Wow nice to see someone on you tube that really knows their stuff. Did cars for 34 years and specialized in electrical and computer system problems but no experience with RV's till I got my own. On my 4th rv and struggling with battery issues as I dry camp most of the time. Have 4 golf cart batteries and 2000w inverter 500W solar on roof and 300w solar external I can move around when camping in tress.. Worked well for couple years but having issues and want a look into something better. This video really helped and I feel I can trust your info because I can tell you really know what your talking about when so many you tube videos the presenters are not very knowledgeable and often suggest things that are dangerous especially to DIY'ers that don't really know what they are doing or have little experiene building fixxing or designing things. Thanks !!!!!

It's always nice to hear from someone that has obvious expierience... so many on youtube simply read and repeat without understanding.

Hi Ross, good content. I do have one request and that is mistake 3. Even when you pull positive one on end and the negative on the other end you will will have a major imbalance in load. There was a time I believed in item 3, but NO more! Take a clamp meter and you will see this in real time especially with lead acid. I have since changed over to use a buss bar on all multi-battery banks! LiFePO4 works so much better with a buss bar. The key is to make sure all connections are torqued the same to manufacturer specs and then test it with a clamp meter! AGM and lead will still see fairly un-even swings until the batteries are balanced but over time they self balance! I highly recommend clamp meters, because everything is just guessing without one. Cheers. Gary

Ross: You really have enlightened my brain and broaden my vision on things I did not even know, clicking on this post was the best thing I did since last 2 years ,almost every thing I wanted to know about lithium solutions you havegiven the answer for here .... and all in under 30 minutes.. keep up the good work Champ.. God Bless You

Good one. As an installer/designer for 20+ years you are spot on!

I hope that this comment helps you with the algorithm as much as your excellent content helps us. Thank you Ross!

Your fist point is fantastic. So many companies state...well you have LiFePO4 batteries now so you can run anything...checking the maximum constant discharge is key.

Great points. I glad you covered fuses,

I love my Victron gear but their battery and Battle Born seem SO over priced. Thank for the video, great tips

Excellent presentation. Thank you for doing a detailed job.

This confirmed some of the things I had installed, and gave me thought about others I've omitted. I guess I have some wiring to do.! Thanks for the upload.

I have a fairly decent knowledge in this area but still learned from this video. Great job!

EXCELLENT and very understandable and practical technical explanation!

Really interesting and very helpful. Great presentation style. Thank you!

Excellent tutorial and easy to follow and understand. Thanks.

Thank you, many points I need to pay attention to on a project I am working on.

Sigh. You confirmed a concern I had about my new install. 🤔 😊 I put breakers and fuses on everything that charged or discharged the batteries, but only a disconnect switch on the main battery cables, thinking since I had breakers for everything else, it should be fine. But I wasn't totally OK with it, and you pushed me in the right direction. I'm going after one of those fuses that mounts to the battery post, as that looks like the best solution for my system. Great video with clear explanations! Thank you!
