Hi guys,
I found this cheap li-ion pack on Aliexpress.
I want to use it for a long range terrain robot like this one:
I wanted to go for 24V, but they are very expensive for me. So I think the best route would be to go for 12V batteries.
The robot I'm planning to build shouldn't be very big. A 25cm x 30 cm should be enough.
Might be cheap.
Looks like a classic lead acid gel battery to me, given the size it might be 12V at 3Ah, or could be less.
For $5.82? That should tell you something for sure.
In the product page, there's a picture showing that it contains li-ion cells.
But I'm pretty much sure that they are cheap li-ion cells.
The whole package, battery + charger + cables for $34.
I wouldn't charge it indoors... Remember all of those exploding hover boards a few years ago? 
Yep, you're right.
