Anybody had issues with the wiring on these batteries? The connection to either the battery or discharge plug seems to have problems on mine - wiggling the wire can disrupt power.
I’m trying to create my own protection circuit. How low can these batteries safely be drained?

Has anyone rigged this to produce constant power? A constant current regulator helped, but the output power still fluctuates more than I can handle.
1) This (http://www.mouser.com/ProductDetail/Texas-Instruments/LM317KCT/?qs=TB/Q0sBK/Gcz1btw204Pbw==) will help regulate the current. Figure 9 in the data sheet has a schematic - adjust the resistor for different currents.
2) Watch out! There’s no IR filter in this module.

Matt - did you ever solve your problem? I’m having the same one!
edit I solved my problem - two pins on my Arduino were dead, causing the initialization to fail.
No public wish lists :(
