Status: offline 		Is there a way I can charge two li-po packs with my 989? I got it not too long ago and like it and would rather stick with it then upgrade to a Hyperion or something that clearly states it charges two packs. I am asking because I will be purchasing a new E Revo when they are released and will be running dual li-po packs on it. Would be much faster to have the ability to charge two at once. Thanks in advance

Connect both + together and both - together and then add the capacity of the two packs for capacity purposes.

Thanks for the response and I am glad to hear this. Could you be a little more specific and give me some more detail to how to do this. Say I have 2 4s lipo packs I want to charge up. What would I need to connect them in parallel and such. Would appreciate it man. I want it to be a safe set up. Jeremy

Please make sure the packs are identical voltage so the current doesn't flow from the higher voltage pack.
You will now have a 4S pack that is twice as big (in capacity)

This may also help. http://www.commonsenserc.com/page.php?page=lipo_wiring.html
