Cool deal! I want to see pics when it's done!
I checked the battery just now and it's at 173.9 volts. I'll give it a couple of hours to see if it changes any, but it's been on the charger almost 24 hours now.

There is no point going over 24 hours unless you have a 8aH battery. ~350MaH x 24 = ~6500 after taking into account charging inefficiencies.

How do you even tell what battery you have? Mine doesn't have a name on it or anything to identify it as far as I can tell. It might be the original battery for all I know.
But if the voltage keep increasing, should I just let it run?

It's now at 174.1, so it's definitely still charging. Luckily I'm off all week, so I can leave it sit today and see where it tops out.

After 24 hours I'd let it rest, and grid charge it again in a few days, just to be safe. If the voltage is still rising it almost certainly means you're still charging some cells though.

Since you have the clutch switch you could do a poor man's discharge cycle if you wanted to. Charge for 24hr, then run the car around using max assist but don't allow the car to regen, and take the battery all the way down to 1/20 bars, then recharge again. Not sure how effective vs a real discharge but yea. I know discharging makes a difference, I sure noticed improved battery life when I did my charge/discharge cycle (I have an actual discharge kit though).

Will the grid charge still even out the cells if it doesn't fully charge the battery?

Yeah, they should be more level. You might still have some cells that are lower than others, if voltage is still rising, but they should all be much closer now.
I vote to let it rest for a day before running it down.
EDIT: I dunno if max voltage is a good indicator of a battery's capacity, but if it is and you're peaking 2-4v higher than mine, you'll probably be good for a solid 5+ minutes of full assist before running it down, once it's balanced.

Somebody over at IC said it's charging to a higher voltage because my pack is a little weak, and that yours topping out at 170 is a sign of a really good battery.
I guess I'm going to pull mine off the charger, I don't know that going any higher will help anything.
I also bought a battery tender for the 12V battery that I'm going to install today once it warms up a bit (after me any my son go kayaking anyway)

Well, as I understand it the voltage will stop rising once the cells are full. If it's still rising, not all of your cells have reached peak and it's not completely balanced yet.
