    Battery tray adapter

    Getting my XMaxx ready for its maiden voyage. (Pick up ESC for LHS tomorrow - never ran the VXL-8s figure I can sell it better if never ran)

    Batteries I picked up (unsure of forum rules don't know if I can name non Trx stuff) were a bit short in all ways. Picked up some 1/4" marine plastic cut it to the tray size, added the foam spacer that came with the truck, added a 1/16" foam sheet to the bottom and blam, battery fits nice n snug with the factory clips.

    Just need to convert all to newer plugs and we are set!

    If you go to Traxxas Spartan battery straps for your Xmaxx, you can do whatever you want.

    This seems smart, and lighter weight to boot! Are they up to holding in a 4s pack at high impact speeds seen during bashing? I assume they must or you wouldnt use them, or maybe you dont bash?

    Straps are held in by cutting a big V and putting them under the battery side plates?

    I have a hoped-up 6s system, and use large capacity 3s batteries that are about the same size as Traxxas 4s batteries. I'm a big basher, and a reasonable jumper (I don't jump over my house and garage). I have never had one of my batteries come loose, and I've had my Xmaxx since when they first came out.

    I did a post on how to install them a while back. If you can't find it let me know. If I can't find it I'll post them again. As far as the length of the straps; I cant remember, but it's not hard to measure them out.

    Not trying to be negative here, but what I like about my way (rather than bolting in the straps) was I didn't need to drill holes in my chassis, I didn't need to add any additional parts, and I had smooth (no nuts) surfaces for my batteries to rest on. (IMO) I like your bolt-in way (you did a nice job), but I would use flat-head screws and counter sunk holes on the battery side of my battery trays. Doing so, will let you use both hard and soft case batteries without beating them up as they lay in the battery trays during bash sessions.

    When I made my CF plates a year or so ago, thatís what I did. Countersunk first sure. It would be an easy modification.

    Hi, thanks for your kind response, I appreciate this very much, Ņif it's possible you post again?, I try to find the older post but has no results. I measure the lenght, it's necessary almost 40 or 50 cm for strap or put two hooked for each battery tray. I try to install maybe this weekend, like very much the idea.

    you put contact cement underneath also, or just wedge the straps under the 2 end plates?

    You should have taken out the factory support while you had the 2 end pieces out, no?

    Yep, get rid of the factory battery supports. Also, you want a little bit more length in the Velcro flap that secures your battery. The more Velcro contact area you have with your strap's flap, the more securing strength you'll have for holding in your battery.

    I donít like the idea of contact cement, Iíve crashed badly and snapped my straps before. Of course maybe Iím misunderstanding.

    I wedge the straps under the end plates, but, the screws under the trays drills the straps and hold them. I have a pieces of foam for the battery holders, more secure with all.

    I understand and like your idea, but, in this moment, prefer to stay with the battery holders too, with the two systems, for me, it's more secure.

    For me, the contact cement is not a bad idea, but prefer drill the straps with the underneath screws of the trays. Of course, this is my humble opinion.

    If you have any doubt about your battery coming out, use some Velcro. I use Velcro in all my ex cars and the batteries are super secured. ( When Used with the stock battery holders.
