No worries.
Both L1 and L2 are very slow charges. Any difference in battery life between the two will likely be undetectable.
The service manual confirms the layout of the battery - two cells in parallel, and 96 in series. If each cell is 33Ah as on AESC's EV cell page, then two in parallel is a 66Ah 'cell'. Even low quality cells can handle routine charges at the 1-hour rate (1C). The 1 hour rate on our 66Ah cell is 66A. (I actually think the cells are larger - so 66A is likely a worst case example.)
Level 1 charging is 12A at 120V - 1440W. 1440W into a nominal 350V pack is 4A.
Level 2 charging is 16A at 240V - 3840W, but the charger is 3300W. 3300W into a nominal 350V pack is 9A.
Please note that 4A and 9A are SIGNIFICANTLY lower than the 66A 1C/1hour charge rate.
Yes - L1 and L2 are very, very, very easy on the pack.
Enjoy!
