The cylindrical cells are complete and total garbage. I ran a brand new one for two years, and it performed very poorly. IR values had a huge spread, and it "surged" when under heavy accel. Voltage would oscillate wildly, and it was very evident that the car was varying current in response to the voltage swings. Pulled it and put a frankenpack in it (left over jumble of modules of wildly varying performance characteristics), and it ran WAY better than the cylindrical pack.

Consider what I mentioned above concerning HCH cylindrical cell packs being the worst ever. Now do the following:

1) Change from Sanyo cells to brand-x Chinese
2) Take a marginal cooling system (prius) and completely disable it due to changes induced by the new kit geometry.

How improved over Honda do you expect that will be (negative infinity)?

These "kits" exist because the Hondas are dying out by attrition, and they are looking for places to market their junk.

Any reconditioned option means:
Get a pack.
Have a pack failure every 2 weeks to 2 years.
Get another pack.
Rinse and repeat.

Without question the best consumer VALUE is a new Toyota battery. It's not even close.
Thanks for all this. Very helpful.

What about a battery pack that has all new cells, but the shell is refurbished.
