What to Look for in an Electric Skateboard Battery
When searching for an electric
skateboard battery, the first thing to decide is if you want a lithium ion
battery (Li-ion) or a lithium polymer battery (Lipo). A Li-ion battery is more
expensive, safer, and lasts longer. The Lipo is less expensive and doesn’t have
as much voltage, but is less safe and could catch on fire if misused. A Lipo
also needs the user to drain the battery when it’s being stored. That’s a lot
of maintenance.
The next thing to look for is the
number of volts and the number of ampere hours. Once you have that, all that’s
necessary is to multiply the two numbers together; this gives you the watt
hours. The watt hours will then tell you how long (in distance) the battery
will last until it needs to be charged. One watt hour equals ⅔ of a kilometer.
Decide how far you’d like your skateboard to travel on a single charge, and then
look for the power of battery you’ll need. It’s that simple.
Next, you should ensure your battery
is compatible with your motor. You want the voltage of the battery to be less
or equal to the voltage of your motor. You can shorten-out your motor very
easily if the number of volts in your battery are higher than the motor.
Finally, verify that whatever
enclosure you end up using is big enough for the battery you choose. You must secure
the battery inside the enclosure, but you don’t want it to be too tight. You
can make an enclosure yourself with a 3D printer or use a simple metal box that
can be mounted onto the undercarriage of the board.
