Sovereign GT and Elite battery pack options

Got a couple of rechargeable battery packs so I took one pack just to see how cheap and effective this method would be. My goal the batteries should be fully charged in 8-10 hours so a NIMH 900 mah battery might work. Another important factor this pack must hold a charge for at least 10 hours while using in field. Forgot to mention 10 batteries must fit in the Sovereign battery pack, limited space) so AAA batteries could work.Photo of my Frankinstein battery pack.
 
Final outcome on the first run before needing a charge 13 hours 47 minutes and 26 seconds. Not bad for cheap Harbor Freight Thunderbolt AAA batteries. Could have charged longer, we'll see what will happen on the second run before a charge is required. HH Ron
 
Great results... i personally dont know much about batteries.. ive always had concerns about using the 1.2v rechargables vs regular 1.5v. Why dont they make rechargables in 1.5v? nice work ron...
 
The flat batteries used in the stock battery packs are 1.2V also. You have a good point if the 1.5V batteries were used it would eliminate two batteries, less weight, my guess the extra 2 cells would hold the charge much longer. With these AAA batteries used in the pack I threw together it has a decent time before a charge is needed and charges before the following day. Best of all with the holders and batteries I used will cost under $30. These are low tech old school batteries that are not going to start fires. Note Warning: too many people with their builds have the negative and positive poles on the opposite ends, this will destroy the Sovereign, have seen a dozen of these costly mistakes. Thanks
 
I like the looks of what you have done to this pack and know there is no reason this wont work as you are using the 10 batteries as required. I tried replacing the factory batteries like what was in the rechargeable pack to one that had more run time, but it is hard to solder all those batteries and it worked until I put the cover back on and being it was tight fit I shorted out something and let me tell you it does catch fire easy before getting it back apart. It burned up the curcuit board and melted some of the plastic of the case.
My next project was using the case and added a Lithum battery that sits on the outside of the case with velco for time being and made some connection so the battery can be unplugged from my Battery pack and charged with my special charger that monitors the voltage like it is suppose to. This is my back up pack when the main one runs low so I can keep right on detecting. It works, but I like your set up much better and may make some thing like that.
Good Idea Ron.

Rick the problem with the flat batteries they need extreme heat quick, to solder in our hobby most people don't use or need this equipment. With my soldering low heat iron I would only destroy or melt the battery trying to solder a pack . Thanks Ron
