Battery/charge connectors different between v2.2 and v2.3
I purchased Lipo batteries and solar cells when you were selling v2.2. I found that the battery and solar connectors are different on v2.3. Do you have a converter or the female end I can place on the battery/solar cell?
Hi,maybe you can use this Converter(http://www.seeedstudio.com/depot/jst-254mm-to-20mm-converter-pack-p-1030.html?cPath=178_179)
After connecting EN to PD5 to enable XBee power control my XBee will not power up. My XBee has its sleep mode set to 1 (Hibernate) and I toggled power on pin 5 but there is no difference. I then used my multimeter to test connectivity between digital pin 5 and pin 9 on the xbee and there is no connection. Can you help me to understand the problem
Hi Jacket, thanks for the reply. I've consulted the EAGLE file and I can't locate the connection between EN and VCC. If you could provide a more detailed answer I would be happy to edit the wiki with the information.

Hi James.Just cut the track between EN and VCC and put a solder blob between EN and PD5. You can control XBee Power by Digital Pin 5 (PD5).Please see the eagle file to find more information.
Hi there,
Can the Stalker charge this battery? http://www.seeedstudio.com/depot/lithium-ion-polymer-battery-pack-6a-p-602.html?cPath=178_183
Or does it only charge 1 cell batteries?
Yes, it can be used to charge this 6A lithium battery , note that only charged for one lithium battery. ( N cell pack + battery management circuit = one lithium battery )
I find that this board is great, even though I have had issues with the RTC. This is because the I2C data line pull up resistors (10K) are too weak and this corrupts data to/from the RTC. I solved this on multiple stalkers by adding another 10K in parallel to reduce pull up to 5K, which is recommended for I2C. If not for I2C issue making me tear my hair out then I would have given it 5 stars.

I am interested in the Stalker V2 and GSM shield, but see from comments that this combination will not work with the sola panel and Li On battery ......... why????

I would recommend that for the next stalker to take care of the fact that one cannot use the solar and lipo inputs when using a shield!
And you should stipulate in red that it needs an ftdi to connect it to the computer.
Otherwise great product!
