Kudos to everyone on this site as it's a daily stop for us Cub flyers!
I have the Hobbico Mark II field charger and have just converted all my batts and my Cub to Deans after a couple of mid loop failures (thank God for tall weeds around the park).
My stock 7 cell charges at 1.2 amps and charges nicely. I have a 8 cell I got at a local RC auction that seems to accept a charge, but I'm thinking it must need to be charged at a different rate.
Does anyone else have this particular combo, and if so, what settings do you use to fully charge the 8 cell and how long does it typically take?
Thanks in advance!

Charge at 1C or lower for good battery life.
That means > if the battery is 1000mAh charge at 1.0A
For 800 > 0.8A
For 1200 > 1.2A
etc.
Faster charging gets the battery hotter which is harder on the long term life. I charger faster at the field but slower at home.
Voltage is not the issue unless the charger cannot reach that level, like the stock charger will only do 7-cells.

steve just wondering did you install the deans yourself or did you have someone install them for you?
also, did you go with small size deans or large?
thanks!

fly,
i dont know how to solder, but i have a friend who works in electronics who can do it for me. i would think it would be pretty straightforward for an electrician...i hope
i noticed when looking at deans online that the soldering side has a silver and gold tip. what color wire goes to each side of the deans? i think all wires are red and black, but im not good with grounding and stuff like that. the youtube link for soldering deans doesnt work, so i wasnt able to see it. it says the video is no longer available
thanks!

On Deans there are tiny + and - signs. They are shaped like a fat T with the + being the top. Always put the female on the battery side so the active electrical part will not have exposed prongs.
He may know how to solder but make sure he does at least a review of the Dean's technique. Hold the heat to the prongs too long and the plastic melts and the alignment goes bad on the prongs.
It does appear that the link is gone. If you want to PM me your email I'll attach a copy of the video-20MB package.

Don't worry about it i found another couple videos on youtube and I got the basic idea.
I was planning on doing all batteries as female, so im not worried about it. Do you know what side the black goes on and what side the red goes on, or does it not matter as long as you do it consistently throughout your setup?
