Lithium NanoPhosphate

[Tubamanandy]

Would I be correct in thinking that Lithium NanoPhosphate is the best lithium battery technology currently available (possibly manufactured by A123 Systems) ?

Best for what?
These are the parameters that I'd consider:

1. Cost
2. Continuous discharge rate
3. WH per kg
4. WH per litre
5. Safety
6. No of charge cycles (life)

They score well on 2, 5 and 6, but poorly on 1 and 3.

I'd consider that Panasonic NCR18650PF are superior. They're half the weight and still score well on all the other five parameters.

Best technology currently available - I guess wont be the best for cost but maybe best discharge rate/charge cycles & Continuous discharge rate

Apologies, missed the bottom of your reply - where would you get a battery pack eg. 36V 16Ah made up of those Panasonic cells ?

The 36v 11.6aH batteries have 40 of them. They're quite easy to find on Aliexpress. 50 cells would be 14.5aH. You can try searching Aliexpress. I know Xofo do one with equivalent Samsung cells, and so does EM3ev:
