    Probably not. You can charge in series or in parallel. In parallel all the positives are connected and all the negatives are connected. The rule for parallel is that you increase the capacity but not the volts. So if your batteries are 260mah and single cell you charge at 1S (3.7V nominal) and 1.5amps. If your adapter connects them in series, which would be better in your case, you add the voltages and keep the same capacity. Series is the usual way batteries are connected to get more power. Its positve to negative for each battery like in a torch. In series you would charge at 6S (22.2V nominal) and either 200 or 300ma.

    If you charge in series the state of charge of each battery is not a problem. Any battery that fails will stop the charge. That is not true in parallel charging. Series charging cannot be used with packs above 3S as most chargers only go up to 6S.

    I would charge each battery on its own first and also check the volts before charging. It should be between 3.7 and 3.9V. Outside this range I would return as faulty.

      I was thinking of using Pylons. I don't know the practicalities, but a lot of fields have pylons close by. They produce magnetic fields and if these were monitored, to check for interference levels, they would produce a small current. Perhaps an amp or so could be generated. This could be used to power the batteries controlling the monitoring equipment. I don't expect the electricity people would or could object to such monitoring equipment. Especially if it were constructed in such a way that it did not detract from the visual amenity of the site.

        No Loz don't do that, you'll fry the little bu**ers ! Charge them at 3.7 volts ( 1 S ) and 0.7 amp per cell if using a parrallel cell adaptor for the stock lipos. The stock Celectra charger is meant to charge one cell at 0.7 amp, but actually barely manages 0.5. I use an Astroid multi adptr to charge 6 at a time and set it at 4.2 amps, works fine.

          Cheers, I'm going to find out if the 6 way adapter is wired parallel or series before I do anything
