My quick release battery/tray idea
 

After thinking for a bit and a little over an hour of drawing i have some up with my solution to quick battery exchanges during a race.

The design is obviously relies on the use of the specific battery shown, this would be the systems downfall. But if offered as both a kit that includes the tray and battery (with several Voltage and Capacity options) as well as separate packs.

Let me know what you guys think and if you have any questions.

i like this alot, i problem i might see is the contacts that are replying on the spring or latch of the handle could get dirty during a race causing a bad connection which would not be very good.....maybe a design with two connectors poking up from the bottom of the tray right behind the latch, dirt would have a harder time finding it way underneath the pack AND up into the plugs......

yeah this is the first design that came to my head, and though it may need some refining i think the general idea is good. It wouldn't be too hard to swap a battery in a couple seconds with this kind of setup, which would be advantageous for those long mains.

Nice to see that someone have same thoughts in mind
I have same thread http://rc-monster.com/forum/showthread.php?t=18793
Design must be simple just becouse how you will do complicated details?. Even with 3axis CNC you cant do everything.
My key make it so simple as possible. Soon I will post some progress I have some 3D drawings. As soon when 3D drawings are ready I will do details on my CNC

at this point the battery/tray setup that i have posted is purely theoretical. I don't own an 1/8th scale buggy/truggy, race, or for the most part care how long it takes me to swap out my batteries. i was just posting what i thought to be a remedy to long pitstops for battery swaps. it is definately not the cheapest or easiest rout but if properly done this method or variation of it should provide the quickest possible battery swaps for long mains.

I mostly like the simplicity of the design; no possible way to mix up polarity, ease of use, and a solid mount for the batts.

Thats true, but the latch mechanism would pretty difficult (not to mention not very cost effective) to make. I think perhaps something like a toolbox or airlid for a car has and use bullet connectors instead. Maybe have the lipo case make in a relatively universal size so people couple just use there existing lipo packs and just adapt them to the case? The latch idea I was refering to is just a notch on the top of the front or side of the pack and a latch that catches it and flips down, like alot of the plastic toolboxes use.

Oh, and Serum was working on a really simple, yet effective design quite a while back. Can't remember exactly how it worked though.

Nice drawings there shizzon :great: Keep it going!


There was a thread for it with drawings and everything. Not sure if he actually build one though. Dunno what happened to it, iirc serum had some thoughts to put 'em for sale in here or something.. Can anybody find that thread? I tried to find it but nothing, maybe it was on the Temp forum what was here sometime ago?

Not sure to be honest. I thought he had started a new thread about it, but I couldn't find it. Maybe it was in a current thread on something else?

Thanks Hardstyle!!! I love creating and inventing stuff like this, thats why i know that being an engineer is a good career for me!

Not only does he have good ideas but also is a good seller I purchased some stuff from him and he followed it up with a call to make sure all was ok with the items thanks your the SHIT I meant the SHIZ

To me it would make more sense to create the quick release system that just uses trays, not specialized hardcase lipos with the mechanism built-in. The design would be the same, except rather than a hardcase pack it would be an open top tray with a velcro strap. You wouldn't have to worry about making any electrical connections quick release, and people could just buy extra trays for however many they needed.

If I was looking at buying something like this it would be a big turn off to me if I was limited to buying the specialized packs and couldn't use my existing packs.

Could maybe have a hard case that you put the batteries in, instead of buying the whole battery with that hard case.
But I suppose that would probably make it bigger, heavier and more expensive though eh?

I don't think so, it could just be a normal battery tray (just like the ones available in the RCM store) but it would have the tab and clip system on it for engaging the quick release base.

I was thinking of a normal hardcase lipo, with the built in female bullets ( 2 or 3s I suppose ), inserted face down into a special tray that had matching male bullets built into it. You'd get an instant connection that was capable of supporting high currents without any extra adaptors required as such ( bullets in the tray could be dirrect soldered to the esc wires if they are long enough ). All you'd need is a simple retaining bar that could click or slide into place, something likemthe way the emaxx 3905 ones do for example- would make for quick change overs as the bullets would be lined up perfectly everytime.

Vaguely similar to the sketch above, but without requiring special lipo cases as such- you'd just be tied to one brand or size of hardcase lipo, but even then you could in principle have a case you can open up and insert new batts inside, then solder on the power wires to the fixed bullets that are part of the case and seal it up again.
