So I am looking to get a 10awg charge lead with low IR. I tried to do some 40amp charging/discharging last night with my 12awg leads and the wires got up to around 115 deg. My iron wont do a 10awg connection well, so I am just looking to pre purchase one. I would prefer one that is configured for 2s, because I never change anything else.


Also, just a question about how to do it better. I had a 2mm bullet that needed replacement on my current charge leads. So I used flux to prep the wire and the new 2mm bullet. I tinned both with 60/40 solder, heated both at the same time with my iron to get a good flow. But afterwards, I noticed that my IR on my packs doubled. I assume this number is because my solder job/bullet are trash. Obviously, my packs didnt really double in IR. Every time i have used a factory built lead, the IR calculation yields more consistent and probably more accurate numbers. Could it be the lead free solder they use? I kinda wonder if my solder is not as good as it should be or if its just my technique.

Check with the guy who imports elan gears chargers to the US (Porterhouse motorsports?) he might be able to set you up.

FYI, while the 308D would not charge an iPhone 5s out of the back USB port, the 406 will.

Just picked up a 406 and im searching out a power supply. I only charge 2s packs at 10amps max. Could this power supply provide enough power to charge 2ea. 2s lipos at 10amps on each channel? The amps look high enough and 900 watts should be good,correct?

With this power supply, you can charge 2S lipos to the maximun power of the 406 each channel together.
900W/2 = 450 W for each channel power.
450W/8,40 volt (2S lipo's) = 53A.
Limit of the 408=40A each channel.

Yeah thats way bigger than what you need for 10amps on each channel.

It likely will be slightly lower, not much though. Remember the 60 amp input limit, and the charger consumes some of the power (efficiency).

But yeah, it will easily handle elex's stated needs, even the 20 amps per side I think he's saying (2ea. 2s lipos at 10amps on each channel).

Thanks guys. I should have worded that differently. I charge 1 2s on each side at 10amps each.

that PS is way way way over kill, lol. But yeah, it will work fine. And if you decide to charge both packs at 20amps, your still good. I charge 2 2s packs at 10amps and use a cheapy protek 20amp psu. Keep in mind, its all about the watts, not the amps. Charging both of my 2s packs at 10amps, only pulls 15 amps of current from the PSU.


10x8.4(full voltage) = 84watts.

84 watts x 2 = 168 watts of power needed. Add about 20% overhead for giggles and anything 200 watts and higher will work

Lol that PSU will be super overkill for 10a per side. Also why waste your money on this charger if you're only gonna do 10a? There are lots of chargers you could have found to do 10a charging for lots less money.

You've got the hardware. Push it! 40a baby

Just got this charger. Very nice

does anyone know the max wattage this charger can do per channel at 12v input?

JiuHaWong

How many amps can the PS do?

Watts = Volts x Amps

edit: Didn't you just sell your icharger?

yeah....dont ask man...I change my mind like the wind.


my PSU is 75amp 12v and 117v ac. But.....I just realized my charger can only do a 15amp 4s charge at 12v. Or about 252 watts, lol. In order to get the full 500 rated watts....you need 24v. I would like to stick with 12v. I see the power labs will do 404 watts at 12v. I am curious what this one does. I could not find the specs in the online manual.
