Have any of you installed Needswings' Shuriken battery kit?
In my car, after tightening down the battery holder on top, the battery is still really loose. There's no way I could pass tech inspection with it that loose. In fact, I took it out because it's just too unsafe for driving around town. Has any one solved this or have any ideas how I could make it more secure?

If the photo's came through, you can see how much room there is all the way around the battery.

Mine was loose too, so I put a piece of wood (1/2" stained real dark making it harder to notice) between the rubber that comes with the battery and the rubber on the clamp that holds it in place. I'm considering how to make a holder with additional height for the bottom of the battery box. I'll get to it eventually even though I passed inspection. I'd feel better with it held in place at the bottom.

i actually thought the battery went in sideways when i bought mine. after trying it it was obviuos you had to install it the way you have it. so i added a few washers under the mount nut and it tightened it up fine. i also had to shave the space between the neg. terminal were the bolt tightens so it would tighten enough not to come loose.
i would like to see a way to mount the battery sideways at the positive end of the battery box to allow a meth container install in the same area.
i dont drive my car much and without a float charger the battery is dead within a week. with the float charger i have no problems but the drop in amp hrs from 72 to 20 is significant if you dont drive the car everyday

les how about a pice of 3/4" plywood the size of the bottom of the battery box with the center routered out 1/4" the size of the battery? that would allow it to sit in a cradle and painted black almost unnoticable

 

Interesting idea

 

I don't have a router. But those are along the lines I was thinking. I'll get to inventing before long. I don't have a trickle charger either .........

Like your idea. It may be easier to use (2) pieces of 1/2"ply. One with the rectangle cutout for the Shuriken, and then just glue and clamp or screw together. I'd like to mount the Shuriken sideways too for future Meth reservoir. I guess we would have to extend the batt.cables a bit to do this.

 

just need a longer neg. cable but the holdown then wont work. i was thinking 3/4" just cause i have some extra! the 2 pieces of 1/2" would allow it to be cut out with a jig saw and no router needed.

 

do you guys want the rubber spacer to be thicker? im all ears, ask and you shall receive

 

Well, given this opportunity... How about using that material you use and make it the dimension of the OEM Batt. to be placed on the base, and routed out w/ the CNC (can it do that?) to receive the Shuriken Batt. so it fits like a baby in the cradle. This is in addition to the piece you already supply for the top, because it helps spread the load out over the top. This would be quite clean and I'm guessing pass any battery integrity inspection.

 

Thanks Rob! Nice idea Dinasrt. Les? 32?

 

i can make a bottom "frame" out of the material but it would be cut all the way through, there is no way to scale back the waterjet's cutting depth and i dont see holding it in place for a cnc to be feasible.

hmm...

 

I'm wondering if my router w/ a straight cutting bit would work, or make a melty mess? I think it would work fine though. I'd make a jig and would be willing to route out a few or more of these if that's the case. If it works, I'd route one out for the Shuriken centered in the base like we have them now, and another for the battery sideways towards the firewall for those that want the space for a tank/reservoir. We would have to design a different hold down like 32 mentioned for the sideway location. The rubber that you use Rob would be way cleaner than a cobbeled together piece of plywood for sure. Thoughts everyone. Rob, you could send me a scrap piece of that material and I'll give it a go and see how it hogs out, if you'd like. Bob

 

if rob cut a peice of that rubber the size of the rubber of the hold down but maybe 1/2 or 3/4 thicj and you could glue it the the hold down rubber ,or just place it under ther hold down rubber beleave me it isn't going anywhere like this. jim

 

Perhaps; but like Rob mentioned, a "frame" or a floor imho would accomplish both securing the bottom of the Batt. w/ the rubber floor,cushioning it and also provide a cleaner/sanitary install. Seeing the stock Batt. floor w/ the Shuriken installed just doesn't look right. My vote would be for a rubber "floor" to cover up the OEM floor, if possible. Bob

 

i like the rubber floor idea. sideways at the back of the battery box. i have a ton of things on the list for the weekend but will try to see what universal tie downs might be able to be modded to work.
as long as we are at rob i need a line lock that doesnt cost 450$!!!! the evosport is a complete kit but man, its pricey!

 

Use the HDPP material, rout out a pocket or easier still cut out a hole and screw a plate on the bottom.

 

Have router, will route. Also have Shuriken, so will be precise. Bob

 

it might be prudent to see what type of tiedown we would need for a sideways mount dinasrt. i cant think of anyone who would want it in the middle if they could mount it farther back, both asteticly (did i spell that right?) and to allow for another container down the road. that way you only have to route 1 box

 

It's the same amount of routing either way, but I agree that with a clean tie down for the sideway mount like we want to do it would be more aesthetic(I have spell check,ha.) Let me know what you come up with. I'll think about the hold down also. I like the "no new holes approach". Hopefully use existing holes for bolt/screw if possible.

 

Interesting information. I still have the OEM battery in mine.
As far as the support material, I would suggest Delrin (Acetal). You can buy scrap pieces on ebay and they machine really well.
