Stilus Mk1 630w/h Bosch battery upgrade

[Ken]

Even after 3500 mls the 500 W/H battery hasn't let me down but recent leg problems have required more battery assist and thoughts of a 630 W/H are looming but can I justify the £650? Anybody else done the upgrade and comments appreciated.

The real cost is £650 minus whatever you sell the 500 WH for.
