Help with cellpro 10s please. Charging 2 x 3s lipos

[Three6ty]

Hi,
I just bought a cellpro 10s off here. All good and I know my way round it as I already own a 4s.
My question is, as I understand it, I can charge 2 x 3s packs together providing they are pretty close state of charge etc. What balance board, boards or leads do I need to do this. All my batteries have standard jst-xh balance connectors on. I do have one board with the charger already but it says it's for charging one battery at a time only on it. It's this one
Thanks for any help.

You need two boards.

The battery board you have linked to is one for a Thunder Power balance connector.

Ill look for the one you need in a bit.

10S Cellpro Adapter (Esky Align GPKO) - Batteries Accessories

As above, and cheaper.

That's the one I got with the charger. I did realise it was of no use to me

Yep. That's the ones I need. Going to need 2 of them. I had already found them but was confused by the fact that they have 2 leads coming out of the board. I guess I only need to use one of the leads corresponding to the side of the board I need to use with the correct plug on that side if that makes sense.

Just one other question. The charger will charge the lipos to storage state. Will it discharge to storage state if using the balance connector and the main discharge leads? A feature I find very handy on my overlander charger.

It doesnt discharge unfortuantely.

They have 2 leads for when you charge a 6-10 cell lipo, both leads plug in (to charge 1 lipo) and just 1 lead per board if charging 2 lipo's of 5s or lower.

You can connect yout two 3s packs and charge them evewn if they are not the same charge state, however it will throttle the charging so that they both end up fully charged at the same time so the nearly full one won't be finished first.

Lack of discharge function is an issue - the revolectrix packs don't mind being left fully charged but I had some loong max that are ruined after a year of being left fully charged despite only 10 cycles or so.
So I might be looking for another cheap charger that will discharge up to 5S lipos when I buy some more packs.

Although the charger is split into two 5S channels and you use the plug blocker to join them, if you are charging small lipos via the balance conectors only it can charge 3 3s packs at the same time if you make up the right lead.

IT will consider the 3x3s packs to be one 9s pack that is a bit out of balance.
It still monitors each cell separately and will slow down if one gets fully charged.

Does anyone here know where I can get a lead to do 3 lipos or is there anyone here who could make such a lead?

Yeah, the lack of discharge function is a disappointment to me. I should have read up on it more closely. Expected a charger like this to carry that function. I always like to put my lipos in storage state. I'm convinced it helps there life. Obviously this charger will put them to storage from used but inevitably some lipos come home in a fully charged state.
I have a overlander charger which does 6s and will discharge lipos down to storage state. It's also multi chemistry and will cycle nimh's, pb, nicad etc. It was only about £35. Plus it comes with a shed load of leads to cover loads of connections.
I have a 4s and I think that is a great charger and I'm sure I'll love the 10s especially having the convenience of charging 2 or 3 lipos at once.

Rich,

Here is a picture of my PL8 using Parrallel Charging leads to charge multiple batterys in one go. The priciples remain the same for the Cellpro 10 - I used to use this cable setup on mine. You can get the cables at Fastlands now i believe, but failing that, i got mine from a place in the states.. Only took 5 days to arrive, and no customs charges.

Have a read of this also, its a run down on how i do my parallel charging

Gone down this route now. Ordered parallel charge leads/balance board and a big power supply. So will be able to charge 6 lipos at once.
Ive done a bit of reading about and all seems simple to do, but is there anything you guys know that I should be aware of when charging all these lipos in one go other than the obvious safety stuff?

[Aidi]

When you plug them up, you will effectively be charging one big 6S pack.. Its the Amps which you need to be accurate with.

So, if for example i was charging 4x 6S 5000mAH Lipos, if i wanted to charge at 1C i would set my charger to pump out 20amps. 1C for one battery would be 5amps, so 1C for 4 batterys would be 20amps.

Personally, i put a max of 4x 6S 5000mah batterys on and charge at 10amps (1/2C) Takes about 1hour 45 to complete with batterys at around 20-25% discharged.

It will all depend on the PSU you have and how many amps it will pump out and how quick you need to charge. I only charge at 1/2C becasue i have them on the table next to me whilst watching TV with the PL8 hooked up to the PC so i can see what it is doing.

Although its safe, take the necessary precautions assocaited Lipo charging.

Do the lipos balance as well as if you were putting one lipo on to charge individually?

[Aidi]

Yep.. It will balance correctly
