Batteries link package is the crucial item if your project request 2 more batteries. It provide maximum safety protection by using circuit breakers on individual batteries. Common power tools battery with 1 set cells inside(normally marked as 2-3ah) can give 15-20 amp continuous power; with 2 or more set cells inside(normally marked as 4ah and up) can do 30-40 amp continuous current. So depending on the battery you use, I’ll put right rated circuit breakers to protect your batteries.
Custom fit common battery on market from 36v-82v, like EGO, DeWalt, Greenworks, Kobalt, Snapper…
E_PPG power delivery formula base on 80v battery(currently Kobalt already offer 6ah batteries which is the same size of 4ah battery but 50% power)
paramotor 30lb + 4 of 30A circuit breakers with 4 0f (2-3ah)batteries 14lb = 44lb about 10 minutes flight time. can upgrade to 4 of (4-6ah)batteries 22lb
paramotor 30lb + 3 of 45A circuit breakers with 3 of (4-6ah)batteries 16.5lb = 46.5lb about 10 minutes flight time. this setup will NOT work with 2-3ah batteries.
every additional 16.5lb(3 batteries) weight = 10-20 munites flight time (more batteries have cruising time)
Battery technology improved by days. we always expect higher power capacity batteries in the near futures.
warning: 3 x 45a Breakers will NOT work with 2Ah or 3Ah batteries, minimum request 3 of 4Ah or plus batteries.
