5 year warranty tells a lot! But obviously they will not cover you if you let the battery to drop bellow 9V or you've a faulty charging system.

I know they sure are light weight. When you pick one up it just feels like an empty plastic case!
The OEM Yuasa is over a hundred bucks so the lithium price isn't terribly out of line if they last longer. Still, I get maybe 8 years out of lead acid batteries so that would be hard to beat.
Are there any with bms that have the current to juice a starter?
No, there is no such problem with starter LFP batteries, like EarthX, etc.
The only problem is that the BMS itself increases the self discharge of the battery.
9 months!!! it can be defective...
NC's alternator can provide 420 W at 3,000 - 5,000 rpm. It should be enough according to other owners. Sorry, I can't tell you for sure without some real world testing. There's no time and money for that
Try to keep the consumption to a minimal. But you can to turn everything off just about 10' before your destination to charge a LFP up to 80%!
I never liked gauges like this, they're not accurate. Every battery has different readings. (e.g. Yuasa, Varta gives 13.0V when fully charged w/sulfation stop, other Pb 12.8V, LFP 13.6 V). Just install a voltmeter like Kosso mini3 to monitor the charging system, and a plain voltmeter to check your battery. (It would be a nice idea if you keep a log for some time).
More about battery readings at a later time.
Well glad yours is not broken but mine does not take a trickle charge well. It took all night for the trickle charger (tender JR.) to take from 12.49 to 14.50 and keep the green light on.
A Battery Tender Jr. will charge at a maximum of only 0.750 amps. If you have a "good" 11 AH battery that is 1/2 discharged you will need to put over 5.5 amps back into it, which will take over 7.3 hours to charge back to full capacity. A "weak" or "bad" battery under the same conditions will charge very quickly as it will have a lower usable AH capacity. Taking a longer time to charge on a charger is usually a good thing, unless the battery has a shorted cell or other somewhat rare issues.

Because high current produces lots of gases. In that case they will be released from the valve of a VRLA battery, and it's impossible to replenish the lost water. In a traditional wet battery this is not a problem!Sealed batteries have always taken longer to charge than the good old screw open the top batteries. Don't ask me why, because I can not explain it, I just know they do. I have a multi unit Christie charger that Honda requires the dealership to use, and sealed batteries take longer even on the Christie charger.
