What is the point of having all this battery capacity if I can't use it?
Please help my caveman brain understand something. I'm trying to be a responsible cart owner and charge the cart before its SOC is below 60% or so based on my digital battery meter. Yes of course I want the batteries to last a long time. But what is the point of having all this battery capacity if I can never use it?

I think you can use it...you just have to buy batteries more often! The trade is miles per charge vs miles over battery life.

Even in shallow discharge situation 20% of 1200 amp hours is nearly 20% less than 20% of 1470 ah.

You can use it all, just the battery pack won’t last as long.
There is a finite number of times the battery can be cycled (discharged then charged) before the lead plates erode away. Charging a lead acid battery forces lead to come off of the plates and the loss of lead means an eventual and gradual loss of overall battery capacity. The less the battery is discharged, the less it need to be charged again in order to maintain 100% SOC. There are some charts available from battery manufacturers like US battery or Trojan that estimate the number of total expected cycles you should expect from a battery based on regular discharge percentage. A battery that is discharged more than 50% on a regular basis has far less than half the lifespan of a battery which is only discharged to 80%. It doesn’t mean you Can’t discharge the pack further. You can use the pack however you want or need. But the more you discharge the pack, the shorter the overall lifespan of the pack will be, and the overall capacity of the pack will also decrease faster. It mostly means you will have to replace the pack more often. |

i subscribed to the plugged in when not driving it method for a while
before i figured out driving 100 yards would add another 10 hr charge cycle installed a digital meter and now charge at 50 volts that can be as much as a week or two down the road |

I agree is seams Crazy, If I had a choice I would have bought a gasser. My Campground only allows electric. Only after Purchase of cart and new FLAs did I find out how much goes into maintaining them... And I stressed quite a bit over how and what to do to prolong them as best I can.
I have all but given up... I will do what is recommended and when they die I will look into the Lithium options. |
