If you have an Alltrax controller you can set the controller for HV and LV shutdowns as well. It's just that the controller can NOT help you on the HV cutoff during the charging phase. |

Re: 92 CC DS gas, convert to lithium electric rebuild thread
First off, my knowledge with Club Cars is nowhere near what Dave can provide you.
On that note, with your Leaf setup and your stated need of using the cart for hunting, a simple series cart would benefit you over a Sepex, IMO. The series cart is more simple when it comes to wiring (no OBC) and series carts are workhorse cart. They handle slow, creeping driving conditions (i.e. hunting and driving over unsteady, hilly terrain) without the motor/controller over heating. Series cart are not going to win and land speed records but (with the right motor/controller) try to climb a tree. The flip side to that is SepEx carts have more user adjustability and can produce faster speeds. Using alltrax software and loading different field maps for whatever motor you have can provide you with many different types of driving conditions. One field map can give your motor more speed and less torque while a different map can provide you with more torque and less speed. The options are vast. But regardless, there is always a trade off with the speed torque relationship. As for your wiring dilemma in regards to your lithium pack and you not wanting the use and HV/LV relays (why not? I use them with great success) why not try a sell the Chargery charger you have and invest in ZEVA components and use the TC Charger to communicate with the BMS via CanBUS? Everything from cell management to charging voltages will be controlled at the touch of a monitor screen. |

Re: 92 CC DS gas, convert to lithium electric rebuild thread
Just realized you already got the MOT-A4 from Dave so it looks like you're already invested in going SepEx. Maybe Series can be for your next cart build
Dave will not steer you in the wrong direction so I would go with whatever he's suggesting |

Re: 92 CC DS gas, convert to lithium electric rebuild thread
While the thicker wire of the primitive Series motor will withstand heat better when overloaded, I think a properly configured Sepex cart with a torque motor and powerful controller has much better control of torque delivery and offer superior low speed handling.
The OBC is also present in all Club Cars 48v Series carts. The BMS LV and HV controls are on a cell level, the Controller can only handle pack level which is worthless for lithium safety. |

All good NCPW! Your previous post is good information, I like learning about all of this stuff as I go!

With what you are saying about the BMS and the controller. Between the two, would not they protect in the event of LV/HV scenarios? To be clear, I am at best a novice when it comes to electrical. That is probably abundantly clear, by my questions... I do realize there has to be a reason to add in the additional LV/HV relays, otherwise folks would not bother to do so. I just don't truly understand the need to do so... |

Re: 92 CC DS gas, convert to lithium electric rebuild thread
You do not "need" an OBC with any cart if you are using a smart charger. The OBC was only for controlling the charger (Powerdrive) in the older club cars. They have been gone sinve mid-'14 and were replaced with ERIC chargers (HF style) Most will replace the old Powerdrive's with smart chargers when there OBC's fail.

Re: 92 CC DS gas, convert to lithium electric rebuild thread
While I do some more research on the recent wiring questions...
I am told I can use the keyswitch that came on the cart. How does one figure out which of the two posts to use, since it has 4? I am not going to be using a backup buzzer or the factory battery warning light, so from what I can tell just need to use the green and blue wire from the wiring harness. However, I don't know which goes to which post... |
