Running 5s with t180esc ?

[britscoot]

Do i have to pull the bec wire to run 5s or will it be fine?

Cheers

I run my T180's on 6s with the BEC............never once a problem.

[britscoot]

Thanks thats what i wanted to hear!

I have a 5s1p staring at me and i cant resist....lol
I hope i remember to re program the esc in the morning.

Thanks again matey.

one more thing,i run a 2200kv motor.
Do i need to swap that out or will it be ok?
I have a 2000 and a 1800kv motor laying around.

A 2200 Kv motor is probably too hot for 5S. That's over 40,000 rpm = SAW territory. Use the 1800 Kv motor.

BTW, I never cut or pull "the red wire" on any ESC. I use a 4" servo extension with the red wire cut. That way I don't have to mess with the ESC wiring when switching boats, I just plug in or take out the extension. KISS.

Sounds good.
I dont have a jacket for the 1800 so i will try the 2000 for a short run.
dont want to get too close to SAW land.

DO NOT use the internal bec on 5s! You're just asking for trouble.

[britscoot]

mixed opinions on the bec.
How come some people are ok with using the bec?
now i'm worried.

Hi Rum..........i'm curious to know why this could be an issue..........i havent had one problem and have two T180's in 6s boats. I've heard this before but cant figure out what the potential problem could be............can you fill me in? Thanks.

That's a slick trick. Keeps from damaging the ESC wire over time.

for the 14 dollars i run a bec on my t180 at anything over 4s..better safe than sorry in a boat bud! it may be the only real weak link in those esc's so far

Many ESC makers recommend not running the BEC over 4S. This causes controller problems and has been well documented on this site.

However, not all ESCs have this issue. I have used receiver packs on all my non-LSH boats for about forever (20+ years), until I started using Castle ICE controllers. These can use their BEC circuits up to 8S although I've not tried them over 6S. I have no idea of the Turnigy180's ability, it should be stated in the instructions. At least one comment on the HobbyKing site mentions a problem with the BEC over 4S on the T180.

Thanks Fluid............... Just looked at the provided instruction sheet with the Turnigy ESC's.............same sheet from the 25a to the 180a. No mention of bypassing the BEC on any of them for higher voltage.

The 25a and 35a esc's show to have a "linear" BEC mode, while the others(60a and up) show to have a "switch" mode. The only other difference i see is that the T180a has a BEC output of 5.8v compared to 6v for the others.

I'm not going to "recommend" someone to use the internal for more than 4s...........but from personal experience and dozens of runs on 6s with two of them i have had no problems. I'll report if i ever do.
