newb esc help

[tlsrcs]

I got the esc in a trade and I am having a tough time finding info on it. Here is a pic. I am wanting to know if it is lipo capable. Also if it will run duel motors on a jugg transmission?? Thanks for the help.

Really? Come on, I typed in LRP AI Runner Reverse in Google and this was the very first thing on the page.

LRP - A.I. Runner Reverse

No LVC mentioned and 18 turn single motor limit.

Team Associated website has the V2 model listed with absolutely no mention of an LVC. If you're going to run a LiPo, you'll need an LVA.

Tower lists the minimum as a 16 turn motor, so if you're running dual motors, best make sure they're both 35 turns or higher.

Low voltage alarm is cheap. Just plug it into the balance plug and set alarm for your cell count and voltage/cell you want to get to. I like 3.4v/cell because the ESC and alarm will still let it get lower. I've actually had it get down to 3.0/cell with a setup like that before.

I run these and have been extremely happy with them:

Hobbymate 2 Cells Lipo Battery Low Voltage Monitor LED / ALARM (HBA2S) | eBay

I haven't used that one. I have the integy one that has the little display on it for voltage. I use it now when I comp to see if the battery still has enough juice in it for another run.

Thank you I saw that site.as well just didn't make sense of it....so I can run lipo just need to retro a low voltage alarm. Is there a max cell count? Or voltage? And I am running 2 integy motors I believe they are 55t or 65t. Could that be the reason there is a noticeable lag when I tried to accelerate?

[tlsrcs]

So that page says 4,5 and 6 cells I am assuming that doesn't mean lipo....? Also says 4-7.2v does that answer my other question?

[Trubble]

A fully charged 6 cell NiXx is somewhere around 8.7-9.0 volts.
A fully charged 2S LiPo is around 8.2 volts.
You'd be just fine with a 2S.




3S would be a gamble. I personally think it'd be okay to go 3S with an external BEC, but not without. I could be wrong, though.

Your LRP ESC will go pop on 3S, I tried it on mine and it went up straight away. I have three in cars for the kids, they are great simple ESC's, but they do have a slight lag if you put them under strain in something that needs alot of power to start moving (MT's, 4wd buggies etc). They are fine in lightweight cars, I have mine in TA01's and M03's with 21 and 23t motors where they are faultless

That is pretty slick - I have not seen that one before. Thanks for the heads up!
