Shimano Dura-Ace Di2 7970 EW-7975 Modified Internal Wiring Seat Post Battery Kit
I have modify a new EW 7975 harness for a battery in the seat post to get rid that the ugly Di2 battery on the frame. If you’re building a new Di2 bike this is a clean way to finish off the build.

This modified version can be custom build to any buyers special. Special hard to fit frames like some Look, Cervelo, Felt. And any custom frame… Just tell me what length for any section and I’ll make it. DOES NOT REQUIRE YOU TO REMOVE THE SEAT POST TO RECHARGE THE BATTERY! It charges through the harness via. FD/RD(4pin) harness plug, it can also charge any standard Shimano battery without removing the battery, so if you have another bike with the standard Di2 battery you can charge with this charger as well. If you are looking for Ultegra see my other listing. New size battery is a smaller round battery 800mah, will last 5-7 months on one charge 40 grams, 0.748″ (19mm) diameter x 3.6 ” battery can be placed anywhere in the frame, seat tube, down tube, doesn’t matter where you place the battery since it does not need to be removed to charge.

Light is red: in charging. DC 8.4V 500mA Max. This battery will fit in all 26.8 seat post AND LARGER. If you can fit a AA battery in your post with a little wiggle room, than this battery will fit. I also do custom installs on non Di2 specific frames using a complete internal harness, if you need my service just ask. If you need a complete internal harness with this option, with the battery in the seat post (see my other listing). I have an option for just the battery in the seat post if you already have a bike with an internal harness (see my other listing for just the cable). Note: wire and connector color varies, depending on what I have in stock. To install the battery. Apply electrical tape around the battery so it fits snug inside your seat post (see pictures). Push it in I provided zip-tie around the battery for removal see pic. Plug the battery connector into the seat tube cable coming out the top of the seat tube in the frame. Put the seat post back in the bike, and your ready to ride. Seat post not included. Battery can only be charged through the harness! Your kit will arrive soon and the battery is fully charged, but some time next year it will need to be recharged please follow these instructions, and always remember to unplug both front and rear derailleurs when charging just to be safe. Plug the charger plug into the front junction plug of the harness if your charger plug has 5 pins, if it has 4 pins it plugs into the rear derailleur. Your kit will arrive soon and the battery is fully charged, but some time next year it will need to be recharged please follow these instructions, for EU buyers due to the unstable 240ac power systems. Always remember to unplug both front and rear derailleurs, or use a surge protector when charging just to be safe. The light on the charger will be red when charging, green when charged, 60-90 minutes. To check the battery level. Press and hold either shifting switch for 0.5 seconds or more. You can check the amount of battery charge remaining using the. Battery indicator on top of junction (A). 100 % Illuminates green (for 2 seconds). 50 % Flashes green (5 times). 25 % Illuminates red (for 2 seconds). 0 % Flashes red (5 times). When the battery charge is low, first the front derailleur will stop operating, and then the rear derailleur will. When the battery is fully spent, the derailleurs will stop at the positions where they were last. If the battery indicator is illuminated red, it is recommended that you recharge the battery as. As is the case with ALL Lithium-ion rechargeable batteries running them completely dead can damage the battery, including the OEM Shimano battery. If this happens it may not be possible to charge the battery without removing it, and although it MAY be possible to revived the the battery, the cells may still be damaged, and the battery may run dead in a matter of days… So it is your responsibility to check your battery and recharge it before it goes completely dead.
