You should be able to do that. Remember that the 1500W or so that you are drawing from your 12V outlet is about 1500/120=12.5A. Most household circuits are rated for 15A and may have several outlets/lights on them.

I'll be running this off a 2000 watt Honda generator.
So to do this is it alright to use 2 sets of your PS that are put in series and then put the two outputs in parallel?

I think so. Make sure your 120V circuit can handle it. It may be different than the 240V circuit.

Have you tried putting 2 in parallel?
I know that you cant put 2 switching bec in parallel,because if they see each other they will not work and eventually burn up.
Do you think that I should put isolation diodes on the + line out from each PS?

No I have not but these are designed to work in parallel in a file server so they should work OK. I think others have.

I used the automotive connectors to wire up my power supplies but they would not hold well. Tried different brands. After much frustration, I used my hot glue gun to 'flood' the terminals with the connectors in place. No more problem!

You can also just squeeze them with pliers. The contact is made by the edge of the bent over bit and you can squeeze the gap narrower so they grip tightly.

Tried squeezing them with pliers. No good. I have 10 guage wires to the connectors so there is a pretty good load on them. If you're using small wires, they would probably be OK.

I can charge them a 30 amps max, I'd like to charge them at 40 amps which is 2c.
To get the full 1344 watts (40 amps) I'd need 1344 watts plus 20%.

Thanks, Angelo

The Powerlab8 wattage rating of 1344 is based on 8s. For a 6s pack the max wattage is 1008 at 40 amps. Add in charger efficiency of 90% and you need 1120 watts to max out the PL8 charing 6s@40 amps. The 47a supplies are good for 575 watts, each and I know if one person that has successully pushed it past that (but for how long,?????). So two 47a supplies will give you 1150 watts. Also remember that the wattage peaks occur near the end of the charge and don't last all that long. The charge will start at about 90% of peak wattage and granually increase as the cells reach 4.2v.

I've sold several pairs to those with Power Labs and so far I have not heard of any problems.

is the 24v PSU still available?
how long will it take to ship to California?

Yes. I have plenty of stock. I ship USPS priority so a couple of days.

Hi mate,

I've just sent you an email (as suggested on your website) to request a quote for a power supply to be shipped to Australia.

It is for a iCharger 3010b and I'm new to the whole charger / PS business.

Thanks in advance.

Rgds.

I talked to two guys at a fun fly today who had figured out how to have two 12V supplies in series with both of them grounded, and able to touch each other. There's some trick with keeping the A/C side grounded while ungrounding the D/C from the cases. Is anyone familiar with this technique, or have a diagram of how/why it works?

There's a whole thread on it . Look here

Also some more info in the 12V 100A supply thread in the most recent posts.
