You did not state what the ampere hour rating of these batteries are. I was searching the web and came across the Interstate Battery specifications for the 6-volt battery. The local independent auto Parts Store which I have been going to since the 50's started to handle the Interstate Battery line which is only 5 blocks from me and delivers items to my house.
So I went to the Parts Store (which is actual name of the store) and I notice the Interstate Battery battery truck was there. I walk in and I want to see the data and specifications of these batteries. The Interstate battery person said, I have it right here in this book that was laying on the counter. I said, I like to see the data on the 250 ah 6-volt battery. He said they do not make this battery over 220 ah, but we furnish the 250 ah one which we get from the U.S. Battery Co. I said I will take it without any hesitation. I said I need for them to be all the same manufacture date, auto post with deep imbedded stud (use this stud connection for a BMS and also to put a greater internal pressure of the auto post against the internal surfaces of a battery clamp. I also wanted to have these battery balance (battery balance means the ampere hour and voltage and the deep cycle cranking ampere at 75 ampere for a certain amount of time within a 0.1 V, 5% A and AH of each other. The Interstate guy said this will about double the cost of the battery as a option cost. You can do this testing yourself with the equipment we furnish the Parts Store battery shop. We normally ship 240 of these batteries were you can test out the best 30 batteries you need. Interstate deliver the batteries right to my house. The batteries were in a U.S. Battery package. I pick out 30 batteries that where match with a voltage of 6.44 volts and the cranking ampere was at 1000 amp plus or minus 5 ampere. Had to go two pallets of batteries to get this tolerance. Knowing that the actual drive test and recharge may change this results, One battery of 30 batteries was out of tolerance, so they change this battery for me. These batteries where install on September 4 2009 and had put on 2729 cycles on them driving only 4165 miles. In this roller coaster roads, the actual motor on time is about 3000 miles and the motor off time is the remainder. Today the AH per mile and charging time over the same exact route and temperature is still 3.3 ah per mile and 7.5 minutes of charging at 20 amperes at 250 volts. The cost of the batteries ran $125.00 for the 250 AH.

That's $140 per battery. This seems quite high for Interstate, which is not a premium battery. Most dealers will "make a deal" when you are buying that many batteries. Otherwise, just walk. There's no sense in paying full premium price for a purchase this large. I guess I'm cheap. :-) I bought my current set of golf cart batteries from Sam's Club for $77 per battery. I see they want $84 today, but I'll bet they'll come down to $80 or less for a quantity purchase. Prior to this pack, I bought a set of 22 US Battery US-145xc for $135 each. -- There are few industries with more BS than the battery industry. Elon Musk -- Lee A.
