Wasn't an icharger involved with this fire? Are we sure that the fire was completely unrelated to the icharger? I wonder if any pattern could be established between either the brands of lipos and/or models of chargers involved in fires. CellPro for instance makes a big deal of being a "safe" charger. They are what I mostly use and I like them, but I couldn't prove that they are necessarily any safer than others. I'm sure you could program any charger wrong to start a fire, but assuming you programmed correctly, I wonder if there are some that could malfunction or that have default settings that stress battery packs more than others.

Buy the FMA MPA(around $65-$75 I think) parallel charging board. Its the safest way to prallel charge. Fully fused, both balance tap and line voltage wires.

A PL6/8 and an MPA board is a pretty safe way to charge batteries.

All for the MPA Board ... have one myself ... but would its fuses prevent you from overcharging a cell of a healthy battery if one of the other batteries that you are parallel charging has a bad cell? Still safer to charge individual batteries individually, right?

No. it won't. It will prevent the bad battery from discharging into the other batteries if it shorts.

If I may make a suggestion for a new charger...

Hyperion EOS0720i.

It's programmable and features loads of safety features. A capacity cutoff, a charge time cutoff, and a temperature cutoff.

I have mine set up for 50 minute cutoff, to end at capacity set in the charger, and (if I used a thermistor), temperature cutoff set at 40 deg to help prevent thermal runaway.

Oh and.. you can update its firmware via USB.

Default Something to consider on para-boards

I have two of the Buddy-RC paraboards, and I loved them when I was using them.
But when I built a divided fireproof box for charging, it became difficult to connect the batteries to the para-board.

You could buy extenstions for each charging port, or go with the para- cables.
You will likly need and extension cable to reach your batteries if they are standing on end.

Just a warning if you end up with a charging set-up like mine. But the boards are nice boards,

Dan

You can see from the picture, that the paraboard would be hanging on the side of the metal box if you did not have some cable extensions. I have extensions for both the charge and balance cables.

I like your idea with the fiber board and ammo can so much I’m going to steal, I mean borrow it. So thanks for posting. My ammo cans arrived today. I’ve been thinking about how to do everything and one thing you might consider:

If you have a battery starting to spark or smoke you’ll probably want to grab the whole box, batteries and all, and make for the door. Of course to do so you’ll need to disconnect the batteries. You won’t likely do this on the battery side (each individually) you’ll probably want to do this either at the charger or the cable extension going into the squid. This leaves a problem; you now have bare connectors not only next to each other, but near a metal box as you’re trying to dash out the door. This could be problematic.

I think I’m going to cut the bullets off my squids and replace with an EC5 connector. I have a single charge lead with a male EC5 on it already, this should work as an extension and help eliminate ruining all batteries due to a short, while trying to save them from a fire.

I was wondering if you charged with a lid on this setup. I want to build one of these as well when I can order the amo can and the other necessary items.

I used stuff I already had and can now charge inside a tool box with 6 separate chambers with the lid closed. The charger stays safely outside the box. I feel much better about this setup. I keep it on an unused fireplace hearth to charge inside the house. Now I'm wondering if I should at least add a fuse or circuit breaker in the main leads to save my charger if something should go wrong?

I can travel with this setup in fact I wouldn't hesitate to use it in a motel.

My 2nd place to charge is my unused gas grill. I took that for a trial run this evening. I think I could feel good about using that in the garage and definitely outside, I just don't want my charger exposed to the weather you know. I don't won't the cats jumping up on the grill and knocking my charger and power supply off. Gotta figure a way to cat proof that. LOL!

There are those rare days when you try to get flights in between showers and charging outside with it raining wouldn't work to well.

I'm glad leaverus brought this thread up, I feel much better about my charging stations now.

.
To be honest, I am a little fuzzy on exactly how I disconnected my battery when I had my fire. I remember hearing the smoke alarm, looking into the garage, and seeing what looked like a little camp fire on top of my bench. I rember going over to it, andi it was just burning slowly like some wood scraps. So I went to a shelf, grabbed a plastic bucked, and "I Think I lifted the burning battery by it's wires, and put it into the bucket, ant took it to the front of the garage and truned on the faucet. I don't remember when I unplugged stuff, but I know that I did.

I guess my point is that the fire was slow buring, so there was a little time. I think a EC5 connector on the charge lines is a good idea, but you still have good batteries connected in parallel.. The balance cable is easy to unplug.

You should run through this scenerio in your head so you will already have a plan.
I might just pull the good batteries out of the box, and then put the lid back on.
With the lid on, the battery connector is still accessabel, and could be unplugged.
And the fire is under control.
I am leaning on the side of getting the good batteries away from the burning battery ASAP.

My main advice is to run it through your head as to what you would likely do, so when the time comes, you already have a plan.

Dan
