There is no trouble at all.
Now this question may be harmful to your health.
1. You will need to understand the resistant of your coil and how much the battery current is able to supply.
2. You will also need to understand that over-discharge will destroy your battery and possible vent/explode on you.
I would suggest you read up on battery safety before considering Mech-MOD.
One way to do would be use a MECH-MOD + KICK = SAFE!!!
So, in short :
HanaMOD + any reasonable battery = SAFE.
MECH-MOD + KICK + good battery = SAFE.
