Thank you for choosing FlexCell to help your patient better
power their prosthesis. Whether you’re retrotting FlexCell
into your patient’s existing prosthesis or you’re building a new
prosthesis from the ground up, this guide will introduce you to
FlexCell and help you install the system.
The installation of FlexCell should be performed exclusively
by a licensed prosthetist or technician. Any unauthorized
handling or installation of FlexCell will void the warranty. If
you have any questions or are aware of issues related to

MEET FLEXCELL
The FlexCell system is intended to power upper-limb prosthetic
devices. The system consists of a charging port with an
on/off button, a charger, and flexible lithium-polymer gel
batteries. The flexibility of the batteries allow practitioners to
conform them to the inner surface of the prosthesis shell.
The battery system is modular to accommodate various
prosthesis setups. Up to four FlexCells can be combined for a
maximum capacity of 2200 mAh using FlexCells or 1320 mAh
for FlexCell Minis.

1.1 Specications
FlexCell is compatible with most terminal devices.
FlexCell is available with three types of output connectors and
has been tested with several prosthetic terminal devices such
as hands, wrists, and elbow units. However, always conrm that
your terminal device is compatible with FlexCell’s specications.
If you have any questions regarding compatibility, please
contact Innite Biomedical Technologies.

Pictured above is the to-scale maximum bend radius for the
long axis of a FlexCell battery. The maximum bend curvature of
the FlexCell cannot exceed the curvature depicted above.

LongAxis
The FlexCell 550 mAh battery is not intended to bend around
the short axis; doing so can damage the battery and void the
warranty. Bend 550 mAh batteries around the long axis only.

2.3 How to Install FlexCell
A. If the charging port will be mounted on the
prosthesis surface, place the provided flange in the
desired location when molding the shell to create an
accurate opening.

15
2.3 How to Install FlexCell
B. Place the FlexCell batteries anywhere within the
prosthesis shell, taking care to ensure the batteries
are not compressed and will never be in contact with
the user’s skin. Adhesives can be used to secure the
batteries to the shell’s inner surface.

16
C. Slip the junction box into the prosthesis and connect each
battery to the junction box on the controller. The connectors
are designed to plug in only one way. Check the orientation if it
does not plug in easily.

D. Connect the output connector to the terminal device. Pay
close attention to the polarity of the connector depicted below.
Only use FlexCell batteries with the FlexCell charging
port and junction box

17
E. Insert the charging port into the flange. It is designed to only
insert one way and should snap in easily. Check the orientation
if it does not insert easily.
