Hi Feathermerchant, thanks for the tip. I found some good stuff at Esprit.
I think I should have 2000 to 4000 mah. I don't know the difference between the following but all have 2 to 4k mah and 11.1V.
Kokam k40003s2p $150 11.1V 12.75oz
Thunder Power TP2100-3s 2100mah 3cell $75
Tp4000 4s2p $180 11.8oz
Tp4200 3s2p $145 10oz
Multiplex 4000 Mah 2s3p $140 This one was listed as a good buy.

2s3p, 4s2p whats the difference if I get 4000 mah and 11.1V?

NiCd
2400mah Sanyo scr 12 cells $70 25oz
2400 14 cells $81 29oz

will the 2400 nicads only last half as long of flight as the 4000 lipos?

learning slowly but surely,
Carl
