WARRANTY INFORMATION
We strive to make sure our items are accurately described so that people are clearly
aware in advance of what they are getting, and anyone who has any doubts or
questions we ask that you please contact us before placing an order. Nevertheless, it
happens often enough that goods need to get sent back here whether for refund,
exchange, or warranty.
Warranty covers items that fail when used within their normal operating parameters.
One Year Limited Warranty Battery/Charger
Batteries and battery chargers have traditionally been our largest source of warranty
support. Right now, we are trying to tackle this and are only selling quality lithium
packs developed in partnership with Samsung or sinlion. The battery and charger
warranty is 1 year, and it would cover things like:
Faulty BMS circuits that trips below rated current or cause premature pack
cutout
Pack that delivers less than 80% of its nominal capacity at a 1C discharge rate
Internal cell tab weld coming loose
Warranty does not cover:
Lithium batteries that have self discharged below 2V/cell from being left on the
shelf for an extended period of time
Water damage, which does not affect the cells but can lead to unreliable BMS
circuit behavior
Lithium batteries are liable to self-discharge over time because the BMS circuit
itself draws current from the battery pack. Although the amount of current is
usually small ( < 1mA typically) it is still enough to kill a battery in 1-2 months if
it is stored in an initially flat state. If you plan to store a lithium battery, be sure to
top it up with a charger at least once two months.
Often, we get issues that are wiring related, such as a fuse holder that starts to melt
from being loose, or a connector that gets corroded. In these instances, we will send
or replace just the wiring part.
One Year Limited Warranty Motor/Controller
This warranty covers material and manufacturing defects in the motor and controller
itself, and not issues related to installation. For instance, the following items would
not be covered by our motor warranty:
Problems resulting from Axle Spin-out
Examples of things that it would cover by motor warranty:
Damaged sensors or gears in hub motor
Damaged freewheel mechanism
