I would not consider that a BLS is the answer to your woes, but that's
just a general estimation. If you've not let the vehicle sit for long
periods with partial charge; if you've kept it charged after each trip,
sulfation is not likely to be a factor and the BLS is aimed at battery
de-sulfating.

Shorted cells will drag down the entire battery, especially under load.

Do you have a PakTrakr or CycleAnalyst installed? The first device is a
good way to see how your entire pack performs, both under load and under
charge. The second is an excellent device to help keep you from
over-discharging the pack. Over-discharging a pack can result in
substantially reduced range in a short time. The CycleAnalyst is a
top-notch "fuel-gauge" type device.

Do you have equalizers on the pack? PowerCheqs or BattEQs?

except under load when they stay within .4 volts.
