6v V2 Battery Options

<< < (2/2)

johnw:
I’m thinking about bringing my v2 out of retirement. Is this talentcell still the best option?

Also I’ll need to hack an old power cable from a long dead battery. Is the polarity an issue with the v2?

Don't forget the power in on the V2 is a 4 pin XLR connector. maybe PM Ted to see if he has a schematic or something.

johnw:
Thanks. I have a 4 pin xlr cable that went to the output on an older battery. I was going to terminate the battery side but don’t remember if the v2 is polarity specific.

POWER SUPPLY CONNECTIONS
A four pin XLR connector is used for the DC power input of the V2. The V2 can be ordered
to operate from either 6 or 12 Volt power sources. Pins 1 and 2 are ground and pins 3 and
4 are either 6 or 12V DC. To avoid compatibility problems it is recommended that 6 Volt
systems be wired to use pin 3 for hot (+6v) and pin 2 for ground while 12 Volt systems
should be wired to use pin 4 for hot (+12v) and pin 1 for ground. The V2 current draw
ranges from .38A to .62A depending on the microphone used.

edit- I see beatkilla beat me to it!
