I've been using FD200 for a few years now and it has been one of the best RC purchases for me. I discharge my quad batteries using a parallel board so it doesn't take much time to discharge 20 batteries. BTW, FD200's internal bolts tend to get loose in time. One thing not covered in detail in the video is using the DIY dischargers in combination with chargers that have external discharge option. Auto stop is supported in that way.

@BlackThunderRC 7 месяцев назад

Used the BD250 for a couple of years now. The fact I can use it stand alone or plug it into my laptop and get some decent data is perfect.

@RCVideoReviews 7 месяцев назад

Agreed. The data is nice. Good feature.

@bassohollic 6 месяцев назад

I was about to pull the trigger on the BD250. I wanted something to do some tests on my batteries to see the health of them. What kind of analysis modes do they have?

Well done video on battery dischargers...Just purchased a BD250....Like the simplicity of it and that you can view record the discharge cycle. Only change I made was to the fan. Pulled out the OE fan and installed a Noctua...noise level is near gone.. CFM on the Noctua is a little less but since I won't go any higher then a 10A discharge, it cools it just fine.

@alliaj1 11 дней назад

@user-nc4sb5iw4o what model of the Noctua, pls? THX

Been using a few of the Aokoda 150W bulb-based ones for a handful of years. Can't beat them for the price. Usually ~$20, has discharge controls and cutoffs, per-cell balancing, and no beeps!

@JasonAndrewReid 8 месяцев назад

My favourite discharger by far. Simple, easy, but has now jumped up to $30

@StyleWarZ1 2 месяца назад

To the Admiral. If you also want to use it like the captain dan one, a bridged xt60 connector instead of the icharger x6 would do... or am I mistaken? Also you might want to rethink your coolingfan choice. They are fan and heatsink in one. The air that does fans push nerver really cools your big heatsinks.. at least not activly.

@RCVideoReviews 2 месяца назад

Going to have to disagree about the fans. The amount of hot air displaced by them indicates to me they are actively cooling. Cool air in, hot air out. They're still working fine to this day.

@OraTab 11 месяцев назад

I have both the ISDT FD200 and the SkyRC and will say they’re both great dischargers. The one thing about the SkyRc one is that you have to tinker with the end voltage a bit. It needs to be slightly lower than what you intend because it will reach that voltage with the load, but once you stop the voltage will end up being slightly higher, if this makes sense. That’s the only annoyance with it.

@OraTab 11 месяцев назад

Once again, great video 👍🏼! Thank you 🙏🏼

@RCVideoReviews 11 месяцев назад

One of the guys in the livesream did mention that. I noticed on high amperage settings it definitely does not account for sag, but on lower settings it seems to get a lot closer to the desired voltage level which makes sense. Evidently it only does CC and does not transition to CV.

@RCVideoReviews 11 месяцев назад

You're welcome :)

@lightbulbjim 11 месяцев назад

I also find the SkyRC discharger inconvenient for this reason.

@geoffh7206 11 месяцев назад

Thanks for the comprehensive comparison John. I never cease to be impressed with the clarity of your explanations. To be fair on the commercial dischargers, they do offer quite good discharge power for general use. It depends on the mix of batteries in your stash. For example, both the SkyRC and the ISDT would outperform the "Admiral" for 3S discharge speed, and the SkyRC would beat the "Admiral" for 4S.

@RCVideoReviews 11 месяцев назад

Yeah, that's why I used watts as the measure vs time as watts illustrates peak possible performance. ISDT and SkyRC can vary resistance to reach max wattage where The Admiral has fixed resistance. In any case, Regen discharge beats them all if you want to talk about speed.

@Themlpg73 5 месяцев назад

This is great. I thought the Isdt discharger only works with Isdt chargers, and the same with SkyRC. It's really good to know that it doesn't matter.

@R.B_B 10 месяцев назад

Another great video. Aboit the admiral discharge we can just wire as you made and for use they as a battery killer make a jumper cable between the two ends and connect the battery

@RCVideoReviews 10 месяцев назад

Sure, you can rearrange the inputs. I thought about doing that myself, but I figured if I'm going to kill a LiPo it might be better/safer to discharge it at a lower rate.

@SteffenRC 11 месяцев назад

@nitrovice 4 месяца назад

Thanks John for another great video and tutorial. I wanted a discharger to discharge 6S at 20-30 amps. Now, my M6D charger can only provide high amps when in regen mode. Can I still use the Admiral and set the mode to regen?

@lazydude00 11 месяцев назад

I have two of the BD250s and love them. If they died I'd order another asap. I discharge in the garage so the noise is meh. I do like your hand-built models but I was too lazy to make one.

@RCVideoReviews 11 месяцев назад

I’ve been using the BD250 quite a bit over the last couple of days and I do really like the graphing/analysis features.

@jackgoldberg3201 Месяц назад

Hi John, quick question on the iCharger X6. Could I connect the output from the regenerative charge mode into something that will use the power (like the admiral or captain dan) instead of a battery bank?

@RCVideoReviews Месяц назад

I think in regen mode it might be looking for voltage. I don't think I've tried regen mode outside of a battery.

@marks7445 7 месяцев назад

Amazing what that little iCharger is capable of. I have an RCToolkit M6D which is a dumb version of this. With a good DC source, they are capable of so much. Can you provide more information on those batteries you are using for your charge / discharge station? Similar units I found looked quite expensive. Do you just have them wired in series to the XT60 connector and use that same connector directly for charging and discharging?

@RCVideoReviews 7 месяцев назад

Yes, the iChargers are solid feature packed devices. This video should explain the battery bank: ru-vid.comBm9Bjpb74RQ

@D-Flap_FPV Месяц назад

If you jump the Admiral plug used for the charger doesn’t it become a battery killer now?

@RCVideoReviews Месяц назад

It sure could.

@pazignac 10 месяцев назад

Question on the wiring of the admíral. Is it battery (load) positive to one side of the bank and negative to the jumper (black wire) going into the (charger port) negative?

@RCVideoReviews 10 месяцев назад

Ground from battery to discharger. Positive from battery to one side of admiral and the other side of admiral to charger. i.e. Resistors are in-series with the positive line.

@woofie7520 11 месяцев назад

@RCVideoReviews 11 месяцев назад

@1dirtovalracer 9 месяцев назад

How do you know when there's enough capacity in the battery bank to put whatever battery your discharging into the bank? Does the i charger stop when it can't put any more juice into it? Or do you have to put a volt meter on the battery bank?

@RCVideoReviews 9 месяцев назад

Several safeties: 1) If you start with the bank full, and then charge any number of batteries, any number of those batteries can be put back into the bank. It would be different if you start with the bank full and then start dumping already charged batteries into the bank in which case #2 takes over. 2) The batteries have built in BMS. When the BMS sees the voltage of the battery is peaked, it opens the circuit disconnecting the battery from the discharger.
