I have wanted to add more cells to my main pack for a while. In fact my camper set was originally bought to be in the main pack, plus one more, making it to 50 cells.
With the pack getting to the point were range was borderline reaching 80km, I have now made the effort to add the extra cells.
With current situation and thinking decided to use these 5 plus 3 more, making it up to 52 cells now in the pack. These 8 new ones are LYP and the old ones are LFP chemistry. The Zivan chargers have the output voltage adjusted to suit the new pack voltage. For balancing, I did not have any more Relativities, so single cell (3.7v) chargers are used. All small chargers are switched on by the end of the Zivan charge. These 8 new cells are also monitored on the same monitoring screen as the others. Performance and range has been increased.
Relativities testing has proved reliable. They are still working.
So far have driven on these batteries, 419582 - fitted with speedo reading 350153 = 69429km.
That makes it $16200 / 69429 = $0.23 cents per km.
There is still more power in them yet.
