Default Sanwa Li-Fe radio battery?

So this battery came with my M12s and I've had it for just a few runs. It came with a basic wall charger and I charged it the day I got it. I put it on my reedy 1216 charger today at the right setting and it charged for only 5 mins or so. I put it on my hitec battery checker and it's only coming at 8% charged. So I put it back on the wall charger it came with and it immediately went to green. Checked it again and it's on 4%? Maybe these lips checkers don't pick up life packs? Put in the radio and it slowly dipped down to 6.8v. So it's bad or the checker doesn't pick up li-fe batteries? Seems fine other then the percentage.

There's a Sanwa M12S thread

Never used the wall charger with the Sanwa M12S because I always use my table top 12V charger. Need to make sure that the chemistry is set to LiFe! If it's set to LiPo you are very likely to damage the battery.

LiFe nominal voltage is 3.3V and fully charged is 3.6V. If a LiFe cell goes past 3.6V you'll be toasting it.

6.8V in the TX is fine.
