    Sidewinder Sv2 questions

    I just got my new Sidewinder Sv2 all mounted up and ready to go with my stock brushless VXL motor. When I hook it up with one battery pack or two in parallel connection, it works great. When I try and hook both batteries in series it turns on and connects to my transmitter okay, but I don't have any movement. Just a red light flashing. Servo still responds fine, just no go. I've tried changing settings when I hook it up to my computer with the Castle Link program, but still no change.

    Any suggestions? Anyone have any ideas or solutions? I'm new to the Castle products and can't find a fix.

    Thanks!

    I dont know what kind of batteries you are using, but the Sv2 can handle 12V. If you put 2 NiMH's or 2 2S lipos in series, you go above that.

    Oh my bad, they are MaxAmps NiMh 7.2v 1600 6Cell. But I'm having the same problem with the stock 7.2v traxxas packs as well. Batteries are fully charged and work great when not in series. I never had this problem with the stock VXL esc running in series.

    Yeah I dont know for sure but my first thought it the SV2 has some sort of over voltage protection and you are tripping it by attempting to run it on what it is seeing has 4s or higher.

    I'm almost certain there is a fix, I just cant find it.

    In this video, the guy runs two 7.2v 1600 packs in series, and this is the exact esc/motor I'm running.

    Maybe he switch the lipo cutoff protection off.

    Edit: the guy on the youtube vid is using an old Sidewinder.

    Lol I didn't even notice that. Shoot. I would think since this is the newer version it would handle the same if not more. It's gotta be a setting I'm not doing right.

    12.6 volts is the limit - the same as a fully charged 3 cell lipo. if you want to go faster, you'll have to look into new batteries - there are 8.4 volt 7 cell nimh batteries available for the merv if you don't want to go lipo. it offers a better combination of speed and run time (in parallel) compared to 2 stock batteries in series.

    there must be a reason why the newer one has a lower limit, and i think it may have something to do with reducing excessive heat or reducing the risk of burning the esc out.

    if you really want to try 2 nimh's in series, you can try turning lipo mode off. by default castle esc's are on automatic lipo mode, to automatically set the low voltage cutoff. the 2 series batteries might work with this turned off. instructions will be in your guide.

    Castle is a bit weird when it comes to specifications. The sticker on the Sv2 says 15V. They rarely give amp specs, at least not stuff that comes in the box, but in some manual they all of a sudden do.
    Jacob, I wonder if you have lipo cutoff switched off now.

    2 x 6 cell nimh packs in series would be around 18v and would not work

    9 cell nimh (what they spec it for) would be just over 13v

    Where do they quote amp specs ?

    At my LHS I found a "2011 Product Catalog" where all the ESCs are in with an amp rate.
    Both Sidewinder SCT and Sv2: 55 amps (full throttle continuous operation with cooling airflow)
    Mamba Max Pro: 70 amps
    Mamba Monster: 120 amps

    Funny: on the same page showing a picture of an Sv2 which says "15V max", they specify "Up to 12V max".

    Was it a Castle catalogue or just someone guessing ?

    Have never seen Castle make any such suggestion

    Was always under the impression limits were higher than that although the burst rating is probably more important

    It is certainly a Caste catalog. I will scan some pages and put them somewhere to view later.

    I scanned some pages. It's the front, back and the two Sidewinder pages. Look here.

    Edit: I see it got an empty page... sorry for that.
    Other articles in it: Mamba XL with a test in a Baja, ERBE test and a lot about the new ICE ESCs.

    Thanks for that mate, interesting stuff indeed

    Not sure what those figures mean when selecting various motors

    Most welcome. Kinda amazing how a company that makes such great hardware, is not consistent in the information they supply.

    By inconsistent I take it you mean the differing voltage limits posted ?

    Yeah. Even on the very same page there is at least some contradiction.

    Yeah definately some inconsistency there I agree

    The Castlelink software has a demo mode in which the Sidewinder SV2 / SCT has a 4s LVC setting yet owners have indicated the ESC will just not arm with the higher voltage

    They used to list the older Mamba Max as having a 3s limit but it also had a 4s LVC setting option, and ran 4s without a problem

    Can someone knowledgable maybe give castle a call? This contradtiction is very misleading... 3S max is 11.1V (12.6V) and 4S is 14.8V (16.8V) So which is it???

    Nobody has suggested that it can run 4s, it will go into over-voltage limit

    3s is the published lipo limit

    They are borderline coping with the amp draw associated with 3s so 4s would be asking for trouble

    If you want to run 4s get an MMP

    MMP is rated for 6s lipos mate

    4s in a small light car is a walk in the park

    Thanks guys, looks like I'll either be tossing this esc out and getting a MM or trying out lipo's. I'll probably put my sidewinder in my 1/16 KB Fiesta and get a MM combo for the merv.

    Thanks for all the help, this is my first experience posting here and you all helped greatly.

    The 5700 CMS36 is rated 3S max. Nothing is impossible, but some things are just not smart.

    i ran my 7700 kv motor on 4 cells... that's something i definitely won't be doing again any time soon until i can find a silk smooth surface and tyres that won't disintegrate at that speeds.

    i'll miss those proline road rages... they never stood a chance.

    not sure if it affected the Sidewinder line, but the Mamba firmware that prevented overvoltage was fairly recent. Try downgrading to the oldest firmware and see if it lets you run 4s (out of warranty). You have the SV2 so you may be out of luck, but try anyway.

    i just thought i'd post, i received my mamba max pro from repairs today - it got replaced, and castle seem to have done a slight revision. it's got a new fan with the castle logo in the middle and a slightly different matte body (instead of glossy).

    the new designs aren't even shown on the sct edition, so i'll see if i can upload pictures. i'll also try and find out if any specs have changed (hopefully not, or for the better)
