Looking for the best way to go about discharging without spending a crazy amount of $.
Looking for the best way to go about discharging without spending a crazy amount of $.
what voltage cells do you have? All different or mainly 4S??

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?

Going to give this one a shot https://m.ebay.com/itm/40A-Lipo-Batt...9783%7Ciid%3A1

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.
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
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.

See the danger. THEN DO IT ANYWAY!!!

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.
I did end up getting that one from eBay to try. It has 4 fans I hook them straight to the power supply. I've now cycled every battery I own with it at 20a and it works awesome. I also ordered parts from China to build a bigger unit but I'm sure it will take a month or so before they get here.
I gave up lightbulbs when we transitioned from Nimh to lipo.
