Finally pulled the trigger on my first lithium battery for our off-grid cabin! 230Ah 12V for just over $500 including tax when using the $50 and 10%-off coupons in addition to the lightning sale. I almost bought this last week, but held off, and I'm glad I did. I don't think we're likely to see this go much lower any time soon, but I guess you never know. Looks like the sale is going until 11/9 at 1:40am EST, so if you happen to see this and you're in the market, now would be a good time to snag this one. It's one of the few cheaper ones that gets the thumbs-up from Will as well.
Now I just gotta find a good AC charger for it so I can start testing it out. I was thinking about this one: https://www.amazon.com/Battery-Charger-Lead-Acid-Maintainer-Motorcycle/dp/B0B3CV4S2Y
Anyone have experience with it, or any other recommendations?
