in some manner yes in some not
LI-IO i think are lighter and less AMP - this why it use for small EP models
the LI-PO are heavier but more PWR and can stand more AMP at a single moment( the top AMP that the PWR source can give ya)
to be more sure and safe!!!!! put a Q in the EP forum
cheers
mate.
You are backwards.
Li-ION ar more stout and take a good beating but are very limited in the amp's it can deliver at one time.
Li-Poly can deliver much higher amp's for longer periods of time and are much lighter. They are not near as strong so installing them into a single cyliunder gas plane can and has destroyed them to the point them burst open. That is rare but I have seen it happen.
Li-ION battery cells are usually round. Li-POLY cells are usually flat
So you want Li-ION for glow/gas planes. You want Li-Poly for electrics
You can easily see this difference by going to
http://www.fromeco.org Take a look at the peerless batteries. Those are Li-Poly and are flat. Fromecos packs those differently than say Thunderpower so they can take the vibrations of larger planes. Also, Take a look at the Li-ION's and you'll see each cell is round
