Battery Strap O ring Hack

Or an alternative way.

This method has two pieces of the O ring securing the battery to the Spark verses just the one.

Roll the O ring to the top and the battery is very easy to change.

Nice cheap fix mate, I have not had an issue with the battery falling out yet, But now I have said that lol.

It only needs to happen once.

But with proper insertion of the batteries, there shouldn't be an issue.

I'm up to nine batteries of the old style design.

The first three batteries, I have been using since July 2017 and they show no wear and fit tight.

I do the Plug and Tug on each battery change.

I trust the battery and the procedure of changing it.

The O ring is JIC.

I wondered if this was a large issue for those batteries that are inserted correctly until they latch well. I've got three batteries and they seem to "click" pretty solidly when I insert them. The only time I would think there would be a problem is if vibration were to "unlatch" a battery since they are pretty solidly latched and I have to pull a bit after unlatching to get them to come loose.

Spark317, I think u hit the nail on the head...
“But with proper insertion of the batteries, there shouldn't be an issue.” Shouldn’t... Cheap insurance to use a strap.

Here is something to take note of

How to unclip a Spark battery without damaging the clips:

Not bad, good use of an o ring bit it's only less than 5 bucks for the battery strap. Only thing with them is the rear prop guards can't be used.

 

[Spark 317]

Only thing with them is the rear prop guards can't be used.

I found that out when I used the clip.

The Spark sort of looked like a flying lobster with only the front guards attached.



I was testing a strobe light set up on the battery clip.

When I used a Dremal tool to remove material from the clip, to make room for the guards, it made the clip too weak and broke after several uses.

Can anybody provide a link to the o-ring they have used successfully. I've been looking and I can only find large collections of assorted o-rings or o-rings made from different materials (they use technical names, not simply "rubber o-ring"). Thanks. By the way, I agree with taking care to make sure the battery is secure, but I'd like that little bit of extra protection the o-ring technique provides.

I used the EPDM rubber rings from Grainger's.

You might try a hardware or automotive store if a Grainger's is not available near by.
They can ship but it costs more than the parts.

The #141 fits tight but you could go smaller if you wanted a little tighter fit. #140,139, etc.

The size of the rings are on the site.

The #141 ring is 2 5/16" ID, 2 1/2" OD.

I bought a Multi-Pack at the local Automotive chain store for $6. It had a couple dozen different sizes in there and only 1 of the one I needed but now I have a box of o-rings if I need one in the next 10 years or so LOL.
