Shorai LFX Lithium Battery for 2010 BMW F800GS

Lately I have been having trouble starting the F800GS in the cold weather like on the "Cold Weather Ride" with red and McMark. That day alone I thought I was going to be walking instead of riding. The problems that had me suspicious were the normal push the starter button and either get nothing or a slow listless start. After 3 days of being plugged into the battery tender there were no changes, it was then official the battery was dead. On Saturday I started my search for a new battery by calling all the local shops in town to find out nobody had anything other than the old style lead-acid battery. I was buying a new battery and wanted to try something "new". I figured since the majority of the shops were closed on Sunday and Monday, the order wouldn't get placed until Tuesday. I started my search online Saturday evening and found a couple of different non-lead-acid batteries that seemed to have more CCA, a longer life and wouldn't blow up next time I go tumbling over the handlebars. After all my studying I decided to get the Shorai LFX battery from a shop that delivers quickly and service is great.
I ordered the battery from Revzilla Monday morning at 8:00 am, the package arrived Tuesday at 5:00 pm. I know we are in the same time zone but WOW, great customer service, I guess they knew how much I wanted to be riding again. The package arrived and it felt like they forgot to put the battery in the box. The package was marked with arrows pointing upward but when the box was opened the inside Shorai box was laying flat along with the battery (try that with your lead-acid battery).

  • Shorai LFX21 A6-BS12

  • OEM battery weight: 7.9 lbs
  • LFX battery weight: 2.4 lbs.
Contents of package:
 
  • Shorai LFX Lithium Battery – LFX21A6-BS12
  • One set of terminal screws/nuts pre-attached to battery
  • Spare set terminal screws/nuts
  • Various sheets of high-density, adhesive backed foam sheets for LFX fitment to stock battery box if needed (do not throw away until after battery installation is complete).
  • Outer packaging with specs and dimensions
  • User guide
  • 5 Shorai decals, in three sizes







Directions:
  1. Remove necessary body work, seat and other parts to gain access to the battery.
  2.  Remove old lead-acid battery be sure to remove the NEGATIVE terminal bolts and cables 1st, then the POSITIVE to avoid the possibility of shorting from positive to grounded vehicle.
  3. Compare the 2 batteries side by side to notice if there is a difference in size. It is okay as long as the new LFX battery is slightly smaller.
  4. With the provided high-density, adhesive backed foam sheets, find the sizes that will make it similar in height and width.
  5. On the F800GS I needed to add approx. 5mm foam spacer. Peel the backing off the need high-density foam sheets and install inside the motorcycles battery box.
  6. Slide in new Shorai Battery.
  7. Attach mounting bracket to hold the battery in place.
  8. The LFX batteries can bolt cable eylets to either the top or the side.
  9. Be sure to install the POSITIVE terminal cable FIRST, then the Negative to avoid short circuits.
  10. Torque the terminal screws to 26 inch/pounds, Do not over-tighten.
  11. It is always recommended to use a #3 Phillips screwdriver so you can apply downward pressure on the terminal screws and to reduse torque on the terminals.
  12. It is recommended to use an anti-corrosion spray whenever the battery will be subject to water, especially salt water.
  13. Check that the Positive terminal of the LFX battery cannot short against any part of the motorcycle.
  14. If equipped re-install the terminal cover is re-installed before the battery box cover is fitted.
  15. Shorai LFX batteries are pre-charged to approximately 90% of capacity so it is not necessary to charge before usage. Generally one ride will fully charge the battery.
After install was complete I pushed the starter button and the F800GS fired right up. Perfect, I'm impressed with the initial power and the lightweight. This battery is awesome.

When I saw these at the Dealer Expo, I picked up the battery and asked how much they weighed full.

It's crazy how much they don't weigh.

Thanks for this. Getting one for the GF F800ST.

They really are impressive and Wheels hasn't had any issues with his that I know of.

I think the box it shipped in weighs more than the battery.

Did you attach the spacers to the battery box closest to the rider or closest to the front? I just got a Shorai LFX21A6-BS12 and am not sure where to put the spacers. I am also unsure of what the silver metal thing is in front of the battery (looks kind of like a radiator with wavy metal). Any idea what that is? I don't know if the foam spacers can touch that part or not.

I attached the spacer foam to the inside of the battery box. The only spacer I needed was for height and not width. The LFX21A6-BS12 is the same battery I installed and don't remember a silver metal thing besides the Shorai logo on the front. I would try to equally space the front and the back foam to keep the weight distribution even. I wouldn't think it matters what the foam it touching it is non-conductive.
