No, that's terrible! The 3010B is over kill though. If your batt has a 5C charge rate, you could charge it in about 10 mins at a fraction of the chargers capability, balancing at the same time.

Do you think I'm doing something wrong or is this just the limit of a triton 2 eq?

I've never had one, but I looked it up. It looks like it's designed for a 1C charge rate on lipo's which is approx an hour. But from 50% it should charge your batt in 45 mins or even faster. I'd say either your doing something wrong, or the charger is malfunctioning, or the batt is not in good shape. Sometimes if the batt has been over discharged, the cells take a long time to balance, especially when the charger is trying to peak charge them to 100%. If your not draining it very far in flight, try charging to 90 or 95%, see if that speeds it up.

It's a little cheaper to buy 2 55A 13.6V power supplies than to buy one 40A 27.2V power supply. And you will get a lot more power out of them for these big chargers when linked in series. Another benefit is they will take a 2000i to it's max of approx 1600W, the 40A 27.2V will not. Which makes more sense to you?
I called Iota Engineering today, and they told me that the largest power supply I could run with my 2000W Honda generator was the DLS-27-25 which is the 24V 25A power supply. I guess this power supply, even though it only puts out 675W draws closer to 1100W. Does this make sense to you? He said I could run 2x 25A 12V power supplies, but it would just add to the cost and complexity. He told me there was no way I could run the 24V 40A power supply, nor could I run 2x 12V 55A power supplies with my 2000W Honda generator.

I have personally ran 2 55A 13.6V power supplies off of my 2000i honda charging 8 5000 6S batts at 5A each. AND the PS's were not in series which is less efficient than linking them in parallel. The chargers I had at that time were 4 Hyp. 615i Duo Net 3's running all at the same time at 5A 6S per side(1000W into the batts)! So, the 2000i is capable of more than he thinks ie. 1600W CONTINUOUS 2000W SURGE Remember A X V = W and you have to subtract some for the losses in the electronic equipment. I should have my second 3010B tomorrow, so my next experiment is to see what the max amps I can charge off one 2000i gen charging 2 5000 6S batts(one one each charger)to 95% with my 2 55A PS's linked in series. I'm hoping to get at least 4C and possibly 5C. We'll see.

Thanks for the reassurance, and I'll be looking forward to your results. How hot do these Iota 55A 12V units get? How much cooling do they need to be happy?

I'll post as soon as I know. I've never seen one hot. They barely get warm. I've always kept them clear so air can move around and through them.

I got a new set of charging system.
Hopefully, it lasts long!

Of course you can run that power supply off a Honda 2000 generator but you may have to limit your output slightly to not overload the generator. Same applies to the pair of 12V units.

@shine153,

Can you post of pic of how you are attaching the leads of the power supply to the leads of the new iCharger?

Did two 40a fuses come in the power supply or did you install them?

Are you using 12 or 10ga wire to the charger?

Turns out the prob I encountered turned out to be a bug in the 313f software. Downloaded 313g and seems to be working ok now.

30amp charge, normal balance
29.6A out of PS
11.19A out of wall socket

These were @ 25V

20 min, 3sec

6845mah in

Inline Medusa watt meter said charger pulled 6439mah. This charger seems pretty efficient.

@whytlotus,
That's a good question.
I'm using 12 AWG for now.
The wires from iCharger 3010B to power supply are 12 AWG.
The wires from iCharger 3010B to battery are 14 AWG.
Usually, for a 20 amp circuit, use 12 gauge wire.
But as you may know, 3010B handles up to 30 amp.
So, 10 AWG would be better option, but you know...

Quick table for normal use:
Gauge (Amps)
14 (15)
12 (20)
10 (30)
8 (40)
6 (65)

Does wire length also play a part in what gauge wire to use?

@ shine....
I was going to use 10 on mine. I found some 8 ga which is probably overkill. But it was only .20 per ft more and a bargain @ .99 ft, so why not. If it don't fit the connector I'll use 10 ga. The female bullet connector you're using is 4mm?

In addition to AWG size, wire length and wire material(copper or aluminum) play some role here.
Aluminum has more resistance than copper, of course.
Longer wire means larger resistance.
For example, 12 AWG = 1.588 Ohms per 1000 ft.
My 12 AWG wires are about 1 ft now, so it has 0.001588 Ohms.
Voltage drop would be 0.098@24V.

If you need more info, then please refer to the link below.
