Never heard of any issues with the 989. That thread doesn't specifically say what the matter is, just some vague "do not use it" message.
The only issue I could think of is possibly the charging scheme used for lipos. Most chargers use a constant-current/constant voltage algorithm. A very few use some type of pulse charging method. Not sure if this is the case with this charger. Linc, do you happen to know what method the 989 uses?
Edit: According to page 4 of the
manual:

...The unit applies constant current to charge Lithium until the battery reaches 4.20V per cell. After that the unit will apply constant voltage to charge Lithium until the battery is fully charged.

So, pulse charging is not an issue here. I don't know what else would be the issue here.
The thread linked above contains a post saying both Apogee and Maxamps do not recommend the charger. I would call and ask why not. The charger does support charging up to 1.25C, so maybe that's the issue? If so, that seems more of a user problem, not a charger problem.
