Nissan Leaf battery Cell test data

I have carried out capacity tests for two types of Nissan leaf modules.

24KWH pack module (500WH Module):

The module contains 4 cells (33AH each), 2S2P configuration. This test data is from 2 of the P cells.
From 4.19V to 3.00V @ 20A

Despite multiple cycles, all I could get was 47.39 AH out of 2P Cells. These packs have approx 800 cycles on them.

the 2018 Leaf comes with a 39,46 KWH Pack. Each module is now 8 Cells (56AH each) 2S2P X 2 (essentially 2 of the old modules combined)

39.46KWH pack module (1670 WH Module):

From 4.18 to 3.00V @ 20A

The best I could get out of these is 105.7AH out of 2P Cells. These packs are essentially new.

Very impressive! Nearly 2.5 times the capacity in the same space. The voltage sag seems to be a bit better too.

These new packs will go into the Fazer and should give it a 85+ Mile range.

Battery Swap

Did some work today. All batteries and the battery frame are out of the bike.

I also mocked up the newer modules in the frame. There are a few small issues with the old frame (wateproofing and some screws pointing into cells!) but otherwise all good, so I am going to extend the old frame upwards and build a new lid etc.

The old cells are all being balanced, ready to go in the Vectrix VX-1.

Yamaha Fazer Electric conversion

Hi all.

Just some details of my FZS600. I bought it pre-converted, so I did not build myself, but I have already started a few modifications.

The specs are (currently):

Enertrac 602 hub motor

Kelly KLS 8080i 400A peak controller

On board 4KW fast charge (Huwaei supplies)

13 Leaf modules (60ah capacity, drained to 45ah), they seem to only have 45 ah max cap when charged to 4.15 volts, so I assume they are quite old.

I am in the process of swapping out the 13 leaf modules for 7 40KWH leaf modules (newer gen). This will bump the system voltage up 8v or so, which should give a few more MPH top speed, whilst also nearly doubling the range!

The old leaf cells will be paired up with 6 more “24kwh pack” modules to then go in my vectrix VX-1 (which I will post about shortly)

Some pics of the build:
