RE: EQ10 batery usage?
This is normal, its impossible to match regulators close enough so that you get even battery usage. You would have to match them down to about 0.001 volts. You might want to consider a Wolverine switch. That will balance the battery usage before the regulators. You will still have one regulator doing 3/4 the work but your battery draw will be even between the two packs. Let me know if you have any other questions.
