Default NiMh Super cub question

I got 2 batteries with my SC and one is fine and the other seems to only hold about a third of the charge. The batts. are 8.4v 1000 mAh. Will 8.4v 1400 mAh be ok for the super cub? Will the plane fly longer? Any problems? Thanks, all the best, Sideways

I have the super cub and have 2 of the 8.4 and one 9.6 with 1400mah. All of my batteries work but the 9.6 with 1400 runs longer and has more power.........I get about 14 minutes on the 9.6 flying it pretty hard!!

Should be no problem!

yeah, i would like to go to the 9.6, but im a little concerned about the fit and extra weight vs. power and price. I see the 8.4v 1400 for 15.99 at all-battery .com, thats why i was wondering. Thanks for the reply! Sideways

if your going to buy another battery, this one looks good. http://www.all-battery.com/index.asp...ROD&ProdID=490

the 1 extra cell adds a lot of umph for very little weight

Go for the 8-cell-makes a noticeable difference. Is a bit more of a hassle to get it in/out. All-battery has decent products and cheap prices (got a couple 7-cells). cheapbatterypacks.com is a little more but their batteries just seem to work better-much better throughput. I was amazed that there would be that much difference.
FWIW I built my own 8-cell pack out of 900MAh NiMh for the experience and it's pretty lousy. Charges OK and shows good voltage. Put it under a load and it sags badly and just doesn't produce. Simple voltage is only part of the picture.

If you turn the 8-cell on its side with the wire coming out of the front (toward the nose) it fits in easily. You just "roll" it in place.

I have an 8-cell 9.6V battery for my Super Cub and just got the Parkzone 1.8A DC peak charger. Does anyone know where I can find information on the proper amp setting for the Hobbyzone 9.6V battery on the Parkzone charger? Thanks.

Charging depends on the goal to some extent. In general slow charging if you have the time is better for the battery. If at the field and want the battery cycled you can crank it up.
If in doubt keep it set at about the same or a little less than the MAh, ie. for a 1200 MAh battery set at 1.2 Amps.

For a brand new battery it seems to be a general consensus to charge it at the slowest rate available, use a bit easy for the first few times. After that you can be more aggressive with charging and discharging.

Yep, I sent a good few nimh batts south by using cheap high rate chargers, and not taking them off in time. That alarm clock crap don't get it.
Nicads do well with abuse but nimh batts don't. They're fussy and like a proper charge cycle.

I had a battery that had the same characteristics. I discharged it as low as it would go, then charged it again. It worked much better. Good luck!
