Which discharger do you like guys?

[ActionJackson]

The RC’s are best option obviously haha.. but sometimes timing doesn’t work out.

My little handheld LiPo checker discharges at such a slow rate it’ll take all day to discharge a full battery to storage charge.

Anyone have any recommendations for a faster discharge option where you can select discharge/storage voltage, and maybe even discharge rates for 1 or 2 channels in parallel?

Thanks!

Put RC up on blocks with wheels off ground. Tape trigger on tx wfo. Turn on tx and rx. Return in 15 minutes. Never worry about discharging again! I've done this.

My Hitec X2 dual channel charger just finished discharging a 6000mah nearly full 2s battery to storage voltage in about an hour with a discharge rate of 2 amps. I can set the amps higher, but I don't push the limits on charging or storing my batteries. The longest discharge time I can remember was around two hours on a full 6s 6000mah battery.

My brother has an ISDT Q8 charger which has a DC Output option, you can basically power anything within 1-34v output.
We've used it to power the diesel heater in my shed, or simply power a couple automotive bulbs at ~100w a piece.

Man, that's just unnecessary wear on the rig. I mean, I guess that would work, but I wouldn't stress my rigs that way.

Only done it once or twice. Usually just drive around backyard letting bulldog chase it.

Don't even have to tape anything, just turn up the throttle trim until it goes by itself!

I use one of the ones linked above.

If you have emergency needs for small power, get a solar chargeable battery. I discharge into them, costly discharger but not it's main use.

Example only;y, don't have this one. Do your research if you take this route.

I'll second the ISDT FD-200 shown above. Has worked great for me discharging 2s-6s batteries. I use the app and adjust settings to my preference. Paired it with a P30 charger, pretty awesome combo for me atleast.

Completely forgot to mention I do this, I have a decently sized 5kwh LiFe setup which I charge with excess lipo power. Feels a lot better than simply wasting it on a discharge cycle.

I’ll third the FD200. A couple of times I have charged up and then something came up and I can’t go out and play, or I break something within the first 5 mins and have to go home. I’ll use a balance board to discharge all my batts at once. Doesn’t take long at all. I think it’ll do 25 amps up to 6s

Just to manage expectations, 200W of discharge, at 6S, is about 8A. It could only hit 25A at lower cell counts, like 2S.

My iCharger 308Duo allows discharging from one channel onto a resistive load on the other channel. Like light bulbs, for instance. I modified a cheap hair dryer to act as the load, I can put 500W+ (I think more like 700W) into the hair dryer, whose fan keeps the hair dryer from overheating.

The skyrc bd250 shown above is pretty rad. I can discharge full 4s packs down to storage voltage in less than 10 minutes.

It's so cool, my buddy kept asking about it and ended up getting one too.

 

[LibertyMKiii]

+1 on the skyrc discharger.

I didnt want to need another app on my phone for some other options that don't have a physical interface. This one you set the dial and big 4s packs go to storage within 10 mins or less. No need to put that extra wear on the charger.

I use the ISDT FD-200 Smart and am more than satisfied with it.

I use one of these along with a parallel charging board & a few 5s/63 Balance wire extensions to discharge multiple batteries (same nominal voltage) at once.

Got the idea from this vid & it appealed to me as a tinkerer.

Works really well. Although I do need to extend the wire between the blue box & the black box for managing space.

It's a good timer for me to pack up & stop fiddling with the RCs when it finishes discharging.... AKA when the nightlights go off

Also a soda can inverted & cut with an a hole to cover the halogen bulbs, allows me to use the can as an oil warmer. I may paint the outside of the can with high temperature paint at some point...

P. S. To the original poster...

Add this to the device you have to upgrade to 150w discharge rate.

I dig the ingenuity!

Ended up with the fd200 and it’s pretty neat how you can monitor and control from your phone. Plus it drains 6s 6000mah from 4.2v to storage charge in only 15 minutes!
