The Lithium Phosphate batteries even use your existing chargers.

This is correct. I bought a K2 w/o the BMS this year. I already owned a few Battery Tender Jr. chargers, so I emailed K2 and Battery Tender. Both replied the charger was fine for a K2. I was concerned about the lack of BMS and bought a K2 charger to conduct my own tests, so if anyone wants this $50 charger at a discount, let me know.
