My aging pack is losing capacity as it gets colder here. I have no room for insulation techniques. Is there anything to gain by keeping current running thru the pack constantly to keep the batteries warm??

Gary,
I am thinking that a better solution might be to install a battery heating
system. We did this in one of our race cars in order to raise the temp to 98
degrees prior to racing. It helped tremendously! The method that we chose
was with a water bed heating set up, as it is already designed to maintain
85-110 degrees with a low current draw.
Best of luck!

You can heat them with charging current; but it will increase water
usage, and further shortens the remaining life of the batteries.

You're on the right track in adding insulation. That will trap the heat
naturally produced by driving and charging. I've found that about 1" of
styrafoam on all sides is sufficient if you drive and charge every day.

If you don't have room for this much insulation or don't drive daily,
then a battery heater is a good alternative. With insulation, it doesn't
really take all that much heat. 10-20 watts per battery is probably
sufficient.
