Status: offline 		So, this thing arrived today via UPS and man is it the BOMB. It does it all.. charges at speed (up to 3.0C charge rate), auto adjusts the voltage and shutoffs, has a slick LCD screen to show you what is going on with each individual cell, all at an affordable price. You can even plug in a hot battery right after you fly and it's still kosher. Anyone else out there using this thing? What are your thoughts?

The only obstacle I've run into is that 2 out of my 4 batteries apparently are so out of balance it triggers the "Safety Charge" mode... how annoying. Maybe it's because they were just out of balance from the stock E-Flite charger, or maybe they are just bad batts, not sure.

Status: offline 		Do those packs ever come back into balance and if they do, do they end up out way out of balance as soon as you use them?
It sounds as though those packs may be toast
Good luck,
Pete

Adapter,

Status: offline 		Don't forget to order FMA's adapters for the type of battery you need yea! E-flite batteries take the GP adapter. I am a big fan of plug-and-play without having to hack apart stuff and modify stuff and solder stuff... I am here to enjoy the hobby as a pilot, not a mechanic (for now at least!). : ) That's why products like the Cellpro, batteries from MaxAmps with pre-soldered Deans connectors, and the power source below, no tinkering:

I am using a Samlex regulated DC power supply: BAM! Click me.



The CellPro 4S came with both banana plugs and alligator clips to connect to the power source, so that was quite convenient. I will report back after today on how the cells turned out after the CellPro rebalanced/restored them.

Status: online 		I have a couple of these great chargers and the necessary adapters. I was charging a 2100 pack once and noticed that one cell was out of balance. At 90% of charge, the charger beeped once and went into balance mode. After about half an hour the music started signifying end of charge and sure enough, all treee cells were in perfect balance. The only charger I use.

Status: offline 		When I went shopping for a LiPo charger earlier this year, I also settled on the CellPro 4S. It is an excellent charger. The only drawback is that it only charges one battery at a time. The serious electric flyers at our field have 2 or 3 of these, and can fly pretty much continuosly.

Status: offline 		The CellPro 4S was recommended to me and I like it. I still follow the safety rules for charging location, etc., but it seems like a very safe charging device. I would like it to have a "discharge" function to prepare batteries for the "storage mode," but otherwise it's fine (I've been spoiled over the years by having the LITCO Alpha 4 for the nicads!)

I also purchased the 36" extension (handy for charging in the fireplace) and also the the Thunderpower adapter. (In addition I originally bought the "generic" adapter and so far that was an unnecessary purchase ... mistake?)

Status: offline 		When I first got my CellPro 4s, I noticed that all my batteries were noticibly out of balance.
After the first charge, they have remained well balanced ever since.

I liked it so much that I bought a second one that indeed can charge at 3c as well as charge A123 batteries.

Next step will be to try some A123's

The FMA Direct website lists all their adapters and LiPo brands they support. Make sure you look under "more" on each adapter for a full listing of brands.

The Deans connectors do not matter: The batteries are charged via the balancing plugs.

Status: offline 		I have the same observation, at first all my batteries were out of balance because I was using the E-flite stock charger... but now that it has gone through a couple cycles on the CellPro 4S, everything stays in balance very well. Sweet.

cp-cs to cp-gp?

I'm guessing gp is great planes, but I really have no idea on the other ones (cs maybe sommon sense? but if so, what version?). Are you talking about the balance connector?

you may also mean convert =)

I'd be glad to help, just post back what you mean by the acronyms if that's what they are

lol, cp is probably cell pro =P that one went right over my head =P
