Power loss a full throttle.

[bobby89]

I am having trouble with my 32" rivercat losing power when i try for full speed. Up to 3/4 throttle works great but as soon as I go full it cuts down to about 50% power and stays that way until I unplug the batteries and start over.
My setup:
32"rivercat hull
Turnigy 2000kv 4074
Turnigy 120 esc/watercooled
2x 2s 5000mah zippy liop wired in series for 4s
X445 prop/ sharpened and balanced.
I am thinking the batteries are bad and the lvc is what is kicking in when I hit full throttle but I dont have my new packs yet for testing. Let me know what you think!
Thanks!!

This is a common problem on some T120 & Seaking esc, they can be oversensitive on the lvc & cut in to soon. Most that have this problem set with no lvc & time runs so as not to go to low on battery capacity. What lvc settings have you tried so far.

[bobby89]

I have only tried 3.2v. I didnt know if I should go lower?

3.0 and raise your strut up

That esc prob wont handle a x445 with a 2000kv 4074 anyhow. Sell it and buy a T-180.
What C-rating on your packs?

[bobby89]

They are 30c

Setting lipo cell count/voltage manually sometimes helps also. ie don't use Auto Lipo.

[bobby89]

I did set it manually, i have the program card. I have tried all timing settings too but that does not change anything.

[martin]

Set with no lvc & it should work without cutting in, i know a lot prefer to time their runs anyway rather than rely on the esc lvc doing it just in case the lvc isnt working properly & ruins cells by going to low.

[dana]

ive had this happen to me before

[martin]

I was using this same esc on my mini mono with a 450 size 3800kv outrunner motor on 3s 2200mah 60c & i coulnt stop the lvc cutting in from the start of the run. Went to no lvc & it works perfect all the time, but cant stress enough you must watch run times.

[bobby89]

What would you recomend for run times?

[dana]

you can still use the lvc if you get the prop outta the water more… am i talking here?

[martin]

With a 5000mah you must leave 1000mah in the pack so when you recharge you put in 4000mah + 1000mah thats already in the pack. You must not use more than 80%.

[bobby89]

So it must be the lvc, i had enough time tonight to get one more run in. I turned the lvc down to 2.8 and i was able to get full throttle for about 4 mins b4 i brought it in to check temps and put it away for the night.
