Hi,

Make sure you are connecting both pigtails from the adapter into the charger. The RJ1 pigtail connects to channel 1 and the RJ2 pigtail connects to channel 2.

Thanks Tim and Howard. That was exactly what my problem was.

Have been using my 10XP for about a week now and have run into a strange problem with 'storage' charging. Typically, after the last flight(s), I put packs on storage charge so I don't have to do that at home.

Today, I tried to do a storage charge on a 10S (2 5S packs in series) after a flight. the charger did not stop at 3.85V per cell, in fact, it kept charging until I stopped it at about 4V per cell.

After I got home, I started playing with the storage function and it appears 'broken' to me. I took the same pack that was now at around 4V per cell and put it on a storage charge and it began discharging at 1A. This is a 5000mah pack so discharging was really slow. After about 15 minutes, I took it off the charger and manually discharged it down to 3.9V and put it back on the 10XP. The XP started discharging again and I let it go down to approx 3.82V, then took it off again. Manually discharged it down to
3.8v, back on the 10XP. The 10XP discharged down to 3.79V then switched to charging again. The charge rate showed a gradual increase from .8A to .98A, 180mah put back into the battery, but the voltage was not climbing.

Isn't 3.85V the target for storage? This 10XP doesn't seem to be using that value or, it is just confused, switching from discharge to charge, reporting mah input but voltage not climbing.

Attached are 3 pictures of the CCS screen. First, the presets I am using. Second, screen shot during discharge just prior to switching to charge. Third, screen shot just after switching to charge.

Am I doing something wrong? Presets not correct? Or do we have a bug here?

thanks
Don

Just to let you know this is being looked in to.
Mine Dsc. to Storeage to 3.77 (28%) and charges to Storage to 3.795 (41%)

Also, first week to be using my 10XP (big leap from my old 4S) and also noticed the same during Bal to Storage. It discharges a pack to storage between 20% to 30%. I thought it is supposed to be 50% but did not bother until I see this postings lately. Hope to hear any news/update soon.

Simple fact is that 3.7 to 4.0 is an OK Storage range. I started advocating 3.85 years ago due to the simple fact that it is the mid point of this range.

Up to around three years ago most new LiPolys were shipped with cells close to 3.7 and now most are closer to 3.85. Bottom line is some worry to much about an exact storage voltage.

I agree. ...

Edit: Yes, I see your point.

BTW, how does the 10XP know whenever there is a new firmware update without coming to this newgroup or checking FMA's website? Will the CCS check for updates everytime you start it?

Thanks,

In short, yes. The long answer is that just after you start the CCS is looks for updates. Then the next time you start the CCS it will prompt you to perform the update. In the past you'd have to wait for the CCS to check for updates before you could start using it, so the current order is much preferred.

10xp

I understand that you can charge two batteries at one time. The question is do the two batteries have to be identical?

Several ways to charge two at the same time but if you are refering to one on each of the two Channels then no they do not have to be the same cell count or capacity but...

The CP1010 and CP10XP wa really desingend for charging LiPolys used in series or parallel of the same capacity and discharged to the same level.

If they are of different capacity or discharge levels then when the first one enters the CV stage the charge is also reduced to the second one and it can take a very long time for the charge to end. You can however Stop the charge ,remove the finished one and finish charging the second one after making the necessary plug swaps.

Snip from post @1

Because it is a Cellpro, it is designed to be safe first and foremost. It is virtually impossible to damage batteries with the Cellpro 10XP charger. It will not let you make a mistake. It must see all the cells in a Lithium pack and the sum of the cell voltages must equal the total pack voltage. It is ideal for charging one or two LiPo, LiIon, or A123 type batteries. When two packs are connected to the 10XP, it automatically interconnects them in series internally inside of the charger. It essentially "sees" all the individual cells as one pack of cells. It can handle 1s-5s on either or both balance charge ports, or it can handle up to a 10s battery pack using both ports. To achieve the full 15A max output current, connect both the balance connectors and the main leads from the pack(s) to the banana jacks.* While the Cellpro 10XP can handle charging two packs of different capacities or charge states, it is mainly intended to support 2 pack charging when the packs are the same or similar capacity and state of charge, such as 2 x 4s packs which are wired together in series or parallel during operation in an electric aircraft.

Okay, so I got a brand new CP 10XP and charge a pair of 5s 5A packs in series, using 1 set of discharge wires and the 2 node balance plugs.

Charges this pack fine, taking only 40 minutes @ 2c. Great.

Next pack I get the warning "Ch1 Bad S. count" and "WIRING NODE FMA"

Tried different packs and swapped out node adapters, all of which work - and have been working for quite a while - on my CP 10S.

Any guesses??

Hi,

Check all your banana jack cables for good solder joints. I had a customer this week with the exact same problem and it turned out to be the cable. Let me know how you make out.

Okay, that is something I didn't try, to switch out the main discharge cable. However, I am using APP connectors and am guessing that one of the crimps might have flexed enough to cause an open circuit. I will check as soon as I get home from work and will find out quickly.

Thanks for the suggestion!
