My question is, will the electronic protection circuits on this pack interfere with the charging circuits on the board? The standard li-ion AAA batteries don't seem to have any obvious protection circuits on them.

Thanks

You should be fine with this battery but do not remove the protection board
Unless the unit requires a different cut off voltage to the batteries then that could be a problem I have only seen this a couple of times
Your unit should work fine with it
