You will want to set the charger for a 2s battery an charge at 1c. That is what the paperwork that comes with the battery stipulates. It's also the industry standard.

1) What AC/DC charger would you recommend?

Also, I'm noticing that chargers like the Triton2 and Duratrax ICE are DC only, requiring the use of a power supply.

Is there any benefit to using a power supply with a DC charger vs. an AC/DC unit like the Hyperion?

If you need higher charge rates, the AC/Dc Triton2 EQ has 100watts of output power and will charge at 8amps. This is the only AC/DC charger I know that has 100watts of output power. There are DC powered chargers with up to 350watts output power that can charge at rates up to 20amps. DC powered chargers can have more charger power, moving the AC to DC conversion to another box (separate power supply).

Most of the other AC/DC chargers are 50watt and limited to 5amps. Expect to pay more for the Triton2 EQ, its about $200.

Personally, I like the Superbrain 989, it's DC with an AC PSU. It can charge anything up to 8c LiPo and lead acid batteries, all for around $140.

ROAR has also a set the limit for charge rates for ALL LiPo packs, used at their events, to 1C. So a 5000 Mah pack would be charged at 5 amps. This is purely for safety reasons in the pit areas. Don't ask me how they plan to police that rule. But I agree with working on the side of caution, so I stick with the 1C rate myself. Just gotta plan ahead for the longer charge times.

Here it is in black and white.
