8 Volt vs 12 Volt Batteries
I currently have a 2004 Club Car 48v DS cart. The batteries are Energizer 6-EGC8 Min 110. Could they be replaced with 4-12v Batteries? What would be the pro's & con's?

Re: 8 Volt vs 12 Volt Batteries
This is the EZGO forum, but batteries are batteries.
Yes, you can run 4x12V golf cart batteries, but not automotive type batteries. Pros: Less space & weight. Cons: Less Run-Time. Think of it this way. A 48V battery pack consists of 24 two volt cells. The physically bigger (Volume of electrolyte) and heavier (Area of Lead plates) the cells, the more energy they can store. Batteries tend to come in about the same size boxes, so the 3 cells in a 6V battery are larger than the 4 cells in an 8V battery and both are larger than the 6 cells in a 12V battery. If you've got the room, 8x6V would give you the longest run-time, next would be the 6x8V you have and 4x12V would be the least. |

The T-105 is the de facto standard for golf cart batteries, so let's use it to build an 8 x 6V 48V pack. The T-875 is the mid-grade 8V, but the same size and about the same weight as the T-105. The T-1275 the typical 12V, but is both larger and heavier than the T-105 and T-875 so it comparing apple to oranges and the run-time is skewed upwards considerably. The Trojan 27TMH probably isn't used in Golf carts, but it is closer in volume and weight to the T-105 and T-875 and reflects a truer difference in Run-time. T-105 = 447 minutes @ 25A and 12.00 kWh of energy stored (0.50 kWh per cell x 24) --- Run-time = 100% T-875 = 295 minutes @ 25A and 9.06 kWh of energy stored (0.38 kWh per cell x 24) --- Run-time = 66% T-1275 = 280 minutes @ 25A and 7.96 kWh of energy stored (0.33 kWh per cell x24) --- Run-time = 63% 27TMH = 200 minutes @ 25A and 6.16 kWh of energy stored (0.26 kWh per cell x 24) --- Run-time = 45% Bottom line: For maximum Run-time use the largest and heaviest batteries you can fit in the space available. |
