The standard Triton Tanks (T2s/CE5s) use 2.2 ohm heads, while the Triton Battery are 3.7 volts (could be around 4.1-4.2 off the charger) and I never had a problem with using 50/50 eliquids in them.
After filling the tanks, it's recommended to let them sit about 10-15 minutes to let the wicks soak up the eliquid, and use primer puffs (non-powered) to aid initial wicking to the coils.
