Ahh;
You're on the Council Bluffs region. Beautiful drive!! Once I had to drive from Kankakee,Il to Omaha to work on a PICU monitor, the drive through Council Bluffs and the highway was really pretty.
The units I serviced had their own internal batts, this made it so they could go from a Helio to whereever without ever losing patient data. Pretty cool.
The BMS guys were some of the brightess I'd ever talked to, and they were also smart enough to tag ALL the batteries for themselves :-D
I do not know if they are still that way since Creighton and the Uni merged some 10+ years ago, but you could ceratinly ask.
They're a bit quirky since they have to deal withall the different types of equipment and they will most certainly ask you questions to see if you know what you're doing.
However they are kind too, so I sure would not hurt to go ask.
I have several frined at Barnes here in St.Louis and they keep an eye out too, but so many of them do the same I'm not even close to being on page giga to receive any.
Best of luck!!
