For HPR how much current is needed to ignite the motors. A-K ??
Our club systems - our launches are combined Tripoli/NAR - both use 12V vehicle batteries, a motorcycle sized gel cel for the LPR rack and car/truck sized battery for the HPR pads. I don’t know what AH or CCA rating either has - sorry - but we’ve never had them fail during an all day launch session. My Estes #2240 PSII Controller uses 6 C cell sized batteries and has easily fired up any H motor and below I’ve used, even with cheapo bought on the fly convenience store alkalines.For HPR how much current is needed to ignite the motors.

A-P+ motors are all about the same current needed. As @waltr said, it's the amount of pyrogen that's different. I use a ematch and .50 cal Pyrodex pellet for my EX M motors so that probably needs less current than Estes igniters.For HPR how much current is needed to ignite the motors. A-K ??
