There is a safety by which the cover can't be removed unless the switch is off, but be extremely careful working with this pack.
Additionally, the activities at Insight Central are pretty much irrelevant to the HAH. No one is working on a Lithium pack for it. No one is offering enhanced control of the battery (MIMA, OBDIIC&C, etc.), and your options are to try and fix your pack or replace it with one filled with reconditioned Honda sticks or new Chinese sticks.
If you attempt to fix your pack via the typical reconditioning process described on the interwebz, you need to be okay with repeating it every 2 weeks to 3 months depending on the condition of the battery.
Grid charge/discharge is like a better solution. IF the battery can be improved by stick cycling, this will improve it. If it can't be improved, you've wasted far less of your life wasting your time.
Good luck

Saw this a couple months late!
I did notice the main terminals as live without the car turned on, and it surprised me! (Fortunately for me I noticed this by probing them with a multimeter -- not by shorting them!)
The owner of this car is a DIY car junkie. I built a grid charger harness for the IMA and I sold him a home-built grid charger of my own, since he said he wouldn't be driving the car frequently enough.
I already know stick-level cycling is a big waste of time as compared with pack-level charge and discharge. I don't even own anything I could cycle sticks with.
In fact I ended up NOT doing any kind of discharge on it because the taps weren't super out-of-whack even after letting it sit for a couple weeks. I jsut built a wire harness, charged it once, and that was it.
