A little tip, that in some cases can prolong battery pack life
For some time, one of my packs have flattend out. It's the oldest pack I got, so it aint a surprice.
However, some of the problem was due to a 3/4-broken wire between the to saddles. The broken part was hidden under the isolation. Soldered in a new wire, and vupti, now the pack is practise worthy again.
