The Lithium-Polymer 540i
Conversion Kit is no longer available.
click on the links below to download the instruction manual for
the Lithium-Polymer 540i Conversion Kit. You will need Adobe Acrobat Reader
for viewing. Please note: this kit has
a 27-turn motor limit and should not be used with any 540 motor
with fewer than 27 turns.
The 540i conversion kit accommodates many different
types of lithium-polymer batteries which are available from a
wide variety of online retailers. Click on the link below to
download the latest spreadsheet of many suitable battery packs for
this kit. This list is being updated as often as new
information becomes available to please check back here often and
always make sure you have the latest spreadsheet.

Here's a few places you can buy Lithium-Polymer
battery packs for the 540i conversion kit:
These templates can be printed out on your printer
at home and used as a reference to determine which lithium-polymer
packs will fit into the 540i conversion kit. There are two
factors which affect how big the pack can be: the size of the
servo (micro, mini, or standard) and whether or not that pack will
fit through the belt, or sit to the side of it.
Download both templates and see which one works best for you.
We do not recommend anyone attempt to build their
own battery pack out of single lithium-polymer cells. Always
purchase pre-made battery packs from retailers who specialize in
doing so. Please follow all of the manufacturer's
recommended usage guidelines for li-po cells. You are
responsible for understanding how to care for and maintain your
lithium-polymer battery packs. There are a lot of great
tutorials and guidelines available online (see Recommended
Batteries above) and we recommend you
read them and study them so that you completely understand how to
charge li-po packs, how to use them, and how to care for them
Everybody knows that it's not just about how much power you have
but how much weight that power has to push around. All of
the x3 series conversion kits are much lighter than any typical
1/10 scale car/truck, so the power-to-weight ratio with a whopping
540 motor, regardless of turn, is very high for all these kits. Ultimately it comes down to what you think will be the best setup
a simple spreadsheet that uses Excel to calculate predicted speeds
given certain criteria such as motor RPM, number of cells, tire
diameter, drag, etc. A must-have tool for any hobbyist.
