I recently bought a BH E-Motion Diamond with a 12Ah battery. It was supposed to come with a 13.5Ah battery but after waiting several weeks the dealer was unable to supply it and offered the 12Ah battery instead at a small discount.
I live in a very hilly area and normal commute to work is about 24 miles with about 600m of ascent. On medium power assist, one return trip is almost completely draining the battery. I've done the trip a number of times now though, and it does always seem to last the trip.
The real problem is going to come in September when I have to get to uni, which is a 29 mile round trip with 730m of ascent. I'm planning a trial run in the next few days but frankly I don't think it's going to make it. This is very disappointing because this was one of my basic requirements when I bought the bike.
Do I:
1. Buy an 8Ah battery and take it with me to swap in when the big battery dies. I guess this would work, but it's additional weight and loss of carrying capacity.
2. Find a bigger battery than 12Ah and return the 12Ah battery to the dealer. I don't know if a suitable battery even exists though.
3. Something I haven't thought of. I'm open to suggestions.
