11.1 lipos on UL-1

[slyman]

Has anyone tried a couple of 11.1 lipo's on the UL-1? Could I use the stock motor and ESC?

I think the max you can use is 5s (one 11.1 volt 3s pack + one 7.4 volt 2s pack = 18.5 volts).

You'd fry the ESC pretty quick, and it would not be that good for the motor either. There is really no need to do it, you can go faster than the hull can handle with 4S.

We had TWO club members at different times put TWO 4S packs into stock SV27s... thinking they were wiring them in parallel... They were REALLY, REALLY fast for about 30-seconds... A couple of the few SV27 ESCs I've ever whitnessed failing...

The UL1 is PLENTY, PLENTY fast on two 2S packs (4S).... you'd be better off learning to tune props if you need more speed...

I was a newbee with an SV-27 and 2S lipos. I knew I was in trouble when I brought the boat in and the batteries were twice there normal size almost too hot to handle.

I did some research and ended up changing the stock ESC with one from a Blackjack 26. Boat runs great with new 2S lipos and the BJ ESC but feeling the need for speed I got a couple 11.1 3S lipos and the boat really rips. I ran it for about five minutes with no problems. This was the last run of the season befor the lake I run on froze over.

Over the winter Mrs. SANTA got me a UL-1 and I was wondering if I could do the same type of setup on that.

Every post in the thread has told you no. Why do you even bother asking? Do whatever you want, good luck!

Hook those up in series and plug into your voltmeter and report back as to the voltage you get. You'd be suprised?

Fluid, you have my sympathy. Unfortunately, a lot of the young turks do not know who you are and the experience that you have. Jay and others, if these people do not want to take some advice, which will enhance their initial FE boating experiences. What do you do?.
I suggest that a person seeking advice, receive no reply, unless they have stated the basic facts to the area they are questioning...hulls...motors...ESC etc. and then their goal and are you a newbie on the topic!

Yes you can use 2 3S packs,,you can also hook up Qty 2, 5S packs in series for 10S total.....Run times may vary.....

10S? Not a chance.

Maye a 2s and 3S in series but that would be max.

[Darin Jordan]

I know what I'm doing, and this thread confuses me...

Look... the boat and ESC were designed to run 4S... You MIGHT get away with 5S, but you would be money AND performance ahead to just spend $15.00 and get the right prop, then tweak and tune on that... THAT is where you are going to see the most performance gain...

Understand as my post was intended.

For this setup, It's best to hook up a 12V deep-cycle RV battery to the transmitter
to prevent any damage to the boat's electronics as well as eliminating any run-time worries.

Maybe the flag in the post would be better.

Would have thought that most people could have figured that out,,,,oh well.................
