instructions.
These instructions are fairly detailed for the benefit of those that want as much information as possible. I know that
some of you will skip reading and just get to installation. It would be beneficial to read the entire instruction sheet
including CAUTIONS at the bottom of this page before assembling or using your 857 or 891 sprint / escort 6+6.
A suitable battery will be required before you can use the this system. The battery case is designed to hold a pair of
custom LiFePO4 batteries supplied by Bioenno Power www.bioennopower.com battery part #

charger. For faster charging you could purchase a charger with each battery. The batteries should NOT be connected
together when charging. Use batteries in a Parallel circuit only when they both have an equal charge. Never connect
your batteries in a series (24 volt) for use with a 12V Amateur radio.
Purchase Correct Battery. Batteries and chargers are available Bioenno Power (links are provided on page 2 and at
www.portablezero.com) The
website unless you use the direct link or put the battery description in their search box.
Please read the section about battery use on page 2.
Although Bioenno Power has designed a battery for use with this sprint 6+6 system, you can choose any suitable battery
that meets the voltage requirement of your radio and will fit into the battery case. Battery case inner dimensions are
9.30" (236.22 mm) deep X 5.65" (143.51) wide X 1.71" (43.43 MM) tall.
Cautions:
Correct length (metric M4) mounting screws(included) must be used to mount the sprint and escort side
panels to the radio or damage to the radio circuit board can result. When using the Escort side rails only , use the
shorter M4 X 12MM for Yaesu Ft-857D and FT-891 The sprint battery case combined with escort side frames uses the
longer M4 X 14mm. Do not over tighten the mounting screws or the threads in the radio can become stripped. Adjust
your transmit power settings to operate within the current rating of your batteries. (check your operator's manual for
power setting adjustments. It is advisable but not mandatory that fuses (not included) be installed on both the positive
and negative power lead. The fuses can be located inside or outside the battery case. Care should be taken to make sure
any internal battery case wire connections are secure and insulated properly. Anderson Power Poles® are the
recommended connection technique. Make sure that you use a screwdriver that fits the 16 small battery case mounting
and cover screws properly. Don't over tighten the screws once they have seated.
