The only controller I’ve used since becoming a BAR for cluster - and two rocket simultaneous - launches has been my PSII controller. I’ve used alkaline throw away C batteries and NiMH rechargeables - both worked fine. I used alkalines for at least two school aged build and fly workshops where we did multiple two rocket simultaneous launches. Granted, those were 1/2A Estes BP motors in Art Applewhite paper rockets on the alkaline batteries - I had the NiMH rechargeables for the last one I did with ModelRocket.us Turbos on A8 Estes BP motors. |
