I agree with the other replier's comments. I originally used a Hyperion charger 'till it started blowing fuses in my auto power distribution block (West Mountain Radio RigRunner.) Replaced it, under warranty, with an FMA PowerLab8 and love it.
I use a deep discharge battery and am on my second one. If you use a lead-acid, AKA wet, type of deep discharge battery, be aware that going below about 11 volts, IIRC, could limit you to about 10 cycles; even if you use a desulfating charger. As I field charge 6S 5000 LiPos as well as 3S 2300 LiPos, I opted for an AGM type of deep discharge battery with about 100 AH capacity. I use a West Mountain isoPower unit to keep it charged from my car's alternator through a power plug in the trunk plus, if the alternator is running, then the charger draws from the car battery instead of my deep discharge battery.
There are several brands of deep discharge AGM batteries: Odyssey being the most expensive, IIRC, but LifeLine are less expensive / shorter warranty. There is a third brand, but the name escapes me, at the moment.
The reasons I like an AGM battery are: (1) sealed, so if it tips over in the car, no battery acid spills out and (2) it can handle well over a hundred deep discharge cycles before needing replacement. Given that my battery is often topped off by the car's alternator, I haven't dropped below 11 volts, yet.
If you want info about the West Mountain products, let me know, but the info on their website is pretty good. No connection with West Mountain Radio, Odyssey/LifeLine batteries, etc., except as a satisfied customer.
Hi all, I want to be able to charge my Lipo batteries at our field. We have no power there. 12v or 24v deep cycle batteries are what I want to use. I donâ€™t want a genset, tough. I have a 730i Hyperion charger.
What works? And, how do you figure out how many batteries can be safely charged from a deep cycle battery?>>
