I also have the Braille. Works great.

Voltphreaks you need to make a bracket to hold it in place and you need to be careful if you live in a place where winter is cold because I have heard issues with the Voltphreak. Certainly one of the lighter lithium batteries on the market and very well made

All lithium batteries will have issues in cold. Solution is younturn on headlights to warm the battery before starting. Porsche has a notice about cold performance with theirs.

I have a LiteBlox in my GT4

Works well, no problems, no reprogramming necessary.

That seems like a great alternative than braille. Question - when installing where there any modifications required to keep the battery in place? Or just a straight swap? Also what sort of trickle charger do you need for that battery? Thanks!

LiteBlox offers a very nice Carbon Fiber plate to directly mount their battery on 981/991 platforms.....they only problem is that for all of us on this side of the pond we can't get the product.
