I've read about voltage measurement accuracy probs with the 969 and 977 chargers. Tower's listing that says its lipo capable is dated 12/05. There is an warning not to use the 977 (or 969) to charge Orion lipos that's dated 10/08 so there may be something to the concern about using 977 to charge lipo.

MRCs advertisement for the charger does say its lipo capable - see 5th bullet point -

But where ever I'ver seen this issue raised, there have been 977 users that check in and post they've been charging lipos with their 977s with no issues. Maybe the best thing would be to contact MRC and ask them about charging lipo with a 977.
