Default EZGO TXT Lithium Upgrade

I have a 2005 PDS 36v and the batteries are shot. Can anybody recommend if a Lithium battery upgrade is worth it? Max distance traveled is 15 miles, but typically 5-10.

If you are looking for cost savings, may not be worth it. If you are looking for weight savings, pack performance, longest life, no acid mess/corrosion, no water maintenance, may be a good plan for you. I have built several lithium setups, and cost savings is not on my list of selling points. Your range needs are no problem at all. And a 100ah lithium pack delivers the same amount of energy as a lead T-875 pack when both are configured for 48v use (and tested with the industry standard Lester discharge machine).

What price range are you talking about? I think this might be worth it if I don't have to worry about changing out batteries every 5 years. The performance would of course be something I am interested in as well. I am running 36v and I don't want to replace the controller and motor if I don't have to.

Well, ours are pretty pricey. Over 3k added to cost of a new cart. But that's a full system, cells, charger, battery management system, and a 7 year full warranty. We do not sell them outside our area, or for self install. You could build a system yourself for a lot less out of used Nissan leaf cells (as has been done on this site several times). The cells can be configured for any voltage you need, and stock controller & motor can be used.

Thanks for the info. I can make a case for it if the price is equal or less than 2 new sets of batteries. My assumption would be the lithium batteries would last at least as long if not longer.

Just know what your getting into. These are not your grandfather's batteries. All I will say is that you have seen the "e-cigerett's" blow up in smokers pockets, and you have seen the "hover-board" craze lithium batteries catch fire for no apparent reason (and, of course.....there are reasons) So, if you are not an Engineer or someone who has a background of heavy science, it's not like putting together a flashlight.

Just sayin...........

Cold temps will reduce range with Lithium batteries also. All batteries are subject to performance variation with temperature. Basic Chemistry. I am happy with my Lithium upgrade but I am hesitant to recommend it to anyone without some electrical experience. FLA batteries handle abuse much better. A single over discharge of a Lithium pack will ruin it. Overcharging a Lithium pack can cause a spectacular fire. For me, the interest in doing something different and the 250 plus pounds weight savings is worth it.

Luckily I don't have to worry about the cold. My understanding is that the BMS will take care of balancing and preventing overcharging. A concern would be a complete discharge and rendering the batteries useless.
