Cases My Charging System

[Heliman450]

Not quite custom made as the system is based upon a stock Graupner charger system. Yes, expensive, but I'm after safety and efficiency following on from a discussion on the subject in our monthly meeting of the flying club.

System consists of a fire resistant document case sitting on top of a ceramic plate to insulate the cupboard it stands on. The batteries sit in the case with a sand-filled 'fire extinguisher' above consisting of a plastic box with the base opened up to allow the plastic bag the sand came in to become the release mechanism for the sand if a fire incident were to occur dumping the sand into the case below. The volume of sand is about 10% more than the case with batteries.

I don't need to get too close to put it out, I just stand back and stop it spreading to the room with a normal fire extinguisher.

Hope I never need it in anger!

Wow, that is definitely something! Mine is just a cheap case housing two 12v 575w PSU's wired in series (1000w actual) with a piece of plexi that the charger sits on. Nothing like this. That is impressive.

Thanks Tony, when surfing the 'net, I saw too many horror photos of the injuries caused by the chemical fire of LiPo's to take any chances. My time as an auxiliary fireman also helped

The most expensive part was the case at $50, sand was $7 and the wire stand $5. I also invested in some storage/carry cases for my stock of batteries as another level of protection. I don't intend to store the batteries in the metal case as that would turn it into a very dangerous item indeed.

P.S. Incidentally, the red, Polaron part of the system can be detached and taken to the field receiving power from a battery/batteries if desired. The box contained all kinds of supplemental cables. That would also be a good subject for publishing on the Forum or adding a link to a website explaining what they're all for.

That is an awesome set up you have their Heliman450. I just have a ammunition holding box that I use. That is also a good idea to have a fire extinguisher near by. I have one in the kitchen but not one next to my charging station. I will have one today that's for sure! Thank you for sharing!

Very nice setup Phil! Extra precautions is a must, I have seen the horror stories and pictures of just how much damage can be done with lipos! It's scary!
