suitable battery pack for Axon II

[aaa3a]

i am a new to axon and need to know what is the suitable battery pack to work with Axon II no dc motors just voice recognition module and sonar sensor the dc and servo motors supplied by separate battery pack
i have 2 battery pack one with specs.
                                               6 volt 4Ah
                                  initial current less than 1.20A
                                  cycle      use  :7.20-7.50 volt
                                  standby use  :6.75-6.90 volt

and the other is 5 cells 1.2volt 2200mAh connected in series to give around 6 volt

can i use the first one with Axon II or should i use the second

what is the maximum volt and amp for Axon II

Maximum voltage.

The way you ask the question in the last part of your line, I suspect you don't have a clear understanding of voltage/current (which is OK, takes a while...).  Current only matters if the battery can supply less than what the board+attachments is trying to use.  It doesn't matter if the battery can supply 100x the current you need; e.g. you can power a tiny LED off of a car battery, with the proper resistor.  I'm pretty sure the 1.2A battery will be enough current (I've not used the voice recognition module), and the 5x1.2V pack probably supplies at least that much current if needed.
