A few battery questions from a complete newbie to things electrical:
-
Are the Bonka 22Ah batteries (8S1P on the website) the ones that fly for about 40 minutes? Or, is that the ten minute battery, and there’s a larger battery?
-
Is the system voltage 22.1V?
-
There’s a line on the site for the motor that says it includes “Four high voltage 80A ESCs”. What are those? What do they do?
-
I can’t find a picture that shows where the battery(ies) sit in the frame. I would assume low, between the legs. Is it some kind of tray with clamps to hold the battery?
-
If I want more flight time, do I hook the batteries up in parallel? If I remember correctly from college physics, voltage adds in series with constant amperage, and amperage adds in parallel with constant voltage. Do I have that right?
-
Regarding charging and chargers: I assume voltage has to match. Is there a maximum Ah rating for the charger? A minimum? How long does it take to recharge a battery, given an appropriate charger? Is it feasible to take two batteries out to the field and fly three or four times in the day (fly while one charges)?
-
If these batteries don’t ship internationally, can you tell me what to search to find them? I am in china. I guess I’m looking for 22.1V LiPO batteries. Are there grades of quality? Do batteries catch fire spontaneously, or is it usually some kind of overload or damage to the case?
-
What else don’t I know about all this that can get me killed?
