Lipo quessies

[Nick]

Thanks,

Since I'm in the UK, I've been looking at these:

My Triton (by Great Planes) can do 4s lipo @ 2.5a max. So I can charge a pack at time. I thought I want to try Lipos before buying a new charger to do them faster or more cells at once, seems logical.

If I did 2.5a for 3300mah, is that like 1.5C? What else would I need to charge, any sensors or anything? Does the Triton detect when it is charged and stop, safety etc?
