Switching to LiPo's

Yes. One side would have a 7.2V lipo. The other side would have an 11.1V lipo. Aquacraft, without sticking their neck on the chopping block, pretty much told my LHS that the SV27 ESC should handle it with a Low Voltage Cutoff. (to protect the Lipos from discharging too far)

Hello all. I have a SV that has all sock motor, ESC and one set of Venom NiMh batts. In an earlier post someone was stating that holding onto NiMh batts was a loosing battle. I need to order some new batts beccause I only have one set now and would like some recomendations on what to do about switching over. What do I need to do to the ESC, BEC and what size or type LiPo's do I need? I have a 977 charger, how do I charge them and how long does it take to charge? All the LiPo numbers and differences are confusing me. Thanks for any help with this one.Comment

I ran my SuperVee on 5s and it cost me a motor. It was my fault for trying too large a prop. It ran good on a 440-3 and 442. Batteries, motor and ESC all stayed cool until I tried a M445 prop. Ran stupid fast for a short distance and quit. Motor was about 160 and smelt burnt. To run 5s you have to disable the BEC on the ESC and run a seperate receiver battery. Run 5s in the SuperVee at your own risk. Running 4s is not a problem. You should run a Low Voltage Cutoff with any Lipo in the SuperVee.
I didn't inquire about the motor, just the ESC since I run the Ammo. It's still good info though. Thanks."A quick temper will make a fool of you soon enough."

How do you like the Ammo? Did you get the 36-50-2300? I was looking at the Ammo 36-56-1800 and a Hydra 120 to see how that goes. According to the Speed Estimate by Use of Voltage & Constant "Kv" tool the SuperVee should in the mid 40s with a M445.Comment

The ammo made a world of difference over the stock sv27 motor."A quick temper will make a fool of you soon enough."

I charge at the 1c rating, 4000mah pack, charge at 4 amps, since its a 2s pack set your cell count to 2 cells, hit start the screen should say lipo on it, if it dont stop charging immediatly. read your instructions first though it tells you excatly how to do it.Comment

WOW! I just hooked up my sv with an 8XL x447 prop and 22.2V Lipo's. I was laughing so hard I couldnt drive. When I nailed the throttle it would jump about
6" out of the water and the hull never hit water again. I was just a rocket. If the wife will let me ill tape and post sat. afternoon. I was VERY nervous that I would toast the controller or motor but due to excellent water cooling on the CC 80 and ose motor jacket it was just warm.Comment

I ran about 7 minutes, I only checked temps after the run so I didnt have to re-tape hatch. Esc was around 110, batterys were barely warm and motor was around 120.Comment
