Six

(up

Limited
Warranty
for
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 6 months, and it would cover things like:
Faulty BMS circuits that trips below rated current or cause premature pack
cutout
Loose Internal cell tab soldering
Warranty does not cover:
Lithium batteries that have self-discharged 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 every month.
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
(up
to
8000km)
