Prius HV battery replacement

As title states
Began with testing of new NiMh cells 28 total.
Removed battery from trunk a bit heavy/bulky to handle alone (somehow a weakling like myself managed).

Cleaned busbars and reinstalled into plastic holder.
Cleaned hybrid cooling fan blower wheel + housing.
Uninstalled old NiMh modules, reused frame for new modules. Torqued end plates
Torqued battery to case hold down bolts

Reassembled everything else.
Reinstallation was a pain. My back has disowned me.
Ran Dr.Prius life expectancy test 103%

Average km/l before replacement was 18.5 (over 2500 kms)
Km/l after replacement 26.5 this is 62mpg (this is only over one trip though normal driving no maximum efficiency techniques employed).

Where u sourced the new cells from?
As well, what's the operating voltage of that battery?

Cells sourced new from China.
Operating voltage is 28 x 8= 224V

You just order how many cells you needed and shipped by ocean?

In a nutshell yes
Not by ocean... Air freight UPS
