I wouldn't want to commute that far by ebike, but if I had to, here's what I'd buy.

I'd then put 20-25ah of rc lipo on it and have a charge station at work and home. About $400-$500 for batteries. Or you could go with a 20ah lifepo4 pack and a second charger, but it's going to be big and heavy. Or you could go with 20ah of NMC, but that's going to really cost you and you will not get any more life from it compared to rc lipo. While I don't like bms's, it would make charging easier, so you might want to use one with the rc lipo. Personally, I'd just bulk charge with a timer at one location and balance charge at the other.
