RE: Triton, Super Brain 969 for Li-Poly
I know what you mean about charging a battery to charge another but I don't think I'll need to charge the tractor battery very often. I have everything in the garage so fumes are not that much of an issue and I can take the battery to the field instead of killing another gel cell from using that as my fast charge source. Who knows I might change my mind in the future and build the PC power source but so far so good.
On another note... the Triton is pretty confusing and I consider myself pretty adept at figuring techical stuff out. I have a feeling that many people will never learn to use most of the features and that it will be a glorified charger for them.
