Cellpro 10S Charger

I'm confused...10S means ten cells right? Why can't he use the same harness for wiring them as one 9S pack to charge them with?

I think the answer is because you won't be able to plug into the balancing ports or available cards and this charger from what I can tell won't charge unless the balancing plugs are connected.

I have a question. I'm considering a 10S for future helis I dont own yet, but will likely want to charge 3S, 4S, 5S, 6S and 8S batteries on it. Some with ALign balance connectors and some with TP type balance connectors. Can somebody list the minimal set of balance adapters that need purchased to handle both balance taps across that different S sizes? It wasnt clear to me what to get from the fmadirect site.

THanks,

There are only two balancing connectors available which cover any type of battery with balance connectors. If you order two of each you will be able to charge two tp batteries or two e-flight batteries, and also if you go to a ten cell battery you will need two of the same balancing cards to cover all ten cells. So again get two of each which I know adds $60 to the cost but is well worth it considering the flexability it gives you.

I have a question, I run a 450 size heli, that runs on a single 3S1P pack, right now I have 2 of the same brand same model Lipos, but will have ones of greatest capacity and brand soon.

With the 10S can I charge two of my 3S packs at the same time, even if one is discharged further then the other, or is it really designed for 500 class helis and such, that run on 3S2P batteries, where the two packs would be discharged at the same level.

If you read the instructions on them, it explains that it performs best with two identical batteries discharged to the same level. When two batteries discharged at different levels are connected it will charge both batteries at the "C" rating you choose until one battery reaches full charge at which time it reduces it's charge current to one amp, which would be less than 1/2 C on a 2200 mAh battery. Therefore it suggests to watch it and remove the first battery when it's charged and finish the second on its own or charge them separately from the beginning. This is a great charger and works well with batteries as long as they are close to the same discharge amount. Therefore if you're flying your 450 with the same batteries and for the same approximate time they will charge together well, I have done this. The charger with all accessories including the power supply is a bit on the expensive side but well worth every penny. I have no vested interest in selling this as I am just a heli enthusiest like most others on this forum.

I have found that I can use the software without an internet connection. Not sure what could cause your issue.

Hi,

You can charge one pack from 6S to 10S or two packs of up to 5S on each channel, they do not have to be the same cell count or capacity. He was inquiring about charging 3 3S packs.

If you're charging two packs, and one finishes before the other, can you unplug the finished battery?

I'm pretty sure you have to turn off the charging cycle and restart it with the uncharged cells.

Hi,

Yes but you have to stop the charge first. Then move the un-finished pack to channel 1 (if it is not there already), and then start the charge again. The down side when doing this is that the charge data is lost once you stop the charge. It is just a quicker way to charge 2 packs of different cell count and capacity

Thanks Howard for clarifying this. I wonder why the charger has to drop down to 1 amp charge after the first battery is charged. I suspect it is due to some safety that must be built into the charger, but wonder if you could elaborate a bit on this.

I've also noticed when charging through the data port on the computer and charging two packs it only shows the data for pack one. All the data for "fuel" and "cap" only show on channel one. Thanks

I have learned to look past the pretty disappointing limitations to the 10S, and I will still buy one over two much cheaper (with discounts) 4S CellPro's

But I do hope the next attempt at a dual output Cellpro will be better, "individual channel control, and 12S" hint hint

Ooops, I did not want to post my message here.

Hi,

The 1 amp is the bypass current. Although the charger has two channels, and can charge different cell count and capacity packs, it has one charge circuit. This is the reason when you have a pack that finishes first for the 1 amp bypass.

Make sure you select either 1 pack or 2-pack charge. When you select 1 pack charge with 2 packs connected, it will combine all the information and balance as 1 pack. It will be quicker if you select 2-pack charge when you are charging 2 packs.

Howard,
I have been experiencing intermittent charge disruptions with my Cellpro 10S. An error message I typically see is "No Plug Blocker" even though the plug blocker IS installed. The error, when it occurs, is always towards the end of the charge cycle. I know I have already discussed this with you, but never got a good answer. I was told to check the resistance of the plug blocker, which I did. It measured 4.7K ohms, as it should.

I also have seen an error message of "Supply Unstable." I am using a Radio Shack 15A switching power supply, typically pulling around 12-13A at peak charge with my settings.

Lastly, I get random occurances of the charger simply shutting off during a charge, Display goes blank, even though the power supply is still turned on. Cycling the power resets the charger.

Could these error messages and random shut-downs be caused by pulling too much current from my power supply? Is there a safe maximum percentage of rated output to pull from a power supply?

I have tried it both ways as 1 pack and 2 pack charge. At times I have seen data for both packs but most of the time It reports as one pack. I will add that even though this charger may have some small glitches, I love it and recommend it to my fellow heli fliers.

You can add me to the list of people wanting a 12S charger. Actually what I think might be best is a cheap 6S version of the classic 4S CellPro.

Hi,

Please check the charge control software under presets, make sure the box is not checked for 1 pack charge. If it is, it will combine the cell voltages to one pack.
