New PL8 owner... and I don't know what to do!
Christmas came early to my house this year and my wife gave me a PowerLab 8 v2!!
So, now that I have the charger I am completely lost as to what I need. I have two Dell 6650's and the charger. I think I can handle getting the power supplies wired in series and power the charger... where I am lost is: what the heck do I need to parallel charge my 6s packs? I use EC5 with jst-xh. Can I use an EC5 squid along with a JST-xh squid? Or do I need a paraboard? I will not be charging more than 6 packs at a time for quite a while. Do I have to get revolectrix specific paraboard or squids? I am confused and don't want to do anything wrong! Thanks in advance!!

I will take some pictures of what I did and post tomorrow for you (squids/JST XH), I have the exact same set-up. If you have any questions at all about the 6650s PM me.

The bare wire MPA will take care of parallel charging without any addtional boards or adapters. All you need is the Powerlab interconnect cable that goes between the MPA and the charger.
Squids can work and provide more flexibility for packs with very short balance leads. Squids commonly come with a JST-XH connector to plug into the charger. What I have done is swap out the JST-XH for an FMA pigtail. If prefer something more plug and play I would use the SPA You can plug the squid directly into the SPA as well as use the SPA seperately to charge any single pack up to 8s. The major concern about squids is the lack of fuses. Many are quick to dismiss the safety concerns. However there's no disputing this documented list of incidents. Also be sure to set the wiring mode to JST-XH and set the input current limit to match your supply.

I'm pretty sure I have a link to your thread about the 6650's saved as a shortcut on my phone lol. The pictures look good enough that I HOPE I don't have to bother anyone about the wiring part, but if I do I'll take you up on your offer. Looking forward to pics... I gotta see something to learn most of the time. Can't wait to get this thing up and running!

Mine came with a little board to go between the FMA charger connector to JST-XH squid... so I cut off the end of both and re-soldered so my JST-XH squid now can plus straight into the charger. Under the green tape is my solder. See here? A little small..

If you are mindful and things, you can safely charge with squids. I've done it 1000+ cycles in 2 years now. Don't break in packs in parallel. Know the pack voltages. Plug them in carefully. And as a failsafe safety measure charge on a fireproof surface and not in a truck like I show in that photo.

That brings up a good point, Slyster. With a squid and packs that are close in voltage, will they "even" each other out through the leads?

The MPA uses self resetting poly fuses with a heat sensitive coating that changes color when tripped. Some have added these themselves but without the color change. I don't have a link. Adding automotive fuses would be kind of bulky and awkward as you need 7 for each 6s branch. On a typical 6s squid that would 42 fuses. For main charge leads its easier. Two per branch, 40 amps each.

Okay, here's what I did to keep my squids compatible with my Icharger 306B.

I wish revolectrix would come out with an mpa board with EC5's mounted directly to the board like they did with the deans one. I would buy the bare wire one but I hate soldering and don't want to do solder six EC5's on.

That sounds great, but to my knowledge there is no such thing as a PCB mountable EC5 connector. If you know of one, send me a link. But thanks for the feedback anyway!

Could you mount them the same way these are mounted? http://epbuddy.com/index.php?main_pa...roducts_id=343

Well I got the power supplies all wired up and working!! Can't believe it. Never would have happened with out the help from you guys!!
Now... when I plugged the charger in, it came on. I tried to charge a 6s pack and it said Bad Cell Count Node Wiring FMA. What the heck does that mean? I know I could search, but I'm tired guys... Do I need a specific type of connector to the charger? I just used my EC5 to banana... plugged the banana connectors right into the charger... wrong?

Thanks a bunch... I've been sitting at the table soldering and just noticed the fma plug was 9 pin. Then I come back to the computer to find your link! Perfect. Thanks so much...I'll be trying again shortly!
