Battery Research
I organized my shop today in preperation for the disassembly stage of the project. I also did some research on batteries. My plan is to use 12 12Volt gel filled deep cycle batteries.
I recieved an answer to my email from Electro Automotive. Although I can use the 12 12 volt gel filled batteries, and accomplish my mission, I have decided to go with 18 8volt flooded golf cart batteries. Here is why Wh=Voltage of Pack X Ah of each battery. With the 8 volt flooded batteries I can get 105 Ah (1 hr rate) X144Volts = 15120 Watt Hours. Exceptional.
So Now I know I will be using an AC motor, Driver, and 18 8volt golf cart batteries for power, plus one 12 Volt battery for accessories. Perfect…now all I have to do is design where I am going to put the batteries.

As a owner of a GTE I strongly advise against the fitment of flooded batteries, too much work is involved it checking and toping up the batteries

Brett, I have done the research on batteries for my particular application. I will be installing an automatic watering device. I will only have to check the batteries and see that they are full. If your interested in an autofill device, contact Mike Brown at http://www.electroauto.com

Brett, after careful consideration and calculation, I have decided to use 12 12 volt deka dominator batteries for my main pak. This will lighten the load by about 600lbs and they are a low maintenance battery. I will still be getting approx 70mi range and will be able to fulfill my cars mission statement. Thank you so much for your input on this very important decision.

Hi, I just saw your post as a newby in the Bradley GT forum, I’m also a participant of it.
My approach to you is for the fallowing, I will be converting my GT II also in electric and could use some help in the design of the batteries subframe upon your learning curve with yours.
I researched in the original Bradley frame and finding it very unstable and sort of confusing, I may be wrong.
Some pointers will be great, a pictorial design will be much better and commentaries on what NOT to do will be most beneficial.
I also was looking at the DEKA AGM line. Cheapest I could find localy was $202.00.
I can be contact at “mrbigh@lipog.org”
