I have one of these cheapo "tri-voltage" batteries, but have been reluctant to take it out yet.
I does have long run-time but I haven't tested the noise yet.
Are they lithium ion or lithium polymer?
I just got into rc cars and the big boys all use lipo batteries (with the added fun of torching, fireworks, smoke, explosion)
Are lipo's appropriate for runnin audio gear?
I use Wally-World, LiIon's and NiMh AA's, and have thought about trying LiPo. Do they have (need) voltage regulation?
I built a 12v pack out of NiMh AA's to run my DR-680. (2 sets of 8 AA's parallel)
I need schooling on which flavors of batteries need voltage regulation and why.
