Hi all,
Just received this http://www.hobbyking.com/hobbyking/...00Wx2_Battery_charger_discharger_400w_V2.html. Will be ordering next week the lipo 6S 20C 5000 mah packs.

I plan to hook 2 in series for 44 volts and packs in parallel for amp hours yet to be determine for total capacity.

Several questions, Can I leave the packs in series and connect to the charger or do I have to seperate and charge as 2 seperate packs? In series pack 1 + would be connected to pack 2 -.

Can I permanently leave the packs and balance plugs connected to the charger while off, and if so will the charger draw current and how much?

Thanks Ray
 
You have to disconnect the pack from series. That's how cheaper chargers like this work.
 
Thanks for the replys, I thought so. Now can I leave the balance connectors plugged in while I run the bike with the power connectors disconnected or do I also have to unplug them also?

And/Or leave everything connected in series while the charger is off and when I go to charge simply disconnect the series connector when charging?

I'm finding this second question a bit vague, so here's an answer, that may even be close to an answer to your question.

You are saying series them, then paralell. I'm saying, you should make paralell connections, then series connect the paralelled groups of packs.

Say you have 4 lipos. They are paralellel connected in pairs, say 6s 10 ah. They are paralelled at the balance wires too.

To run, you of course connect the main power wires in series, and connect to the controller.

To charge you disconnect the series connection, and each pack is seperately connected to one of your chargers, and charged as a 6s 10 ah pack.

To balance charge, you also connect your paralelled balance wires to the charger, and select balance charge.

In this scenario, all you would be doing is leaving the paralelled balance wires alone, unless you want to balance charge.
 
Hi Dogman, your reply is why If I wrote an incident report I had someone else proof read it as it made a perfect sense to me but not to the person reading it.

Yes in your senario I would have 2 sets of 2 packs in parallel then in series. Basically be running 44 volts with 10 amp hours. To charge I would break the series connection and hook the 2 sets of parallel packs to the dual charger to charge and balance in 2 sets of 2 in parallel. I am going to be using parallel balance boards for multiple pack connections.

I would like to leave the battery packs connected to the charger when Not charging. When powering the controller all I would do is connect the series connect and to charge disconnect this connector. This would make it a simple one plug connect or disconnect. Would this work? Will the the charger when off discharge the battery packs as the balancing and discharge leads would constantly connected? Will it damage the charger?

Hope that make sense and thanks for all your thoughts. Ray
 
i would heavily advise against leaving the balance and or the main charger leads connected ile the battery is connected in series as the non isolated chargers will conduct via their ground weather they are powers up or not
