ESR Models FAQ
|
| When I ride my ESR
and the light goes to yellow, why does it go back to green if I turn it
back on later? |
The batteries are
chemical in nature, the light is based on voltage, and the chemistry can
make more voltage available over time if you stop depleting the
batteries and give the chemistry time to recover. Although the voltage
rises, the actual capacity of the battery does not and you'll find it
will return to yellow a lot faster the next time around. |
| Should I only
charge my battery when the indicator goes to red? |
No, if it's not
moving, the charger should be plugged in. If you've ridden it very hard,
you may wish to wait a while for the batteries to cool before charging,
but at the low charge rates that the ESR's charger can provide, we
really don't see this as much of a problem. Just plug it in whenever
it's not moving. |
| What happens if I
charge my battery when it's still green? |
It safely
recharges the capacity that it lost when it was ridden. |
| Does it hurt the
batteries to run when it's red? |
Both SLA and
Li-ion polymer battery life is longer if you don't fully deplete the
batteries before recharging. So, ideally, you should recharge it well
before you get to the red. That said, the "red" indication is
set at a threshold that is above the point of discharge where damage
should occur. So, letting it go red before you charge isn't such a
terrible thing, but recharging it in the green or yellow is better for
the batteries. |
| Does it hurt my
batteries when I go up a lot of hills? (I know it depletes the charge
much faster and that's understandable) But does it kill the battery
life? |
The more current
you pull from the batteries, the shorter the cycle life will be. The
more power you demand from the motor, the shorter the motor life will
be. That said, when climbing hills the recommendation is to get off and
walk if the ESR is laboring up a hill for more than 20-30 seconds. The
reason is brush and motor heat, as well as current drain from the
batteries. Think of it this way, would you rather walk 100ft up a hill,
or 2 miles on the flats with a dead battery? If a hill takes more than
30 seconds to climb, and you've got somewhere to go and you're not sure
if you'll make it there...walk the hill and extend your range. |
| How long should I
leave it plugged in after it starts blinking multi-blink (All three
lights blinking together) when using the on-board charger, or when the
red light turns green when using the off-board Li-ion battery charger? |
As long as you
like, but for safety concerns should there be an unanticipated failure
in the charger, controller or battery electronics, leaving the charger
plugged in beyond full battery charge for extended periods is not
recommended. Never use both on board and off board charger at the same
time. |
| Does it hurt the
batteries to leave it plugged in several days after it does the
multi-blink? |
No, but as stated
above, for safety concerns should there be an unanticipated failure in
the charger, controller or battery electronics, leaving the charger
plugged in beyond full battery charge for extended periods is not
recommended. Never use both on board and off board charger at the same
time. |
| Is it hard on the
chain/sprocket to coast down hills? |
No, but if you're
hearing abnormal noise coasting down hills you may have a tensioner,
chain, or sprocket problem. |
| What happens when
you ride in wet conditions? |
The same thing that happens if you drop your cell
phone in the pool. Scooter riding in the rain can be very unsafe, so the
ESR is not intended for wet conditions.
Some technically knowledgeable ESR riders who have a need to ride in the
rain have successfully water *proofed* the battery pan, motor and flux
capacitor.
