    7 cell hump or flat

    I am getting some SPC matched racing packs that are 7 cell and 3800 and I am going to buy them assembled. I know if I get hum I can adjust where the battery is but then there is higher CG. If I get flat I cant adjust where batt is but there is lower CG And more even weight.
    Agree with slowenufs sig wheres the new 4 tec?

    I think a lot of the ppl on here will tell you to get the flat pack because it has less resisitance in them giving of consistency. I would just get the flat pack and take out the foam from the battery box on the truck.

    oK i WILL do that then when I get it... I want to set my slash up for racing and some dirt bashing and in the snow/rain. I have a vxl system and a team oriopn 15t double bb motor... What else should I get that drastically improves handling? (shocks) (arms) whatever it is to upgrade to handle like a star?

    If you are ordering from SPC,I'm pretty sure you need to use a flat pack.Reason being,SPC pack are arranged SxS,so the 7th cell will be sideways and will not fit with the stock battery hold-down.You can run hump packs,but I think they need to be stick packs so that the top cell will be mounted long ways so that it will fit in the slot of the hold-down.

    I think that is your best option.You won't have to use the foam and it will not interfere with the hold-down.Also,as mentioned above,the battery will have lower resistance than if it had those long wires connecting to the extra cell.

    See this: http://monster.traxxas.com/showthrea...ight=pro+match.
    He uses side by side packs hump and then you could use the same battery in other trucks such as Stampede and Rustler if you could or wanted to in the future.

    That is funny that is exactly how promatch does their batteries as well.

    I am not quite sure what spc batteries go for but the promatch go for around $52-54 dollars for matched cells (which is what you want to get w/ traxxas connector).

    The link is www.promatchracing.com

    I'd go for stick, it'll keep the CG a bit lower.

    I woudn't go with stick.I would go with a flat side by side pack for less resistance and lower C.O.G. Besides,SPC does not sell stick packs.
