a comparision of two different LI chemistries

Was thinking Li-** was a consideration.....WAS.... :P Seems way above my pay grade. So I'll wait til an idiot proof set up becomes available. But for schits and giggles, I'll add that DIY link to my Sunday morning gawk list. Thanks!

If you have time to kill start here for the diy.

I'm going to guess build your own. There are some pretty good deals if you don't mind the wait from china, 30-45 days. Of course you'll have to figure what bms to get, but it's not rocket science just a little homework.

Steve,

Do you have a link to the 280 amp hour LI at that price?

that soesnt seam like that good of a deal, you can do a Lipo4, 12v 280AH for 320 plus shippingwhich is stupid but if you get a few people in on it, it becomes not bad and that gives you 3000 cycles at 90%

I will do some more reading on them though.

I think that is pretty darn impressive.

Those look interesting and up here in Canada so no cross board tax/shipping nonsense. Pretty steep initial investment but if it's cheaper over time, it be a win.
I'll look into if they need a special charger. Could make Li-ion or these prohibitive if you have to completely replace your system.

all advertizing and bending studys to suport your purpose. they never mention what batteries they are testing so there is no base of comparison. coule be a top of the line against the most cheeply made LFP battery.

IMHO a valid markerpoint. A 2M 10-year point on average would go a long way in my book but for me the time issue is irrelevant. 5-years for me means eternity.
