i was wondering why my lithium-ion batt. has round cells, and what is the differance between lipos and lithium-ions? or is there? is this just another way to spell it? i also saw it spelt li-ion, are these the same battery? if the same than why does my battery have round cells and a lipo has flat cells? do i have to charge differant? details please, the pic below i got from towers web site and is listed as a lithium-ion i also use it in my heli. thanks

Short version: Li-On hit the market first. Metal encased cells.
LiPo is built in a semi flexable sack in layers instead of being rolled up. Seems LiPo technology has progressed better to meet hobby needs.

Is what you're calling li-ion the same as what's called 'lilo'??

If they are, then no, they are not the same since they charge to different cell max voltages. If they are not the same, then I don't have an answer to your question.

Checking Wiki on li-ion - it gets confusing -

Seems the 1st one listed under positive terminal in the table is what we've been calling lipo. the 4th one id a Life, but beyond that, I don't know which or what a li-ion is.

My iCharger has setup for lipo, lilo and life.....those all charge to different max cell voltages. I've seen this asked before, but haven't seen it really answered.
