Hi all,
I asked a question a while back on failing batteries and both here and the guy I got them from suggestted that it was an internal mechanical failure of the battery due to shock/vibration.

With the help from a member here who sent me a charging socket I have made a new case following some suggestions also recieved here.

The attached pictures show the first battery and the total pack.

All batteries are now horizontal and are sitting on an old (thick) mouse mat with also a piece of mouse mat between each battery and the case at the rear. The case is made from an old estate agent sign and when folded the batteries are snug width wise. the wood is to protect the wiring from being crushed and the straps holding it down are from ebay (£3).

I still need to tidy the strap length and make it a bit more waterproof but so far it seems okay.

Thanks for all you help.

(the picture of the first battery was taken prior to fitting the charging socket which is why the two wires are heading off to some where else)

Good work on your case Mutmost - I am a big fan of custom made battery packs. It's amazing what you can come up with with a little ingenuity and £2 worth of materials. Well done!

I always thought estate agents were put on the planet for at least one useful reason, but couldn't fathom it out.
Of course! it is to provide battery pack cases.

I hope it is strong enough to withstand all the bumps in road, but I suppose only time will tell.

Did you fit a fuse into the wiring inside the case, as they have in the original?
If not, then it would be a good idea to do so.

Well done,

Colin

Thanks for the comments.

I did include a fuse as per the original set.

(Does go bang though when you try to test the charging prior to putting a socket on:eek: )

I find it is always better to blow a fuse, rather than the batteries or charger that are a lot more expensive. :)
