chargers

i was at the track today running my rc8. I have 2 5000mah 4s batteries i use. My charger is a Hyperion 6060i AC/DC. When i started to charge one of my batteries it would only charge it at 3amps. i never really thought anything of it. but it should be charging at 5amps cause its a 5000mah battery. I then put my second battery on my buddys ice charger and it charged it at 5amps and was pluged into a powersupply.

i was wondering why does my hyperion charger only charge at 3 amps and my buddys ice charge at 5.

is it cause im pluged into the wall and he is on a power supply.


thanks.

IIRC, the 0606i is a 50W charger. Which means charging 4s will get you a max of ~4A (@3v/cell) and will drop to ~3A at the CC/CV threshold.

so what charger would charge my batteries at the full 5amps besides the ice.(i dont realy like the ice charger)

[BrianG]

There are a bunch really. Just look for anything that will charge at least 4s @ 5A, and has at least an 84W power limit. For current hyperion models, that's EOS 0720i and EOS 0610i DUO2.

Edit: And those take anything from 11v to 28v for the power supply. For a given power, using a 28v supply will require a little less than half the current that a 12v supply would require.

Since the 720i just came out, the 610i chargers are selling cheap... Look around and you may find some deals. The 610i is a 250 watt max charger and will do what you want, but will require a 25amp power supply (min) to push out 250 watts.

we sell the 610i at work so maybe i will look into that.

thanks.

wait we sell the 1210i charger. would that do what i want?

180 watt output, IIRC. I have one, but you do need an external balancer, like the lba10, and if you want to charge 7-12s you have to network 2 lba10 balancers. It is a versatile charger, how much can you get it for?

Or buy another charger cheap such as a 5i and save the money for batteries... much better IMO to have more batteries and slower charging...

I do like to have a bunch of chargers and batteries, currently have 5 hyperion chargers.

I know a guys who is selling a 5i/lba10 combo for a good price... And another guy who has a 5i/lba6 combo too...

[Arct1k]

And that individual just lowered his price ;)

and that sir, is why he is called the pimp.....

If you have the cash, I would go after the duo2

I'm in the market for a new charger myself and would sell my Hyperion 7i, but it errors out near CC/CV threshold at anything over 3.8A when charging lipos.

Aside from >=6s and >=8A and >=120w power limit, the charger I get MUST have the ability to adjust the charge current on-the-fly (while charging). I do some pretty funky stuff sometimes, and do need this. I almost snapped up a 989 but it didn't have this feature.

You mena the guy with the 5i/lba10 stuff, right?

I think the other guy has his stuff sold...

Damn, for the price of the duo you can have 2 of the 610i and enough cheese left over to buy a gangsta power supply...

And I will pimp anyones stuff for them, not just my own. Fees will vary though...

I do think I have ever noticed that feature listed for any of the chargers I have looked at... I do like the 610i, and for the price you can't beat it for features, but i do not think the current can bea altered during the charge.

Any yes Brian, your are funky!

No chargers I've seen advertise this specifically, but it is possible on the EOS 7i. This feature was the only way I could charge lipos the way I need to because of the error. I start at 1C, but then as the voltage gets to ~4.0v/cell, I reduce the current on the fly to keep the voltage there until I get to 3.8A. Otherwise, I'd have to end the charge at the error, and then restart it at 3.8A. I've used it other times as well, but for more obscure reasons.
