Re: My Lithium Upgrade Experience
Looks great.
How much range do you get with this setup compared to lead acid setup? |

Re: My Lithium Upgrade Experience
Nice job! I looked hard a year ago at Lithium conversion for my Yamaha Drive G29 (w/500A Altrax & 9HP motor). Extra power and range would’ve been great, but decided, for now, that fire liability with an “experimental” Lithium pack was too much of an unknown. Ever seen a Samsung Galaxy 7 phone burn up? Can’t wait for a bonified certified Lithium pack for golf carts, and Elon Musk just might get it done. Must be at least a dozen Teslas in my country club community.

Re: My Lithium Upgrade Experience
A very big name we all know and trust has lithium powered carts in field testing.
I suspect we may hear something this time next year. |

I have only had this setup for a few weeks and I have never really had "brad new" lead acid batteries to test. In the past using my Dad's golf cart with 4 12volt lead acid batteries - we could play 1 round of golf but if we ever played 36 we would rent another cart from the golf course as we never thought it had the range to make it around twice. My best guest would be 3-4x the range with my 120ah setup. I played 2 rounds of golf and drove around the community for about 6 miles - and it still felt like we hat a lot left. I was at 54 v on my meter and 52 is when I probably need to charge. Nick at Evbattery center said when I get to 52v I have about 8-9 miles left on flat roads. He said normally I should get 4 round of golf or go 4 days with 1 round per day between charges. I know there is NO way the lead acid setup we had before could do that. That is why with my next go around I will opt for the smaller 52-60AH battery setup. Plus they will be 60lbs lighter. |

Someday soon someone will be making a lithium drop in replacement, hopefully soon, and advertise it. If the range is much further, I will be one of the first to jump on that wagon. I still do not know how much the range increases, would be a nice fact to have.... |

Re: My Lithium Upgrade Experience
Curious. Will a lithium pack as described at the start of the post produce the high starting amperages of a hot motor? Are they affected by the cold as much as FLA? I know my Li cordless tools work better in the cold than ni-cads is it the same with bigger loads? Around here "cordless" cars get around half the range in winter than in summer but there is a heater and other factors that come into play.

Re: My Lithium Upgrade Experience
I am certainly interested in going to Lithium batteries in the future but I have just bought my cart with new lead acid batteries which should last 4 years or so. By then I'm hopeful that Lithiums will be available more readily and at a more attractive price. Keep your stories coming as it makes great reading.

Re: My Lithium Upgrade Experience
I think that expecting 16 years is a pipe dream. There is no data that says they will last that long. I expect mine to last somewhere between 5 and 10 years. If they go more, great! I take good care of them but 10 years is a long time for any kind of battery to last.

Maybe if I had went with the smaller pack 7-10 years. But that would be due to them not having enough range for me to make it through a round of golf. The 120ah pack I got is way over kill. I probably play 36 holes of golf 3-4 times a year. All the other times I golf I would be recharging every night. The battery pack sits in a dry storage compartment below the seat. It should never see extreme cold or heat. The BMS that comes with it controls charging - being careful to balance the batteries and not over charge. If one cell were to go bad it would not be that difficult to replace just the one cell. They are readily available on ebay and in the used parts auto world. Then of course these will continue to just get cheaper and hold more charge. In 10 years buying a lead acid batteries for a golf cart might sound crazy... |
