100 a/h Lithium Battery for $21?
Saw this ad this morning, a 4-pack of 12v 100 a/h lithium batteries for $82.99. So 400 a/h when linked in parallel. Our new-to-us 5er is a 2008 model, so I'm aready planning new electronics, conve...

Thoughts on this battery?
The lifepo4 battery in your link (12v 100ah) is only capable of producing 50a of continuous current. They got the price down cutting-corners with the BMS and the wiring. Even two of these cells paralleled will only provide you with 100a of continuous current. That's not enough to power a microwave or other high current device with a 2000w inverter. Two 100ah lifepo4 batteries, capable of 100a of continuous current, paralleled, would be the minimum I'd use to power a 2000w inverter.
Of course, if your power needs will remain minimal, now and in the future, then this 100ah 50a battery might be worth considering. Me, I'd pass.
