available here near me, saw the LiTime battery and thought, I should check to see if you had reviewed them, and voila! Thanks for the very useful reviews

[cottsak]

Mad respect for removing the previous video. It was the right call. 💪

[RicoCantrell]

That's awesome!! Just slightly more expensive than a lead acid deep cycle. Perfect for a mobile home.

[ronmoore]

Whenever you are doing High amperage tests a thermal imaging camera is very informative. You can see which connections are heating up.

[FHSU]

Thank you so much for all the reviews and knowledge you pass along to all of us!! The question I have for you is, where did you get your work-benches?

[Diyfix]

These would be good for a washer and dryer in an off grid Environment is what I surmise where I could utilize the higher current, any more ideas? I guess a bigger oven or toaster as well… I got a bunch of the new Bluetooth ones and they are great. I did complain about the sign in feature, though, as you have in another video, but they seem reluctant to change it

LiTime Bluetooth 12.8V 100Ah TM battery currently on sale for $229 on their website. Not bad for what you're getting!

[maritimetees]

These are getting pushed for boaters. ABYC has recommended Bluetooth on Lipo, So many boaters switching to lithium now in their house banks. I am one of them. Our systems in the US mainly run on 12v. I have 3 12v litime in parallel for my house bank. Reason space! These have worked flawlessly. I actually went with your recommendation. Why buy battle born? For 3 it was less than 1 battleborn. I wanted the 12v 420ah but could not fit on my sailboat.

[adamdevereaux]

The BMS is likely cutting off due to temp of the MOSFETS and will try to turn back on based on temps dropping. Notice that when you let it cool before the 500amp test it actually ran longer then the previous ~300amp test that was back to back.

Makes sense- make the BMS cutoff based on the actual potential issue: overheating. Instead of being based on a fixed time interval.

[Cjaiceman]

I love that budget oriented batteries are starting to become harder to tell apart from their more expensive counterparts for features and value.

[lonestar]

Hello Sir, been watching u for about 3 years now. U the only one I really trust with Lithium. Tryna add some to my car and have no worries of burning it down. Anyway we can get into contact (I'll pay for ur time and knowledge). Thanks!!!
