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:
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.  |
Wow, thanks for the info! Upon further investigation I found a post that discussed this issue. It sounds like you were correct, as someone stated:
The super brain can possibly damage Lipo batteries, "because of there micropeak technology which another words it charges with a pulse instead of a constant current which is supposed to be bad for lipos."
But like you said, the manual says differently, so im guessing it will be ok to charge Lipo batteries...
Hmmm, just looking at the Apogee web site. Here is what I found on the FAQ web page (6th question down)...
"Q: Can I use an MRC Superbrain charger for my lithium packs?
A: No. We will NOT warranty any packs that have failed while using this charger. We can also tell which packs have been charged with an MRC charger. Until MRC adopts the correct constant current/constant voltage (CCCV) charging schema for their chargers, terminating voltage at no more than 4.2V per cell, we will not endorse their products as being lithium compatible."

Like I said before I am a newb to the whole lipo thing so not really sure what that means, but it doesnt sound good. Haha. Just thought id try to check with the manufacturer like u suggested.
