cell harvesting

[_paralyzed_]

A 5s2p 7200mah pack for $75 shipped. And a little assembly. Anybody think it's worthwhile?

I seriously doubt that those would handle the amp draw of rc.

These have very low c ratings - so no...

Those are lithium ion, but.......it doesn't mean they are the high discharge type. I'm also sure there is a pcb inside to protect from over discharge rates and over voltage discharge.

Lithium Polymer cells have such high discharge rates because they have such a large anode and cathode surface area.

The amount of this surface area (and the overall electrilyte chemistry) determines the "C" rating for maximum discharge rate.

Alot of the lower end cells, such as for cell phone use, have "C" ratings around 5C or may even be as low as 2C.

If these are 2C cells, for 5S2P, the maximum Continous Discharge Rate of the Pack will be 14.5 amps.

Hardly good enough for RC, but you could make one heck of a pack for........ummmmm a camping lantern?
