Are you 100% sure, i don't think the M4's or any BMW (maybe an i8) uses an Li-Ion battery. Open the hood look at the battery if you see liquid in the cells it's not a Li-ion. If it was a true LiPo it would super expensive and the charging circuitry very sophisticated indeed. Perhaps it's its an advanced glass mat battery or AGM (not a LiPO) good battery over conventional wet cell and you still need a very good charger as not to ruin the battery which is easy thing to do.
