Yeah, very nice. Can we steal that as show content? We'd give you full credit.
Sure, no problem. But I don't need to be given credit, but if you do my last name is pronounced GING' key. The t is Todd.
If you wanted expound this into a show topic may I suggest the subject of The Economy of High Current Charging. This idea came from listening to James talking about having three batteries and two chargers, and cycling them to be able to almost continuously fly; and batteries are solid fuel. I took this idea to the next step, two batteries and one high wattage/amperage charger for almost continuous flying.
(If you are interested I'm willing to come on the show and talk about this stuff)
I could go into it, but to cut to the chase:
Charging system: $140 Powerlab 6 or $190 Powerlab 8 V2, two 100+Ah deep cycle batteries.
Flight battery: Pair of 6S 5000mAh batteries.
Powerlab 6: 19.5 minutes (14.5 minute charging + 5 minute balancing timeout)
Powerlab 8: 17 minutes (12 minute charging + 5 minute balancing timeout)
1. A lot of inexpensive batteries are rated for 5C charging. So let's charge at 5C, while monitoring battery temp accurately If the battery is not increasing in temperature while charging , we are not doing damage to the battery. After testing with expensive Pulse and inexpensive Turnigy batteries, they both don't mind being charged at 5C
2. $190 Refurbished Cellpro Powerlab 8 V2
40A/1344W charger or $140 Refurbished Cellpro Powerlab 6
40A (~33A @ 24vdc)/1000W charger (need to add a $10 balance lead adapter). Add to this "inexpensive" refurbished charger a pair of ~$90ea 100+ Ah deep cycle batteries.
So here is my charging math for parallel charging a pair of 6S 5000mAh batteries at 5C on my Powerlab 8:
1344watts / 25.2vdc = 53.33amps (I'm limited to 40 amps at 25.2vdc)
40A / (2 batteries x (5Ah x 0.8)) = 5C maximum charge rate.
With the less expensive $140 Powerlab 6 doing the same charging:
1000watts /25.2vdc = 39.68amps (limited to 33A by the 24vdc power source)
33A / (2 batteries x (5Ah x 0.8)) = 4.13C maximum charge rate.
