This is more immediately pertinent with regards to laptops, but hopefully, this will trickle down to single cells relatively quickly, but basically some company found a way to use nanoparticles to greatly improve the efficiency of lithium-ion batteries. They're talking 300% more power and charging times of *minutes*

My li-po setup charges in 20-25 minutes, but the power increase rocks!

Yes, poly's do have a higher discharge rate over the ions.
But, they don't have the safety feature.

can you solder lithium batts without solder tabs?
with a radioshack coldheat?
normal soldering iron?
can i some how glue on solder tabs?
Please don't flame me i just bought four cells and I don't want to put them in a aa battery holders!

ColdHeats have been proven to be bad for electronics, so don't use them on any of your R/Cs. With li-pos, they all have tabs, so that question's answered. With li-ions, as long as you're very careful, you can solder straight to the batt, but you must be careful. My advice is to stick with tabs.

woah that was weird you replied in like 5 minutes,hehe
thats what i figured with the coldheat...thanks for the reply
anywayz when you say be careful do you mean? that i shouldn't heat it up too much?
I'm of course going to tin both the wire and the battery...and when i tin the battery before i put the wire on i am going to let it cool down for a minute or so. Is there any onther precautions i should take?
