Hi All,
I am considering doing an LTO upgrade experiment with my old depleted 24kwh leaf battery.
Was looking at the Yinlong 40A cells.
Dala (https://github.com/dalathegreat/Nissan-Leaf-Bruteforce-Upgrade/) recommends against changing cell chemistries for these reasons:-
1. Range estimation/charge bars/GOM:
2. battery management system will not behave correctly:
3. Isolation resistance error:
4. Fast charging issues:
But nothing that seems insurmountable. I would really like to just buy a hundred of these LTO's, bang them in and see what happens.
Assuming that they have similar absorption and discharge characteristics and I can connect them the correct way, and find a micro-BMS solution, and achieve correct voltage range etc. are there any other reasons for not going ahead with this project that are showstoppers?
I mean why aren't LTO batteries mainstream? Is it just a cost thing?
Thanks,
Oliver
