Step one of getting ready to experiment with NMS was to make Roli run more than 15 minutes on a charge. A little surgical procedure with a dremel, and he now has a 7200 mah battery inside the body.

Tip on battery Life....I was using the cheaper RC Lipo/Nimh chargers that are even supposed to balance Lipo batteries...They do not work right and in fact damage the life of Lipo batteries. Use the 70.00$ Imax B6 or B6 Mini the newest one. The best charger ever! I brought 6 Dead Lipo batteries back to full Life after sitting dead for 3 years,old chargers would never charge them saying error,no balance either. The Imax does every battery known to man and very accurately balances every Lipo cell ,also has volt meter,Ammeter, lets you discharge/charge in full cycle for Nimh batteries. For storing battery can set proper voltage. I even got 1 Lipo fully charged but did have 1 cell leaked a bit of gas,The Imax tells you that and while fully charged shows the 2 cell Lipo not balancing well But it still works as fully charged with a tiny amount of bloating(not recommended to keep using) Shows how good this Charger is.
Most good quality LIPo chargers will not charge a LiPo if it below a certain voltage. This is because the charger has a safety feature that assumes the battery is suspect or faulty and may blow up. You can get around this by providing a constant current, constant voltage charge and do one cell at a time at a low amperage (less than 1C) and keep an eye on it, making sure it is not getting hot. Get each cell up over about 3v and it will happily ballance charge again.
1 trick I saw on YouTube, if you have a near dead Lipo and no charger will work, set the charger to trickle charge on the Nimh or Nickel battery setting. After it gets back in target voltage,switch to Lipo balance setting,then good as new if no battery swelling.
