RE: Triton, Super Brain 969 for Li-Poly
Of the chargers you list, only the Triton is capable of charging LiPolys.
The 969 may claim to charge LiPolys, but the method by which it charges LiPolys, it has many experts worried. According to the instructions, you're supposed to do a modified NiCd/NiMH charge with a fixed capacity. People that have tried charging LiPolys with a charger in NiCd/NiMH mode in the past have met with problems.
