  Hi!
  Aren’t the tabs of the single lipo cells made of aluminium which is quite hard to solder?
  I guess you could get a better formfactor by putting the cells in parallel (e.g. 1S3P). So you could keep roughly the outline of the board.

  Regards from germany!

    I just looked at the comments over at the reseller website and someone pointed out the same potential issue. Not being a RC expert I also would be sure those cells could be soldered without any risks of burning my house.

  Does that battery have some internal current limit or protection circuit?

    No. You can’t really get 100A+ and still have internal protection.

  Hi Dave, would you do an USB power supply project that utilize the standard 18650 battery? I guess the 18650 is also powerful enough, and, easier to replace I think.

  Dave, make sure to measure the charge/discharge voltages of that Turnigy charger with a multimeter. They are occasionally known to be slightly out of calibration. Might damage the LiPo cell. Just a heads up. A teardown would also be cool…and perhaps a physical calibration when needed?

  Thanks

  dave,

  I need to implement this battery in a cct that is portable and i will not be using a very high current.

  Is it possible to know how long would the charge inside the battery last if consumed only in 1-2 mAps 24×7 a day?

  Would there be a discharge after some time? may be after 30 days? how long would the charge last? would Ni metal hydride batteries be better is this regard?
