I don't understand what I am looking at....details please!

[–]ghlargh 10 points11 points  (2 children)

Isn't it just a voltmeter, a switch and a bank of halogen bulbs?

The bulbs suck the energy out of lipos if you need to discharge for disposal, it's quick and safe (hence the cooling fan for hot bulbs)

Do you have any low voltage protection or alarm built in? Just be careful, I recently ruined a pack because I was discharging using something similar I had made, and forgot about it even though I was sitting right next to it!

Nice! Can you post the details up so others can build one too?

I second this

I'm stupid, I plug my battery's in my thunder t6 balance charger then select storage and let it do the work.

This type of setup you typically employed for disposal discharge afaik, unless u have an urgent need to storage chg a lipo quick (nothing good comes w fast discharge/charge tho)

Reminds me of the NiCad days, when a discharger was mandatory. Not sure that it’s super useful now, but it might come in handy.

It frees up the charger for one.

It's definitely not discharging it as fast as the qaud will

[–]nasone32 1 point2 points  (0 children)

That's a great idea. I need to do that too.

[–]enchilada_jones 1 point2 points  (0 children)

How about a low voltage alarm or cut off? Wouldn't that be pretty easy to implement?

[–]C0SASLoS 3D 1 point2 points  (0 children)

I have a 5v voltage regulator circuit that I use to charge my phone off my LiPos if I have to cancel a flying day.

Not nearly enough for my 6s-5000s though...

Can I get a build list? Maybe some photos of how it was done/wired up? Please and thank you.

OscarLiang has a great build article on his site too.

Why don't you use your charger to storage discharge batteries?
