Years ago when Ford still built trucks in Kansas City a friend priced a truck in Des Moines Iowa which is about 3hrs north of KC. He then priced to the same truck here at home. We are 3 hrs east of Des Moines. From KC to here you go through Des Moines. Well the shipping from the KC plant was less here and we are twice the distance.
Go ahead and put two more in your cart and see what the price does.They're back to $149. I couldn't take it! I had to buy 'em.
I really don't need the ones I just bought!
You do not have to buy them but it should allow you to see price fluctuations.
That sounds like something Nash-Finch would do.

One thing to note about Lithium Ion batteries (or really any batteries, but I'll speak specifically about LithIon): The cells inside the batteries don't like having to put out maximum amps all the time. With a 3.0HO, you have 5 cells having to put out all the amps. With a 6.0/8.0, you have 10. With a 12.0 you have 15. More distribution of workload between more cells gives those batteries a longer overall lifespan. Essentially: you get more actual energy out of them because they last longer.
I do if they drop below the $149 mark.
Kinda. Sort of, if you have any real idea of what individual cell capacity is, what the manufacturer set low voltage cut off at and have any control (which you don't) over max charge voltage. Only charging to 75% is absurd, not running too high a charging rate as to keep the batteries cool is more important then trying to hit some % of charge rate to try and get extra battery life. Kinda like driving your car around with 3/4 tank of gas and never going below 1/4 tank. Doesn't work like that. 10% of capacity left is fine. But with most chargers you have no control over any of this. The lights on the batteries are more or less idiot lights that give you a general idea of the batteries state of charge.

I think the last bit of charging on the run of the mill chargers heats them up from not dropping the amperage down, or the unbalanced cells and higher resistance cells heating up. We don't see this issue with rc batteries, balanced cells with a proper Charge curve Don't heat up like these stick packs do. I suspect if I rigged something up to my i-charger and logged the data with one of my tool batteries vs (not that I have the capability)factory chargers you would see a large swing in amperage at the tail end of the charge cycle temps lowering vs the higher temp and constant current of the factory charger.
My biggest issue with the battery universe data is its severely outdated and a very small sample size of one type of lithium cell. I've been playing with these in high drain land and air based rc, high powered lights, ups ect since lithium started becoming "affordable." Outside of commercial/industrial there's no real reason to be trying to double the charge cycles at the expense of work getting done. High voltage is 4.2 volts per cell, which is also the industry standard, finding a charger that's below that is hobby or industrial grade and typically programmable. Low voltage cut off is much more important. 2.4 volts lis the latest standard, but for years 3.0 volts was what we went with. The only thing I agree with is 3.0 volts per cell is about the end of the line for high amperage applications, going below that dips under the 10% threshold and dramatically increases battery internal temperature. There are even some guys that won't go below 3.2vpc as a safty measure. This leave over 40% unused battery capacity (Typically, but will depend on many factors) thats too much to leave on the table. Again I equate this to driving your car and never going below half tank.
It's much easier to do that with standby power. Having a generator or shore power for back up easily keeps them in a happy place. We skipped over the solar battery back up as it's not even close to economical and life Cycles are expected to end around the 10 year mark. (There was a cycle count we were quoted, can't remember what it was for the genrac vs Tesla) were out of power a lot, and extended outages are normal, not frequent, but enough we've been on generator power for a week already. One to 3 days is normal. Hate being the dead end of the line. Even 8 hours of back up was more then the cost of the solar array. Just not worth it for us. Generator is easier till battery tech catches up.
