The price point for P50B is dependent on what you deemed worth the extra 30 seconds of flight time. The $4.87 JP40 will give approximately 5min full-throttle on 6s8000 in 80mm Avanti V2..... while the 6s10000 P50B about 5:30

Is more than double the cost for P50B really worth it for general sport use? With ample room in the battery compartment to allow 4mm 3D spacers, the sub-$5 power cells will handle their 50-60A continuous until drained in 4 minutes and stay below 80C without a problem. An 18s3p12000 JP40 pack will handle 180A continuous and burn out the EDF motor long before the cells get hot

Where the P50B would really make a dent will be 14~18s15000 120~130mm 2M+ EDF where full use of @90% capacity of 13000mAh will provide something like 12 minutes

(aka 300A pulls for the 20 seconds to clime vertically out if sight!) and 15 minutes cruising at 60% throttle where P50B efficiency below 20A continuous will maximize more of that usable 4850mAh

Game changers. No more 4 minute timers muahahhahahaha
Giant Scale EDF with $500 16s15000 packs will be less than half the cost of Lipos.... AND will have more than double cycle life, making them 1/4th the investment on packs that will never puff in their long-term service.
