The 6v batteries I have are 283ah batteries, wouldn't a 105ah run out quicker? The cart is technically a street legal car that goes 25 mph. |

Re: 48v battery questions

Before I switched to Lithium I ran 8 Trojan T-105's which were rated at 225AH. When I switched to lithium (initially) I installed a 7 module Leaf 60AH pack. My cart had the same "run" and "distance" capacity with the 60AH lithium as it did with the 225AH Trojan's. Why? Because it's the usable amount of energy that matters. That, along with losing 400-lbs when going from 8-FLA's to a 7 module Leaf. With FLA's you only have a maximum usable volt range from 2.122-VPC to 2.017-VPC. In other words don't drop below a 50% SOC with FLA's. With lithium a max per cell volt is 4.1. (Actually 4.2) and the lowest a cell should go to is 3.5. If a lithium cell drops below 3.14-V the battery is likely damaged and in a very dangerous state. So....what I'm saying without being techno is it's tough to compare the two types of batteries and state this in layman's terms. (Or my terms) Also, since I just doubled my pack to 14 modules and increased my amp\hr from 60 to 120, I have twice the energy storage I had before. Same voltage....just more energy. For an example, if you hooked up 16 FLA's you would have twice the energy storage as you would with 8 FLA's. But you also have 500+-lbs of weight along with that. Now.....I've oversimplified this as it's not just a "volt" thing but the storage capacity of energy. The storage capacity is measured in amp\hr and a lithium battery has a greater "useable" storage capacity than the FLA's. Again....I'm likely oversimplifying this as I'm no engineer and just a novice. Those in the know will chime in and state where I'm not quite technically right. But I hope this helps. |

Re: 48v battery questions
I would guess the previous owner put the high capacity batteries in there, because those are very expensive batteries, and was probably done to get extended range.
There would be less range with a lithium pack at 105Ah. But there are other factors to consider for lithium, such as power demand from the motor. I'm sure you could get away with a 100Ah lithium pack, but for the extra cost, I don't think it would result in greatly extended range. If you're just planning to run around your neighborhood, a set of Trojan T-105 batteries should still get you in the 30+ mile range, for much less cost than the super high capacity batteries. You would be spending about $1200 on batteries, vs nearly $1800 for the higher capacity lead acid, or $2000+ for a comparable lithium pack. If you think you'll keep the cart for 10+ years, then a lithium pack might make sense. But if you take care of lead acid batteries, a set of Trojan batteries can last 8 to 10 years depending on your usage and maintenance habits. |

I don't know what kind of motor would be in a Zone cart. But probably not the same motor that's in a normal fleet golf car made for riding around on the course at 13mph. |

If I went with 180ah batteries which I can get locally, will it still hit 25mph but not keep as long of a charge or will it have less overall speed? |
