One other suggestion, I am running two strings with 2 solar controllers. one is series at about 120 volts and the other string in series at about 60 volts. Am using 10 gauge on each string down to controller. Shading on modern panels is not such a big deal anymore. I can have one of the three panels in the string shaded and still get at least 2/3 of the voltage and amps.But with that many panels, you will have to run series parallel or have many controllers and lots of wires.

Been buying panels off him for years. A straight shooter. His house/shop has, I believe, a 20000 watt grid tie system. Believe he installs them for a living.

https://en.wikipedia.org/wiki/Electric_bicycle_laws If you scroll down to US regs, appears that any electric bike with pedals, that has less than 750 watt motor and a top speed of less than 20 mph is classified as a bicycle. My rad mini is governed to 20 mph. I am sure without the governor it would go much faster.

I bought one for my series 60 from these guys, https://www.xtremediesel.com/semi-truck-big-rig-class-8

Appears from their website the Aims are $899, same price as I paid for the Battle Borns. Strange in their description, they state in bold letters," WE DO NOT ACCEPT RETURNS ON THIS PRODUCT" As stated in a previous post, BB will pay for your return shipping and send you a new one, wonder how that would work with Aims if you have a problem. Lion looks the better deal, $799 with a lifetime warranty, which is a little vague. They are 9 lbs lighter than all the other 100 a/h lithium-ions, so would suspect they use some different technologies. Dewillso has mentioned the problems with Renogy in a previous post. Curious to what you think the weasel words are in the BB warranty? From what I have read, BB bends over backward to replace any defective battery. With a BMS would be pretty easy to see if it was a defective battery, or misuse. BB also has hi/lo temp and voltage cutoffs built into the BMS, I left my coach unattended for a week with both vents running and when I came back the BMS had disconnected the batteries, so I know it works. If you find any negative posts on the Battle Born's, would appreciate you linking them .https://battlebornbatteries.com/terms-conditions/

That is a good price, Their website states a 5 year prorated warranty. Battleborn has a 10 year exchange policy and always answer the phone and can even tell you how to set up your charger to charge them correctly. To me it was worth the extra money. If BB has blems or have them on sale, you can get the 100 a/h model for $900 shipped with no tax. [If outside Nevada]

What are the three other companies? Are you sure all the batteries have the same cells and BMS? Battle Born says max voltage should not be over 14.5 volts.

Think you misunderstood. He was talking about buying a used Newell and saying it would be worth close to what he paid for it in 5 years, opposed to buying a new coach for $100000 and it being only worth $50000 in 5 years. The most expensive Foretravel sold in 2001 was about $500000. New ones cost from about $550000 up to 2.5 million.New Newells are $1.9 million and up. But agree 2000 to 2005 Newells and Foretravels are a great bang for the buck. http://beamalarm.com/foretravel-links/models/2001_foretravel_u320_specifications.html

All the big solar panels, [300+ watts] made in the 10 years have bypass diodes. These greatly reduce the effects of shading. Have run panels in parallel and series in the same situation, and find not much difference in output. The bigger panels are a much better deal per watt, but are higher voltage and require a MPPT controller. Many charge controllers today will take 150 volts, and a couple 250 volts. Most home grid-tie systems run up to 600 volts in series, so it is now mainstream.

Have had 6 of them for about a year, Not cheap, but probably the last house batteries I will ever buy and many advantages over Lead acid. Many inverters and converters can be programmed to charge them. Call Battle Born and they can tell you if you can use the charger you have. Biggest advantage is you can charge at 1C in bulk, till battery reaches 100% SOC, and of course can use the full capacity, so my six 100 amp/hr batteries at 180 lbs total, will more than equal the usable output of four 8d agm batteries at 640 lbs total, and take up less than half the space and charge 4 times faster. Only drawback is the second mortgage I had to take out to buy them

If you run your panels series/parallel, should be about 80 volts nominal, so about 15 amps to the controller, so #10 wire is okay, if designed for that voltage. Have to make sure your charge controller will handle that voltage also.

For me the very best feature of lithium ion, is the ability to charge at up to 1C to 100% SOC with no absorption stage. So if I have used 200 amp hours out of my battery bank, and I can get 80 amps from my panels, and 120 amps out of my inverter/charger, in 1 hour, I am fully charged. With my old agm batteries, that would have taken 6 or more hours. Of course, unlike Lead Acid batteries, lithium batteries never have to be charged to 100%.

Thinking he made a typo.More likely outtahere has something like these. https://www.solar-electric.com/rec-n-peak-series-320-watt-monocrystalline-solar-panel.html?gclid=Cj0KCQiA5NPjBRDDARIsA

94 volts out of of three 120 watt panels?
