Need,powerful,affordable,charger that will do 6s 5400mahs?

[Ironmike340]

need a charger to do up to 6s 5400s. I've looked at up120 on Amazon but not sure what I need. Don't need to be super fast but does need to get the job done would like a dual charger. Affordable.

Thinking this

I recently got this charger from Hobbyking & so far very happy with it. It has 20A 300W & charges the new HV Lipos ($62):

I use this for an AC power supply:

Also for the past few years I've been using the Thunder 020 AC charger (20A 300W). I actually ordered the Thunder DC 620 charger ($80) and I guess HobbyPartz was out of stock & sent me the AC 0620 charger ($129) instead, but for the price of the DC charger + none of those other charges once delivered...good for hobbypartz:

I also have 2 parallel charge boards, so I can easily charge (2) 3S on one charger, and up to (4) 2S Lipos on my other charger. I also use 1 of the chargers to just charge my 6S. Parallel charging is definitely less expensive than buying a powerful dual port charger. This allowed me spend a lot less money a few years ago buying a good single port charger & paraboard, and now recently, buy another good single port charger at a good price. This now provides me with great charging flexibility. It's definitely a bonus when I want to quickly charge multiple batteries, as sometimes we make those last minute decisions to go bashing.

I'm just going to leave this here https://oscarliang.com/choose-lipo-battery-charger-power-supply/

None of the chargers listed will do what the OP wants to do, other than the Revolectrix charger.

In order to charge 2 5400mah 6s lipo batteries at the same time at 1c(Ironmike stated he wanted a dual charger) you will need at the very least 272.16 watts add in 20% for inefficiency and you are over the 300 watt mark @ 326.59 watts.

Trying to charge 2 5400mah 6s lipos on a 300 watt charger is cutting it too close to call safe, running a charger at more than 80% of its capacity is a good way to burn up a charger.

Totally missed he needed a dual!

Well he did post a screenshot of a single and I almost missed that myself.

OP - what do you call affordable? The UP120 is about $130 - is that your max, or can you go over?

I have the 2-channel version of the charger posted up by RCRod - I like it. 2 channels of 20a/300w power.
https://hobbyking.com/en_us/0620duo-600w-charger-300w-x2-version-2.html
I am using a 500w PC power supply for it, but most people will use a 800w-1000w server 12v PSU - available from ebay for around $60, or here - https://www.smc-racing.net/index.php?route=product/product&path=141&product_id=459

Also, when I went to grab the link to my charger, I saw this one. 2 channels, 20a, 400w. I don't know anything about it, but SkyRc is a good brand - they rebrand for a lot of other companies. Note the 400w is shared between the two channels - but 200w per channel will get it done for your 6s packs.

SkyRC is actually the OEM of the iMax B6/B6AC charger. Hence the reason SkyRC are the only ones to come with the little genuine label on the bottom. All other chargers that look like those are either a clone, knockoff or rebrand of the SkyRC chargers. The SkyRC chargers will often times have higher quality everything.

There is a thread over in he Kraton section; I went with this one:

http://hitecrcd.com/products/chargers/dcdc-chargers/x2-700-2-port-acdc-multicharger/product

It requires a separate power supply.

Great points slick2500. I've been using 2S & 3S Lipos mostly, as I only have one 6S Lipo, so I've never tried parallel charging 6S Lipos. If charging two (6S) or four (2S) Lipos that were only 5000mah, you could probably use a 300 watt charger, but would be very close. To help others determine what charger rate they need, this is an excellent RC CHARGER WATTAGE CALCULATOR:

If going the paraboard route make sure the board exceeds your amperage needs, ie do not buy a cheepo off eBay.

And that calculator is pretty cool, never seen that before.

 

[Ironmike340]

Sooty for the confusion. I will be charging only one 6s at a time,but wanted a dual so when I charger a pair of 2s or 3s it will do it. All my batteries even the 2s are around 5000mah. But as far as the 6s only one at a time if I would be better off with a single charger let me know I am not against buying from hobby King and don't mind a unit with power supply built in

 

[Ironmike340]

Also it doesn't need to be the fastest I just want it done safe.

 

[slick2500]

This charger I think would work perfect, https://www.tomtop.com/p-rm7560eu.h...6k6a8R6PHI6frUruryCF9mNDmWU9-newaAo5ZEALw_wcB it's AC powered, it can do 240w if using one channel for charging your 6s pack, then if you wanted to charge either your 2s or 3s 5000mah batteries at the same time it will do 120w per channel. With a couple of balance boards you could charge 2 of the 2s batteries on one channel while charging the two 3s batteries on the other(but only at 0.95 C for the 3s).

Thanks slick2500. It always used to take me a bit to calculate, until I found that charger calculator. I agree, there are so many chargers that are copies, rebrands, etc. My Turnigy charger manual is exactly the same as my Thunder power charger manual. There are definitely some great choices though.

 

[slick2500]

I still believe that their is actually one manufacturer of the actual charger boards, and they are sold off to all these companies and they add in their own caps, connectors, power supplies ect to meet their needs.

These are companies that I know of that use the same style for their chargers.
Hitec
Ultra Power
Thunder
SkyRC
Revolectrix
Turnigy
EV-Peak
Tenergy
Reedy
Onxy
Racers Edge
Hobbyking
Protek
Dynamite
GT Power
Venom
If you look at the chargers they all use the same button layout and screen, most of the time the only difference between one manufacturer and another is the color and/or shape of the case.

If anyone has a single port charger(with sufficient power) & wants to charge at least 2 batteries at once, I have an extra Parallel charge board, that I'm not using. It has the popular EC5 connectors. Parallel charge boards do not come with XT90 connectors, but can include the (2) EC5 to XT90 adapters that are in the picture, which will allow you to charge (2) XT90 batteries (same as Arrma uses) at one time.

Ironmike340, you mean the board & connectors? If yes, keep in mind, it can be a bit tight hooking up some batteries (if you need the adapters for XT90 batteries), if your main leads & balance wires are extremely short. I checked & my batteries were ok, but 1 pair, I did need to turn the board on it's side before placing it all in my Lipo safe bag. If interested, I can check minimum shipping cost?
