But you folks out west and southwest, this is a time of great opportunity for you. I'd need grid power from about mid December until mid March or early April here. Therefore with 18 packs not more than 5 packs should be replaced. RECOMMENDATION: Not more than 25 of the battery packs of a battery set should be replaced. I dispute that having lived in this area for 68 years. When using unapproved spare parts, all guarantee, service, damage and liability claims are forfeited. Their map said my area has 76% saturation. It's a little pricey at 1 per cell but otherwise seems ideal for my needs. I don't have that 20 years to wait for the break even point. I saw something called Battery Blocs () that seemed to be a good system for easily building and rebuilding battery packs without having to solder or spot weld. This late in life, it would not be a wise choice for me. On average, I pay about $800 a year for electricity. Well, over 20 years, that comes out to $900 a year. One of those links leads with "Savings of $18,000", and the fine print says "over 20 years". When you take in $5000 for $12,000 of used clothing, tell me how that is making money? Same basic concept. It's a bunch of snooty women with expensive clothes they no longer wear and they make claims like "I paid my my new car with the money I made selling on Poshmark." Nowhere do they mention that at some point, honey, you paid $700 for those ugly ass whore shoes you just sold for $300.
Much like the TV commercial for that app called "Poshmark". I just LOVE these adds that wave "savings" around in front of people to catch their eye.
