Yes, charge each as a 1s pack, then connect them in series to double the voltage to give a 2s pack for running.

A standard full size 2S pack won't normally fit in a B44, they use saddle packs.

Venom saddle packs look like this. Not the best picture, but notice the supplied charging adapter includes a jumper wire (the double banana in the back) for the series connection. And the packs do not have a 2mm port for attaching the full size pack balance wire. Each saddle is a 1S as others have also mentioned.

I guess the reading comprehension has dropped in this country, He has TWO 2S packs, ran in series equals=4 cells.

NOT 1S packs. NOT 2X1S packs in series, but two individual 2S packs. he confirmed that EACH pack is 2S, NOT 1S

That's pretty simple right? You guys have at it, he'll be so confused he won't know what to do.

Just to settle this, OP can you post a picture of both batteries labels? That will show what cell count they are.

then why did he say saddles? :confused: 2s2p (which he said he has) is essentially a 2s made of 4 lipo cells. but i don't know any saddles that are wire like that. they are usually (all that i know) wired as 2s1p. and these are saddles, since he said they were going in a b44. and if they are saddles, they each say 2s on the case, as you don't run just ½ of a lipo saddle pack as a single 1s battery.

just as a side note. who runs 4s in a 4wd buggy?

im not sure you could even get standard 4s batteries to fit. i think you would have to use flight packs.

He confirmed each battery said 2S/ 7.4v on it, back on page one, when I ask for verification of what EACH battery said. Hooked in series, that's 4S. That's why I would like to see a picture to put this to rest. He's new and sure doesn't need any accidents. You can certainly charge dual 2S lipos with the right charger, but then again, he's new.

Just need to make sure what he has before the proper procedure can be explained on charging.

here i meant 2s 3p. all this is getting jumbled in my head :lol:

what if he had these though.

interesting...wired as 2s2p? that would give a 2s, but less cap over a 2s3p. Cheap.

I understand what Dave is saying, but OP claims it says 2S/ 7.4 volts on it. If it's a dual cell wired internally as a single, how can a charger monitor each of the two cells in the pack during charging? You would have to have a parallel board for each 2S connector, EACH battery having 2 cells lol. Now as to who runs dual 7.4 volt batteries in series, 14.8/ fully charged is 16.8 volts, which equals 4S, apparently everyone that runs dual seried packs of this type, is running at 4S voltage.

No battery manufacturer would ever label a single battery with combined voltage of two, assuming you will be using them in pairs. That's against the law, feds would be all over that. If a battery is lost, the improper label would cause improper charging.

Lol, I think we need a picture of both packs.

...venom does.

^that battery would fit all th criteria for what the op has listed. 2s2p, 7.4 on each pack, venom.

Lol, so that means, per the label, I can charge each at 7.4 volts, and then hook them in series and run them, right? And not have 14.8 (4S) volts shooting through my system. How that could not happen, eludes me lol.

it is labeled as a 2s2p pack though, so technically to complete the circuit, you have to wire them in series. :lol:

Nope, per the label each battery is 2S 7.4 volts (min discharge is 6.0 volts), I looked lol. That's why we need to make sure we all on the same page.

Ok ok. it is a saddle, and should be wired as such. probably something about that in the instructions.
