Re: RXV with Lithium Batteries
its 5/20/2121: one month since my new Lithium Battery pack install.
TODAY IT FAILED AGAIN!!! 4th pack in less than a year!~!! Either this cart is CRAP or 4 lithium's are CRAP! on 4/19/2021 I wrote:old post I know, but I am having same issues. 2015 Rxv 48V stock curtis controller. im on my 3rd lithium battery pack in 2 years. here is what I have: ePOWER4803E are integrated golf car battery systems with a 48V 3KWh Lithium Ion battery pack. The battery configuration is a 16s1p 60Ah pack. It is typically programmed with 80%DOD, or 2.4KWh usable storage capacity. 1st pack dropped 6 cells in 6 months 2nd pack dropped 9 cells in 3 months. last pack lasted 2 months before dropping 9 cells. Total lock up on cart when voltage drops. |

Re: RXV with Lithium Batteries
You mentioned moving up to the 100Ah pack a while back.
Is the 100 failing or did you stick with the 60? |

Re: RXV with Lithium Batteries
same old pack, the manufacture replaced the boards in the old lithium pack, said that was my problem. they promised to upgrade me to a 105AH if it failed again. We will see today what they say.

Re: RXV with Lithium Batteries
Looking at their website, in the manuals section, the specs for your pack (4803e) specifically call out that it's not rated for "high speed motors".
The ePower 4803 model is not recommended for use with high speed motors or controllers. The ePower 4805 model is capable of higher discharge current and is more suitable for such vehicles. So they call out the "high output" version by model number, but it doesn't appear to be found on their website. I'd guess, based on the symptoms you've described and the red boxed call out on the specs, that this pack just can't handle sustained output demanded by the motor/controller. https://www.elitepowersolutions.com/manuals If you want to view the specs, download the file then add .pdf to the end of the filename so your computer can recognize it and open it. Here's the relevant specs from that page: Model ePOWER4803c/e Nominal Voltage 51.2 VDC Battery Capacity 60 Ah / 3.07 kWh Usable Capacity 48Ah / 2.45 kWh Discharging Parameters Maximum Recommended Motor/Controller Rating 5 kW or 6.3 HP (Continuous Rating) Max Continuous Current 100 A Max Discharging Current (< 10 Sec) 180 A Min System Voltage 47.0 |

Re: RXV with Lithium Batteries
I have a 2017 RXV and just converted to the Dakota Lithium 48V 96AH battery. So far no issues. I added a battery shunt and gauge to monitor discharge rate and that seems to be working as well. I would like to take the original charging port out of the equation but my understanding is that in order for the cart to function the blue wire from the charging port needs to be connected to the + side of the battery. Would someone smarter than me please weigh in as currently I have the old charging port still connected along with the gray temperature sensor wire but i'm now using a lithium charger with an Anderson connection. My hope is to remove the old charging port and put the Anderson receptacle in its place.
Thanks in advance - This is a great resource for all! |
