Looking for a recommendation on a LiPo battery to use for my Estes series II launcher. Need a little more kick than 6 C batteries at this time. Thanks!!
I have an old ElectriFly 1250 3s pack in my primary PSII controller. I had to make an adapter to go from the connector on the pack to the PSII controller's JST connection. There is a similar thread about this here somewhere, in which I posted a picture of this.
I would recommend 3s....and since boatgeek is getting good results with "just" a 180 mAh pack basically anything that will fit should work just fine. I have even fired the infamous Aerotech Copperhead igniters with my setup.
Ah - found the picture....

Well....that depends a great deal on the plane, the power system, and how heavy-handed you are on the throttle. A 750 mAh pack in my Mountain Models EZ Scout would be good for probably three times that. I could easily fly my MM Dandy for nearly an hour on a battery like that. But that's another discussion.
In the launcher situation remember that you're only providing power at ~40mA for the LED and the beeper and then for ~2A for a second or two to fire the igniter for each launch.
With respect to what I use to charge that old 3s 1250mAh pack in the picture above.....I've been flying electric airplanes since the early 1980s and have LOTS of chargers. My favorite for up to 4S and about 4000 mAh is the FMA Direct Cellpro 4s family of chargers. Though these chargers have been around since the early days of balance charging LiPolys (early 2000s) one member of the family is still available: https://www.usastore.revolectrix.com/Products_2/Cellpro-Multi4_3/Cellpro-Multi4_1183
