Thinking about using these to build my first battery. What do you think?
The post says you can connect them together in serial, would they need another BMS other than the one included?

What's that work out to, 13 cents a watthour? Seems to me anything under 30 and you're doing pretty well.

What are you going to do with 1000 18650 cells though?

Buy with paypal for guarantee. Interesting for low watt motor to last.
What you need the battery for motor controller ? There are 36v. So 36v or 72v ez.

They're OK batteries. Nothing high power but with enough in parallel they're fine.

Are you buying 1k cells for a pack? I guess you have some powerwall projects in mind.
