48 in-lb is the spec for the Prius 5mm terminal nuts. The Civic bolts are 6mm, so I would go 58 in-lb (based on 6/5 * 48).

It's more about contact pressure than traditional bolt pre-load. My estimate is near the high end for low grade 6mm threads on:

that makes sense, new problem: the screws are torqueing the ptc strips. Short of bracing them with a small screw driver,any suggestions?

EDIT: eh, it was only a handful which concerned me, just to get it as snug as it was I'd deforming some a little

A little is normal. Those screws don't need to be more than '"snug." Once they start to twist, you're likely done.

This is concerning... I really thought that other idiot who had the car before me just grid charged and called it a day...
I got like a pink set of sticks on one side and orange on the other in pack A

before i thought it was a heat shield or something obscuring the view of the sticks.
I got volt taps all over mostly 13+/-2. And one at 8.

Considering just disassemble this and checking resting volts to find the obvious dead one and load test the ones sitting at 7+
other pack sat a month after grid, this one probably sat a month in car unused.

Where's the fan? In the rear deck? I thought it would be mounted to the batt pack

Both of those look "orangish" to me.

Orange sticks were originally used in the Insights and are generally accepted to have higher internal resistance by design when compared to the typical yellow HCH1 sticks. I have seen them mixed and matched on several occasions.

There are translucent plastic tubes over the 3 sticks at the top of the pack when installed. They may make orange look pink.

You're about to see another of those occasions.

The second photo sticks looks rose colored IRL. What color does king Kong use?

When facing the IPU (intelligent power unit - the entire "bay" containing the battery and electronics behind the rear seat) the blower is behind the electronics on the passenger side.


The blower "exhausts" into the ducting in the trunk and creates a vacuum in the IPU bay. This causes air to be drawn in from the inlet. The seal of the IPU cover is important for this reason.
