charging 10s2p

[urbs00007]

i will be running my cat with 4 5s 5000mah 70c battery packs. in series and parallel to get 10s 10,000mah. would it be possible to wire in a charge jack to charge all packs in the boat at once. my charger is a cellpro powerlablab 6. instructions say i can charge as many same cell batteries as i want. could it work? might be alot easier than pulling out 4 packs and hooking them up to charging jacks. I imagine it would take awhile to charge, but i have numerous boats to run while waiting.

Anything is possible..
1)Whats the wattage of your charger?
2)Can your power supply handle your charger?
3) If something goes wrong...poof goes the boat/ESC and batteries = $$$$$$$

Charging batts in a boat is never really recommended.

I tend to stay away from charging more than one pack per charge port. I know there are balance boards but they eliminate the chargers built in safety measures. If one cell of the four given #1 cells should have low resistance it could overcharge and blow. This is my take on it anyway.

I would do the 4 in parallel on setting 3 at 10 amps per. I do this with no issues on pl6 and pl8.

how long does charging (4)5000mah 5-s usually take. I would use a 12 volt deep cycle marine battery. 2 sets of batteries, pull one set out, replace with fully charged set. could you guess my run time with revo go packs silver 420's? thanks

I would strongly advise against this. You would have to charge all cells in parallel and connect all balance plugs in parallel as well. The risk increases with the more cells in parallel due to imbalance between cells in the same position.

You would have to be religious about connecting and disconnecting packs from series to parallel including the balance tabs. One mistake and something will go horribly wrong. When the packs are in the boat it is easy to misconnect something due to all the wires.

If you want to charge 10S2P in one shot invest in a charger like the iCharger 4010 which can charge two 10S packs independently.

Sorry to be the safety police, but this is asking for trouble.

Missed the in boat part. I would have no way to estimate how long it would take to charge as I use a 24v system.

I just had a pal light up one cell of one pack doing this. So this is fresh in my mind.

you're right tyler snd everybody else. would be nice to do, but mistakes happen. and it would be a very expensive mistake. tyler, once i get all 4 packs out of the boat, can't i just hook all 4 up and charge in series or am I just able to charge 2 packs at once?

Charging in series has it's issues too. Balance connectors have a specific order. Plug them in wrong and you've fried wires and possibly the pack. Use a safe parallel board, fma as example, and use a cell checker before plugging lipos into balance board.

The only way you're going to be able to do all 4 packs plugged into series and charge at once is with a charger that supports 20s and I have yet to see one.

There's good info here you may want to read up on

First off, it is a good idea to charge out of the boat where you have space and could quickly disconnect something if there was a "incident". It is safe to charge in series (i.e. charge 2x 5S packs as a single 10S pack) if you charger can balance all cells individually. For example I run a 10S2P cat with two 4S packs and two 6S packs. I connect a 4S and 6S together in series and charge it as a single 10S pack. Each cell is balanced relative to the combined pack. This also ensures the best consistency of the cells. I will charge the other pair of cells on the second channel.

I understand a $350 charger may be out of the question to do all charging functions for a 10S2P pack. So you can try the safe parallel board, but I would limit it to 2 batteries in parallel. So you will have to charge in two cycles. You can safely charge at 2C (10A for a single battery, 20A for two in parallel) to reduce the charging times, but I would not go beyond 2C.

If you are trying to run at a racing event with only the four batteries available, you really need something like the iCharger 4010.

tyler, is the icharger 4010 reliable and easy to use. my cellpro is so easy to use, basically fool proof. need all the help i can get lol!!

Mine has been very reliably. I have over 350 cycles per side. It is a little tricky to learn the initial settings and how to adjust settings, but it takes 20 min with someone who knows how to show you. It is quite easy in that it stores a charge setting and auto adjusts to the cell count. So you can hit start on a 2S or 10S pack and it will charge either at the specified amperage and cut-off voltage.
You do have to be careful on the procedure of connecting wires, particularly if charging split packs like two 5S packs a 10S pack. If using split packs, you need to unplug the balance board from the charger, then connect the two batteries to the board, then connect the balance board back to the charger. Followed by the negative battery lead and lastly the positive lead. The reason why you need to disconnect the board when connecting multiple batteries is so the charger sees all cells in a short period so it recognizes how many cells it is charging. If you were to leave the balance board connected and connect one 5S pack and then a second 5S pack it might misread the number of cells as 5 instead of 10. It is an easy procedure to remember.
