Kraton Cheap powerful charger ....

[Revomikey]

Hi guys, firstly, you have helped me so much, I can't thank you enough, but like a vampire I need more, more, more...

I have a charging station consisting of 3 IMAX b6s and a monster PSU capable of huge amps.

As I was buying 6s for the Kraton I opted for 6s packs instead of 2x3s.

The thing is my current chargers will only reach 2.2 amp, the packs are turnigy 40c 5000mah. At 2.2amp I'm barely hitting half a C.

I know slow charging won't hurt but 2.5 hour charge time is too slow for me.

I don't want to spend a fortune but I need something with more guys.

Any cheap recommendations to help me hit at least 1c?

Thanks dudes

I use an HTRC C240, works great, ~60 bucks. 150W on AC and 240W on DC.

Check out the HTRC H150 duo 2x150w ac. It can simultaneously charge your lipo's at 1c, even more.
I have 2 of these so 4x6s lipo are fully charged within 1 hour. Never had any issues.

If you have a PSU, there are several 250w-300w DC chargers for about $50.
Is your PSU 12v or 24v? And what wattage?

 

[Jerry-rigged]

Of your PSU is 12v, I would look to the hobbyking Reaktor charger line. They have this 250w, 10a for about $55-

My charger is the 2 channel , 300w 20a version-

If you have a 24v PSU, then I'd look to the ISDT Q6, 300w, 14a for $50-

I have that charger as well in my car. It's an OK charger, but there are quite a few that have issues. Mine, on one channel, I can't decrease as the increase button doesn't work. I fiddled with it for an hour and somehow, it reset and works again. Not sure I'd want to rely on it as my only charger.

I have the hitec D7 in the house, it will do 2x200/2x20A on AC or DC. It's pretty pricey to buy, I won it used on ebay for $135.

In other charger threads, this one came up:

Since you have a good PSU, might want to just get one of those. Might want to read the manual though and make sure it puts out enough watts/amps for your needs on the voltage your PSU supplies. For $110, it would have been perfect in my car on 12VDC for what I do.

@Revomikey what would your budget be for the new charger?

Have you taken a look at the Recommend me a battery charger thread already? If not, I highly recommend it!

 

[Revomikey]

Thanks guys, I will check those chargers out, my budget is next to skint as I have spent nearly 600 in the last two weeks on my RC. The h150 charger looks fine, great price for a dual charger, not knowing the maths will it charge two 5000 6s packs at 5amp (1c)?

 

[CrashBoom]

P = watts
I = current
V = voltage

P = IV

We know voltage and current. A 6S battery charges at around 25.2V and you want to charge @ 5A.

So, you need about 126W to charge one 6S battery @ 5A.

Another note, if you use a DC power supply, you need to take into account the conversion efficiency when sizing it.

Most AC/DC chargers are capable of charging at higher rates on DC vs AC.

 

[JvG]

To be short, yes it will, on AC

 

[Revomikey]

Will my decision has to be sped up due to 2 of my imaxs going up in smoke, perhaps I overloaded them trying to charge the 6s packs yesterday. Thankfully my old accucel is working so my son can use his rock crawler in the snow.

I will order the HTR H150 Duo, looks like the best bang for the buck.

thanks fellas

 

[Revomikey]

Slightly different model but same specs. Hopefully it will arrive quickly.

Not the same specs I don't think.

The H150AC/DC Duo is 15A x 2/150W x 2 on AC or DC.
The C240 DUO is 10A x 2/75W x 2 (shows ch1+ch2=150W, so assuming that's a combined) on AC, not sure Amps on DC, but shows 120w x 2 on DC.

[CrashBoom]

I have the C240. For output > 150W you do need to use a DC PSU.

You can charge 1x 6S @ ~5A on AC. Per channel max is 150W on AC or DC.

 

[Revomikey]

Oops, think I balls up. So will I be able to charge 2 6s at a time on DC?

 

[CrashBoom]

You can charge 2 6S on AC, but you'll be limited to about 3A on each. If you use a DC PSU you could do about 5A on each.

 

[Revomikey]

That's a relief thanks. I made a huge cock up, I got the htrc modems totally mixed up. Seeing as my weekend runs will involve 4 lipos, 2x 5000 2s and 2 X 5000 6s perhaps I should mix them up to charge, 1x2s and 1x6s to keep the wattage down a bit

 

[CrashBoom]

You just have to keep the total wattage < 150W on AC.

You can use the formula above to determine what combinations are possible to maximize wattage. Voltage for a 2S battery would be 8.4V.

For another 50 bucks you could triple the power. Just sayin'. Nothing like turning around 6 batteries in 30 minutes.

qty 2 hp server power supplies, $40 on ebay
isdt T6 charger, $75

That'll get you 600 watts, and the power supplies are good for plenty more if you ever wanted to add another T6 or maybe a different isdt charger.

Do you have any links by chance?
