Why bluetooth Bee 2.0 doesn't work with Lipo?

A RobotShop UAV? No - there are other more pressing priorities at this time. Any ideas what features you’d like to see? Size? Price point?

We have changed the XBee and Bluetooth kits to now include RB-Spa-556, which is a 2Ah battery which solves the issue. Please contact us via the support center with your order or invoice number c/o Exchanges / Returns department.

We work internally with the same robot using the 2Ah battery along with XBee or Bluetooth with no issue. Is this happening on all the devices or just one?

That is indeed very disconcerting. We believed you were using a smaller LiPo battery which usually causes this problem. your robot should be able to power up without issues. Are all your power signals at the proper level (3.3 and 5V)? Is your battery being charged properly (it might take a very long time to charge it with the built-in charger)?
