Lipo's in your cub. Here are some pics.

Here are a couple of pics of the 3s lipo's I got on ebay for around 20.00 a piece and they affer a good 25 minute flight time with tons of power.

Can you use LiPos with the stock electronics?

[mrmugen]

Yes. Remove the jumper in the esc right next to the ACT plug in. This will set the cut off voltage to 8.8v for 3 cell lipo's.

Can you use lipo with the stock ESC/receiver that comes in the Super Cub

if so, can someone please show some pictures of the wiring if there is any wiring to be done

[polo05]

HOW do u connect lipo batt to the current stock ESC/Receiver of the super cub ?

can some one explain and put some pictures please ?

question back to the top...

Sorry guys. I have been a little inattentive. You can do 1 of several diffferent things.
1. Change you SC stock plugs to deans (and all your batteries and charger)...this requires soldering.
2. Make an adapter to go from the sc plug to the lipo (assuming lipo has different plug)
3. Buy another plug for the stock batteries and put it on your lipo (not recommended).

I really want to use a lipo on my super cub. From what I understand, I can use a thunderpower 3-cell 11.1V 2100mAh as long as I pull the jumper, raising the cut off voltage to 8.8v. This will keep the lipo from overdischarging. The only thing I do not understand is, lipo batteries have a connector that connects to the esc (I think). Please let me know the following:

1) Will using a lipo with original esc and rx damage them?
2) If the answer to number one is no, what do I do with the esc connector coming off the lipo battery?
3) Will the lipo battery damage my 480 motor?
4) Can the connectors on a lipo battery be cut off and use a deans connector instead?
5) If I pull out the jumper, can I run the lipo battery until the plane cuts off with out damaging the plane?

FYI - I use deans connectors on all my planes and chargers.

Thanks for the help.

#1 - no
#2 - a lipo hooks to the esc the same way as nimh, just get the right connectors and attach it to the two wire leads coming out of the lip. the multi leads from the lipo are for balancing the cells while charging, not connecting to the rx or esc.

#3 - no, but longer flight times and increased power may wear motor out quicker

#4 - change both esc battery connector and the lipo connector to deans plug and it will work. Just be sure you don't short battery connectors while cutting them or soldering them. Cut and solder them one at a time to be safe, cover each connection with heat shrink wrap to insulate them (you can get shrinkwrap at ACE hardwares)

#5 - yes

WARNING! Once you go lipo you'll never go back!

1) I do find it hard to believe the stock esc and rx can handle a 3-cell 11.1v 2100mAh lipo but that is great, great news.

2) Just what I was hoping to hear.

3) not a problem since they are only 10.99 each.

4) I will definitely convert the lipo to deans. I currently have deans on my planes, ni-mh batteries and chargers.

5) That's great news as well.

I did call Horizon Hobby yesterday and they told me pulling the jumper will not make the lipo battery cut off in time, resulting in a damaged battery. They were probably just on the conservative side.

Thanks for answering the questions I had listed. I've seen lots of confusion about this topic, hopefully this clears a few.

FYI on my mini's I set my lvc to cut out at 2.8vpc. This equaly 8.4 for the whole pack. It is a bit lower than the SC lvc when jumper is pulled. I have had no problems with the batteries running to that voltage in the last 3 years.

Thanks for the great information. I plan to get a Thunderpower 3-cell 11.1v 2100mAh Lipo battery very soon. This battery will also work well in the E-Flite Mini Pulse XT I plan to get this summer. I will probably go with the FMA Direct 4S Cellpro as a charger. I've heard great things about it.

For the price of that TP lipo your can get 3 enerland's. They are 20C and worth getting. I fly them daily and love them. I have never overdrawn one of them. Check my other post about them. There is a link in the other post too. Peace

P.S. TP lipo's are awesome but the price tag is what gets me buying enerlands.

Great suggestions. I've actually been looking at the Enerland's from your other post. Great price for lipos. Can a stock super cub handle the 1800mAh and 2100mAh 3-cell 11.1v batteries? I realize mAh translates into longer flight time but will the higher mAh batteries do damage?

I like the higher rated mAh batteries because they will be great for the e-flite mini pulse XT I plan to get this summer. I need more planes in my hangar.... as always, thanks for your help...this stuff can get confusing...
