Discharger or bank

[jim82]

Looking for the best way to go about discharging without spending a crazy amount of $.

[ray schrauwen]

what voltage cells do you have? All different or mainly 4S??

[jim82]

All different. The isdt discharger crapped out on me.. looking for something better possibly even faster

Wondering if this is worth a shot https://www.progressiverc.com/skyrc-...-analyzer.html

Looks nice. I am trying to replicate the RL Power discharger or a version of it for 4S. All components were cheap from China but had to wait a month for them. Almost done building it, I need more Arctic silver epoxy.

There is a thread somewhere that someone used an old hair dryer converted and it works well!! It came from RC Groups I think?

Something like this?

I must arm a discharger yet. I improvise with lamps of cars type H7 or H1 or H4 that are of 12v 35w / 55w and I connect them in series to download a pack of 6s.
Just be careful with the temperature of the incandescent bulbs.

That's what I'm making.

If you wait you can buy the parts for roughly 1/2 the price or less.

Yea I was looking at parts last night. I may end up doing that make a few

That unit is only for 1S and 2S packs, and is to be used with a iCharger 406/308/4010 unit.

Yep 308 is what I need one for. I probably will end up trying to build a few. I watched a video of someone testing it with more than 2s also and it seemed fine

[ray schrauwen]

I am using two layers of 4 Resistors for a total of 8 and 6 fans. MOre like a big mac. Top and bottom 4 are in parallel and the two are then in series to get correct resistance I wanted.
All 1ohm 100watt resistors. Total R is .5 ohms. Since I do 4S packs mainly, it will pull about 30'ish amps. I have a voltage monitor and will get a heavy contact manual switch for it.

I use small heater/demister units for cars & trucks. Cheap as chips.
Here's a link with some info & numbers if you are interested.
I started with a 24V unit for 6s packs, & then also bought a 12v unit for the 2s, 3s ,& 4s packs.

The heaters seems an excellent idea. But it is not common to find them where I live. I use automotive halogen lamps.
I got 24V 150W lamps to assemble a small battery discharger. Simple.
