My Sharkshield is working again! Thanks Lucky13!

Thanks to Lucky13s article and instructions!  My battery went out on the Sharkshield and the company wants a lot of money to swap units for just a bad battery. I was going to build a pack but lucked out and Lucky13 still had a pack he had built. 

My case is the earliest version of the Freedom so I had to
modify my case differently. I cut the plastic circuit board slot and had to trim the side supports narrower and all the way to the bottom of the case to allow the unit to slide back together. The battery is a bit larger and flexes the circuit board slightly.  No problem as it will have a bit more capacity than the old battery pack.

I turned it on and got a green light and it began to flash!   I went ahead and ran a thin bead of silicone around the seam just because. Likely overkill but it will add a bit more protection and is easy to remove if needed.

That's great. I'm glad you got it to fit. I will update my old thread with your mod info. Hopefully the next guy knows exactly what to do with the model "A" mod.
I sourced some batteries that are the supposed to have the exact same dimensions as the original model "A" "B" packs. Will test them out when they arrive in 8 weeks. If those work out well, then this could be a truly drop-in replacement.

Feel free to let me know if you have any issue or comment about the battery pack.
