As I remember it, it wasn’t very competitive at $189. I am using Deka 8GGC2 batteries in my electric Geo Tracker. They are 200 AH 6-volt gel cell batteries and weigh 70 lbs each. I am using 16 of them for 96 volts. They seem to be perforning well, but overall I have less range that I would like, so if I did it again I would probably go with some big, heavy duty 12 volts and use 12 of them, or a lighter 12-volt and use 24 of them.
I have a spreadsheet I used to compare different batteries (trade-off analysis) – write me at and I will send it to you.
What vehicle are you using? Have you selected a motor and controller yet? I will be glad to share my “lessons learned”.
