Charging 2 lipos
Hi, this is a stupid question but, i have 2 7.4v lipos aand i want to charge them as 14.8v. To do this i gotta have the 1st dean positive, negative parallel to the 2nd dean and then negative. I have done with my NiMH packs but want to do it with my lipos. The lipos are the same brand and spec.

My question is, is this dangerous? Has anyone done this?

You won't be able to balance them together with that setup unless you make up a custom balance plug as well.

You can also get an adapter for doing exactly what you are asking, XtremeRC sells them for like $10 or less I believe. You plug a deans from your charger into the adapter and then the balance plugs from your packs into that. Do not nook the deans up from your packs... trust me! LOL!

You end up charging though your balance leads but I have done it @ 5.6 amps before with no problems. Charging this way does take longer though, especially if the packs are out of balance a bit or you have different resistance in the cells.

Personally I would just suggest picking up one of the A6/B6 X-Charger's from Xtreme for like less than $50 now and charging the packs seperately, it will be quicker and in the long run you will like that setup better I think.
