EZGO 2Five Lithium Conversion
I have a 2014 EZGO 2Five (4 x 12 volt configuration) and am interested in converting it to one of the Nissan Leaf based battery packs sold by EV Battery Center.com (http://evbatterycenter.com/HAC4/inde...-15&Itemid=605). The battery pack has a power output cable included with SB175 Andersen Connector and a charger output cable with 50A Anderson connector.
They sell an optional 4 AWG, red/black, 2 ft cable with 175A Anderson (red) to connect from battery to the solenoid and a 12 AWG cable with Anderson connector (grey) 5ft. is included with the on-board charger. I have read multiple other forums regarding lithium conversions, but was hoping to get some specific questions answered: 1. Has anyone completed a 2Five conversion? If so, can you please provide as much detail and photos as possible? 2. The manual states that the cart has a 48V on board battery charger with DC to DC converter. Is the DC to DC converter built in to the on board charger, or is it a separate module that I can continue to use after replacing the existing charger with an on board lithium ion charger? 3. How exactly would the wiring work? I currently have three sets of wires attached to a positive battery terminal and three wires attached to a different negative battery terminal in the series. I want to ensure that I wire the new pack safely and correctly, so all of my accessories continue to work properly. Any insight would be appreciated, and please include as much detail as possible. I can provide pictures of the existing connections if helpful. Thanks. |

There's no reason that you could not convert to lithium, but keep in mind that you should not store or charge LiPo packs in your garage. There have been too many incidents of LiPo packs catching fire or exploding lately. This is why they are now warning people to charge them outdoors and away from structures. Bob |

I was asked to supply my battery charging technology to Tesla in 2013. While it would have been a very nice contract, I wanted no part of that liability. Bob |

Re: EZGO 2Five Lithium Conversion
Bob,
I noticed that you did not mention all the fires caused by the Nissan Leaf cells that have been all over the news. Oh Yeah, there aren't any. Check out this test trying to burn a Nissan Leaf cell. Done by the Hybrid Auto Center in Las Vegas. https://www.youtube.com/watch?v=Jz37WycW-7E |

Re: EZGO 2Five Lithium Conversion
You can contact "fullriver battey" in CA. They are a authoized Delta-q distributor. And they can make you a profile for lithiums for your current charger. You could sent it to them for this servic and use the charger you have now, with it's built-in dc convertor.

I am not sure where I would connect the other two wires that are connected to the positive and negative posts on my existing batteries since the lithium battery pack only has a SB175 Andersen Connector? |

Can you post a link to the ANN/ANL fuse holder you used and let me know what size amp fuses you used? Also, it looks like you have two wires running from the cart to both the "+" and "-" studs on your two fuse holders. Where are the second wires coming from? Are those the DVM and reed switch bypass wires you were referring to? If so, are you connecting the reed switch bypass wires to both the "+" and "-" fuse studs? Is the DVM you are referring to a digital volt meter and are you connecting it to the "+" and "-" fuse studs as well? If I replicate your setup, can I then attach all three cables that are currently attached to the "+" post of my existing battery series to the "+" post on the fuse holder and all three cables that are currently attached to the "-" post of my existing battery series to the "+" post on the other fuse holder? |
