CellPro Power Lab 8 1000W Charger

[Gunnarjohn]

Will I be abel to charge 4 6s 3300mah Voltz batterys at 2c (26.4A) in parallel with this. Thinking about buying this and a paraboard from epbuddy. What about 3c (39.6A)?

[TJinGuy]

Paraboard does NOT work on FMA chargers.

Hi:

The following link takes you to a spreadsheet that FMA developed to answer questions about power capabilities and requirements.

http://www.revolectrix.com/support_docs/item_1301.zip

Using question 5 from the ss, yes, you can achieve 26.4A charge rate in to 4 x 3300 mAh packs charging in parallel. You will require a power supply which can deliver a minimum of 18v and 44A up to 24V and 33A. Currently, the PL8 will not go above 30A on the output current.

Hmmm, very interesting wording.

[terrabit]

I was thinking the same thing. It would be nice to pull all 1000 watts for 6s. That would require a charge rate in the vicinity of 40 amps.

The new V2 firmware upgrades the Powerlab8 to max 60A input, 40A/1344W output. So with the right power supply you can now charge 6S packs at 40A (approx 1000W). To do so you will need something like a 24V/50A power supply.

The way the electrics have taken off is unbelieveable. Just a little more than a year ago, my hyperion 0615 duo was considered to be one of the big dog chargers, now it's not even a pup.

With lipos and chargers getting better and cheaper, I can only wonder what the electric technology will be like in 5 years.

I have downloaded the v2 software into both of my PL8's. So far so good. The banana plugs start to get a bit warm at max output. But that's just an observation.

Terrabit (and anyone else that has upgraded to V2),

I don't recommend charging at 40A with the old banana plugs/wires. Read this post for further...

FMA is looking into the issue and will most likely be offering 10 or 12g wire with 40 or 45A fuses.

Check the thread on RCG for further.

Thanks Dave! I figured as much. I don't use the fused leads. I keep a Fluke meter nearby and check it frequently. My temps have never gone much over 100F.

Would it be better to go with a 12v/75amp ps or a 24v/40amp ps? Both do right at 1000 watts output.

Looking at getting a biggish PS for the PL8. One of the Iota's most likely. Unsure of what the advantage would be for 24v vs 12 v PS

[kgfly]

All chargers are limited by input current as well as output current and output power. The PL8 will not deliver more than 600W (out of a total possible 1300W) from a 12V supply.

12V/75A => Max 12 x 60 = 720W input = 600W output
24V/40A => Max 24 x 40 = 960W input = 800W output

The charger will be more efficient and run cooler at higher input voltage/lower input current. So of the two, the 24V/40A is definitely the better choice.

If you want the potential to use the full 1300W output power you will need a 24V/60A supply.

[mahbouni]

If all your chargers support 24-30V then get a 24-30V PSU. I got a 15V 60A PSU because in addition to a PL8 I have a CellPro 10S and two CellPro 4S chargers which can take up to only 16V.

[kgfly]

Good point about considering what other chargers you want to run from the same supply. Or get the 24V supply and upgrade the other chargers

[John Cook]

would this be a good charger for charging 6S packs that are run in a 2x 6s series setup, but charged in parallel? Otherwise I could buy 2 of the iChargers, but this seems more convenient and I love my cellpro 10s.

I have 2 x 600W PSU's that are 27V I was going to run in parallel for powering the charger

[kgfly]

Yes it would be a good solution.

You can charge as many 6s packs in parallel as you want. I frequently charge 6x 6s and 4x 6s in parallel. With a PL8 and your two 600W 27V powersupplies in parallel you could pull the full 1000W at 40A on 6s.Watch the banana connectors though. At 40A, they are melting on some people.

This would handle pretty much anything you care to throw at it.

I normally charge at this rate..

But tried a max power charge...was fully recharged in just under 8 minutes.

Here is how I set it up..

[John Cook]

good grief you guys are taxing some power there haha!

Another question.

I really like the ability of my Cellpro 10S to read individual cell IR's.
When you charge in parallel does the charger just see "one pack" so effectively I'd lose the ability to see each cell IR??? That's my guess anyway.

Also, on the balance adapters that allow parallel charging, if I happened to only want to charge one pack NOT in parallel. Can I still use that same parallel capable adapter, or do I need a whole different balance adapter?

Just want to make sure w/e I buy is what I will need.
thx

I posted the first 2 videos for the PL8, Installing the CCS & Running the CCS, They can be found here: http://www.revolectrix.com/pl8_video_tab.htm Please let me know if you have any questions, thanks.
