Be *very* careful when doing this and do not leave the battery unattended.
i had two 2s lipo with under 6V, and when tried to charge thse i got error low voltage. So i detached the balance adapter, charged it a little using lipo mode with 1.6A i think (hope it will not die) and then all went smoothly. After charging i discharged it and charged again with balance adapter connected.
