Re: How do you know when to stop driving?
if i may chime in here.. Im curious myself as to what kind of voltage to look for while cruising.. if i have the skinny pedal all the way down after a full charge itll sit at about 48.6-8 flat out .. and one the batteries start to drain ive had it down to 47.0 flat out but is that bad ?

Re: How do you know when to stop driving?
The charge percentage is calculated by the controller and reads out on the SOC display. There is a calibration factor in the controller, set to 80 A/H (50% SOC) by default. This assumes a battery bank of near 160 A/H (4 12 volt batteries in series, 155 A/H typical). That value can be reprogrammed to increase the accuracy of the SOC guage. As batteries age, their A/H capacity drops, hence the inaccuracies caused by the default value. The controller does a pretty good job of keeping track of consumed A/H. It tries to calculate pack A/H through repeated charge/discharge cycles, but it does not internally adjust the 50% SOC starting setpoint. If you change batteries to a different A/H capacity, that setpoint should be changed. My SOC guage is working great with my lithium pack now.

I'm going to get with the seller and see what he says. If anything changes I'll post back. |

Re: How do you know when to stop driving?
Sorry, missed the last 2 posts.
Gallachera89, I don't think you can rely on the gauge when driving. Mine is all over the place with I drive flat out. Someone smarter than may know for sure. BobBoyce, so you're saying we just need to live with the percentage it shows? Your information is great, but whoosh, it went right over my head ;) |

and thank you 69Stang NCPW Im aware, i should have been more specific, i dont believe mine has ever gone below 49 to be honest.. I usually determine when i need to head home while cruising .. If im wide open and the meter is reading 47.0v i know i am at about 75%ish and i know i should probably head in .. just wasn't sure if there was any correlation in the 2 |

Re: How do you know when to stop driving?
When I had my RXV built I went with this setup forgoing the factory gage or similar ones altogether. Both of these are wired directly to the battery pack and on all the time. They could be switched but I chose not to.
The segmented gage is generally maligned on this forum but this one is the Curtis model 906. When the factories (EZGO, CC or Yamaha) install a battery gage on their carts it is generally this one. It is pretty much standard equipment on the thousands of carts in the city I live in. They have worked fine for me on several carts over 18 years. I tell people that drive the cart that if they are not already returning bring the cart back to its' charger when the gage reads half. The digital meters are technically more accurate because they are displaying actual volts. The problem with them is they are near instantaneous and cycle while your driving. You also have to stop and let the battery pack stabilize for about 15 minutes to get an accurate reading of actual state of charge and then you have to memorize the chart or tape a copy to the dash or something. I think it is good to have it however, because you can use it to monitor the packs' general health. The women and house guests that use my cart object to it with enthusiasm. I put this chart on the windshield. After 2+ years nobody has ever asked what it was or ever looked at it far as I know. |

Re: How do you know when to stop driving?
Here's what I got back form the seller about only showing 91%:
"about 3% each battery not getting not getting fully charged ! I will bet that your charger only is a 13 amp out put ! It takes a 15 to 20 amp chargers to bring batteries up to 100% .. . Been through this subject many times . I build custom golf carts primarily working with RXVs ,. I have two transformer base chargers I use 15 amp . Brings most batteries up to 100% .. depending on age and condition.. feel free to call me if you like ." He's correct about my charger, only 13 amps out. |
