EZGO TxT48 with Leaf Modules
Well, i have decided to document my EZGO Lithium transformation build log here. I have gone back and forth between Leaf, Volt, i3 BMW battery packs but I have settled on the Leaf 7 Module 14s configuration w/ the Zeva BMS. Mainly because I am fortunate to be in the same area as PingEye3 who has a great build pattern with the Leaf already and plan to leverage from him what he has built before to the best of my abilities. He has a very clean setup. Thanks PingEye3 for your help, time and information.
I would also like to give a shout out to MCJEFE for his build thread. I plan to copy as best I can from that thread. You have done a great job documenting your conversion for others to follow and build upon. I would also like to give a shout out to cmysstailights for the terminal cover design and 3D print. |

Re: EZGO TxT48 with Leaf Modules
This is where she has been. Torn down to the frame and built back up with a new body and she looks much better today.
The batteries have seen better days so Lithium conversion is on. |

Re: EZGO TxT48 with Leaf Modules
I plan to reuse my lead acid charger. I found some drawings of a similar Chinese charger board and found that the three pots adjust output voltage, current, and current cutoff thresholds. I played around with the Pots until I found the output voltage adjustment that sets the voltage adjustment for the Bulk and Absorb phases.
Note - Need to be careful with these adjustments as this board only can take 360Watts (written on board as DL-360W). I have the voltage currently at 52V for the FLA batteries and I will increase this voltage to 58V when I am done with the battery replacement for the lithium batteries. If you increase the voltage you will need to decrease the current to stay under the power threshold of the components on the board. This charger will give me about 6amps during the Bulk phase and I will be under the 360Watt Max still. The Absorb phase will transition to the float phase once the current drops to around 5%. This can be adjusted but I don't plan to change this setting from the default in the charger. |

Re: EZGO TxT48 with Leaf Modules
Check settings, my charge voltage is not 58v. Had to lower it so the cells would balance

Re: EZGO TxT48 with Leaf Modules
I'm a little confused. Nothing new with that but in your BOM links you show 2 10' pieces of 2 gauge cable (1 black and 1 red) and then I see a link for 1 20' piece of 2 gauge red cable. The first is listed in your BOM list but the second isn't. Unless I'm just missing something.
Just wondering what the 20" piece of red is for? Also, many of the links in your BOM are not working! Thanks! Brad |
