Li-po batteries installed inside case

[starbird]

Hey just a heads up to the group I've been working on installing 3 li-ion 3.7v @ 4.000 mAh (18650) these batteries are installed inside the original case of the AIM UHF. I've designed and install stalled a laser cut mounting plate over the top of the existing board. The foundation when mounted on that plate, form a solid platform to attach the new internal batteries.

I'm going to use a ribbon / connections to serve as a charging port for the lipo batteries so the the correct charging system can be used.

I'm at the point to start testing battery charge life, It should be more than 24 hours per cycle more than enough for field or service work. 

I'll try to attach a couple of photos and keep you posted on my up date.

The 2nd option will to install a bluetooth TX inside the unit so the unit can be paired with a table or perhaps a mobile phone.

Let us know how it works out. I'm not sure how well 3 cells would work with the Power AIM 120, it starts getting fussy about the voltage somewhere around 10V. I was thinking that 4 cells would be a better fit.

Dennis how is it coming with the Lifo batteries and the Blue tooth mod? Really interested, as I would like to pair the VNA with my Bluetooth in the Kindle.
