What Is The Lowest Voltage To Safely Run A 48v Pack?

[Slats]

I know to leave them charging between uses, but I'm wondering if I make a single trip how low the voltage can be before I start to harm the battery. Thanks!

50%
according to the below chart ... 48.41 volts

Thanks Crash, I saw the chart but wasn't sure about the 50%.

50% is when most battery makers say to charge, a digital volt meter installed on your cart is like a gas gauge for a gas cart, so at anytime, you can look at pack voltage and "know" their state of charge. also download , print and laminate the chart posted, and keep in the glove box or somewhere with the cart until you get the different %'s memorized

If I run it 16mi. it gets to 50%. I'm in a rural area and it is a 15mi. round trip to a shopping center. Does it damage the batteries to run below 50%. Also curious, without finding out the hard way how, much further I can safely go without getting us stranded. Thanks!

not sure about damage, but as long as you keep them full of water, and charged back up at round the 50% range, you should be fine. you are at the recommended limit of your current pack at 16 mile range, if the pack is at or around the 50% state of charge after 16 miles, obviously you can run them down further, but keep in mind that if you are using the factory powerdrive charger, their is a point of low voltage that the charger will not turn on to do a recharge if they are too low.

This chart may be of some interest. Comes from the Trojan web site.

in theory you could run them every day to 50% all that happens is you loose time off your batteries life , but well maintained batteries still die someday

as for how far you can push your cart below the 50% (48.4v)
i would say it will fail at (46v )10%

i have a 36v and have limped in at 31v

Trojan says if you discharge below 80% (20% remaining) you WILL damage the battery. Otherwise, in general the deeper the discharge per cycle the less total cycles are available so going below 50% doesn't harm the battery per say but the more frequently you do it reduces useful life.

A "cycle" to me means: starting with a full charge run the cart for awhile and charge it fully when done for the day. I think there is a more "elaborate" definition of a cycle is used by the battery companies but my pea brain can't remember it.

Thanks everybody. I learned a lot!
