Today I tried my Hyperion G3 35c 4s 3300mah (4s2p) in my UL-1. The added weight and more forward arrangement of these batteries made the boat more stable crossing wakes. Speeds also appeared faster (no room for my GPS). Motor/ESC temps were about the same as before, but the new batteries were slightly cooler in upper 90's. I checked the temperature of my newly replaced Rubycon 1500uf Capacitor and it was 195 degrees... WOW capacitors can get really hot. I can see why the stock UL-1's smaller 680uf capacitor goes bad so easily. Adding one more should make them run a little cooler.

Ten Rubycon capacitors in picture were $12.71 shipped to my door. Thanks Longballlumber!

If you think about it get some temps on deans connectors too. I'm only running 2s 5250 30c and mine were @150 degrees.

You can put the GPS aft.

can you put it in the back of the boat?

[Capt. Crash]

Like this!

I guess I could mount GPS at rear, me forget.

Running 4s 2p 6600mah seems easier on the Dean's connectors than running 4s1p 5000mah.

Thanks Longballlumber!

No Problem, it's a small price to pay for a little extra protection with very little risk invlolved.

Detox, Whats your run time on 4s2p???

[detox]

I try not to run them down to LVC because boat will stutter bump then suddenly stall on water. Then I will have to wade for it. But 6600mah should run longer than 5000mah...plenty long enough for me.

Just to help clarify

The UL-1 Speedo has a SB (Stutter Bump) system as well as a LVC (Low Voltage Cutoff).. The UL-1 SB comes in at 12V and the LVC at 11.6. Just so you know we did not pick those numbers out of a hat.. We have tons of data regarding lipo discharge and also qualified our finding with some of the fastest FE RC boaters in the world.. True!

From our testing we have found about 15 to 25 second from SB to LVC.. more then enough time to get the boat back to shore.

Haivng said that there is certanly NOTHING wrong with only using part of the MAH the batts provide..

Hope this helps

Cool Info...I will test the Stutter Bump and LVC again this evening.

[Capt. Crash]

I've hit the speed bump a couple times and was able to get her to shore before she cut out.

I'm still curious about those dean temps.
