malmaz Posted April 6, 2023 Share Posted April 6, 2023 I am after buying a new charger to supplement the one I have, I am after a dual output charger that would be suitable for my 6s 5000mah lipos, I have been looking at the ToolkitRC M6d charger, my question is would I be able to charge 2x6s 5000 mah lipos at 1c at the same time? also do anybody recommend any other dual charger to charge the above?.

john stones 1 - Moderator Posted April 6, 2023 Share Posted April 6, 2023 Chargers are not my strong point, any advice for Malmaz folks ? Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted April 6, 2023 Share Posted April 6, 2023 Answer is yes. M6d can supply 500w output. Divide this by your pack voltage which is approx 25v Means the charger can output 20A total. To charge your 2 5000mAH packs you will need 10A at 1C charge rate. 1 Quote Link to comment Share on other sites More sharing options...
Philip Lewis 3 Posted April 6, 2023 Share Posted April 6, 2023 It certainly should do what you want, specs say 250 watt per chanel and 24 volts X 5 amps is only 120 watts so should do this comfortably. I don't actually have any experience of that particular charger as I use HOTA 4 chanel chargers to charge 4 5000 mah batteries at the same time. Obviously you'll need to couple it with a fairly powerful power supply though to get the full power out of it. Phil 1 Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted April 7, 2023 Share Posted April 7, 2023 I use an ISDT D2 charger, which would also seem suitable, but I'm not sure about it's max output. It's very user friendly and seems to be great in my experience. Keith B Quote Link to comment Share on other sites More sharing options...
malmaz Posted April 8, 2023 Author Share Posted April 8, 2023 Thanks for your reply's, I think I will go ahead and purchase the toolkitrc M6D, for information I have a Dual output 1000w power supply so I think that should be ok. regards Malmaz Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted April 8, 2023 Share Posted April 8, 2023 As an alternative the GensACE iMars has similar specs to the M6D Quote Link to comment Share on other sites More sharing options...
malmaz Posted April 12, 2023 Author Share Posted April 12, 2023 Sorry for another question regarding chargers, I purchased the Toolkitrc M6d dual output charger my question is about the input voltage. My power supply is a Hobbyking dual output 540w (not 1000w as in my previous post ) I have had this power supply many years and pleased with it, the output voltage range is 13.8 - 18v and is set at 18v the new charger input is 7 - 28v if I charge 2x6s 5000Mah at 5a each will the 18v output of my power supply be sufficient ? Thank You Malmaz Quote Link to comment Share on other sites More sharing options...
Philip Lewis 3 Posted April 12, 2023 Share Posted April 12, 2023 Your power supply is 540 Watts at 18 Volts so 540/18 = 30 amps which is all the charger can handle anyway (chargers are basically current limited as to what they can handle). Lets assume your charger is 80% efficient (which would be pretty poor) then 540 X 80% = 432 watts or 216 watts per chanel. 216 watts /25 (nominal) volts = 8.64 amps so will be able to output the 1C charge rate of 5 amps you want with cpacity to spare. So the answer is yes. Quote Link to comment Share on other sites More sharing options...
malmaz Posted April 12, 2023 Author Share Posted April 12, 2023 Thanks for that Philip, my other charger I have is a single output which I have been using to charge my 6s lipos, would I be able to use that at the same time as the new charger so I would be charging 3x 6s at the same time or would that be too much for my power supply?

Philip Lewis 3 Posted April 12, 2023 Share Posted April 12, 2023 (edited) Well reversing the above 5 amps at 25 volts is 125 watts divide that by 80% to account for power losses =156.2 watts X 3 = 468.75 watts so yes it should do but with not a lot to spare, you can expect to hear the fans running like a jet engine (or more accurately like an EDF) though. Worth noting that you can't do any damage, if your chargers want more than 30 amps (say you wanted to charge at 2C) then they will simply be power capped by the power supply anyway which will only supply 30 amps even if the chargers can handle more, you can't drag more out of it than it it is able to supply, all that will happen is that your charges will go to the maximum they are supplied with by the power supply. Personally I prefer to run power supplies conservatively as running flat out may well be techically OK but will likely shorten their life, you can make or buy really powerful power supplies made from used swapped out servo power supplies quite easily and long term it might be worth while doing that..

malmaz Posted April 12, 2023 Author Share Posted April 12, 2023 Ok once again Philip thanks for that, I think I will stick with the new charger for now and perhaps get another power supply in the future. Regards Malmaz Quote Link to comment Share on other sites More sharing options...
