The selling price of our complete pack would probably come out to the ball park of $2000. Definitely not as good price wise, but it could be worth it to have that additional 20+ percent energy density. Also for this pack we are trying to develop new cooling methods. This way we could throw in traditional high current cells like the molicel P42A or Samsung T40. This way people accustom using regular paramotors can really push their electric units without overheating the batteries. It would also allow a lower cost option to those who don’t care for the extra ~13 minutes of flight.
I haven’t seen much testing on that either. The 50s cell is the next generation of the Samsung 48x cell which is rated at an insane 3,000 cycles before hitting 70% capacity(this is w/ discharging to 3.0v charging to 4.15v). The 50s is also used mostly in applications such as power-tools, electric lawnmowers, and E-vehicles that have traditionally used batteries with a good cycle life. So we have hopes that under typical E-ppg conditions it will have a decent cycle life, but once again we are not yet sure.
As mentioned before up until very recently the availability has been almost non-existent and even now it’s not great. We have been talking with a few suppliers and believe we can get a solid supply of these 50s cells.
As you have mentioned many times, much of what we are working on is unproven and is risky. On the other hand, if it has the possibility of pushing the development of E-ppg it is worth it.
