Got the tires. Date codes were all 3621. Goodyear is or was making Endurance ST tires somewhere at least through September. The distributor that my tires came from didn't have any a month ago, so...

I think you are a candidate for a "suitcase" solar system (ready made or home brew). One you only set out if the Li battery gets really low and you aren't ready to head home.

Another good one. I do not have a converter. I took it out several years ago when it was clear we would probably never be on shore power again. I converted it to a bench power supply for my Li...

Looks like a very effective system.

Steve, Li batteries can be stored below 32F. Check BBs specs on this relative to your Ohio nights (I assume the garage is not heated). So it's usually only...

Very astute question. It should come up more often than it does. The converter is typically a two or three stage charger that ends up in float mode. Float mode holds the battery at 100% SOC by...

Interesting thought. If it's cold enough I would think the heater could fully discharge the battery during a few months of storage. Maybe there is a heater switch on the battery? Let us know what...

It probably depends on the slide mechanism and size. I'd guess the ability to handle off-level varies. So opening it unlevel is a bit of a crap shoot. The problem I see is that if damage occurs,...

I didn't like the idea of a storage tube hanging down so went with this box. It came without a foam seal so I added one. I think it can be had with a pre-installed foam seal. I have plenty of room...

As noted by others, and the link provided above, your converter is not ideal. Normally I would suggest giving it a try. But, in this case, that's probably a waste of time. Here are the issues:

Since it's important to keep the battery fully charged, especially where it's cold, it's tempting to leave the solar panels/controller connected to the battery. With zero load on the battery the...

Jim,

Your 10 amp charger will surely handle about 150 Watts of panel. It might handle as much as 200W but we need to see the specs to be sure. If it will handle 200W, it will simply limit panel...

Mike covered this fairly well. I would add that a charger that gets only to 14.4V will charge to about 99.4%. One that goes to 14.6V will get closer to 100%. So this is splitting hairs. I prefer...

Yes. The BMV-712 is a great choice. It may come set for Lead-Acid and so need to have a hand full of parameters changed to work well with lithium. This is a bit like the solar chargers that come...
