RE: Spektrum DX5e and Anylink.
Regarding the charger, the link points to Tower Hobbies and the Anylink. The description DOES say LiFe charger is required and suggests a few chargers.
I have the Triton EQ and it seems to handle just about anything I have, including LiFePO4 packs. They (the chargers) are a tad pricey, however, you do get what you pay for with these chargers.
