E-bike battery cases for long-distance touring
Touring is a capacity problem before it is anything else, and the format that carries the most cells is not the one most builders reach for.
Who this is for: Pack builders supplying touring and audax frames, and riders speccing their own range build.
What this build actually constrains
Capacity first
Range comes from cells. Everything else is secondary until you have enough of them.
Removability matters more than usual
You will be charging in places that are not your workshop. A pack that lifts off the bike is worth real money.
Weather is not optional
Touring means rain. A sealed housing is a requirement, not an upgrade.
What we would put on this build
- ['
- Silver Fish — 27 models, up to 130 cells on 18650 and 160 on 21700. ', '
- Rear Rack — 17 models, up to 104 cells on 18650 and 78 on 21700. ', '
- Downtube — 21 models, up to 200 cells on 18650 and 160 on 21700. ']
Water Bottle
If the target is range, a bottle-boss case is the wrong end of the range. Above roughly 52 cells the format stops supporting the requirement and a downtube or rack case serves you better.
Models worth starting from
Full range in every format, with the numbers, in the format comparison.
Questions we get about this build
How many cells do I need for a 100 km e-bike range?
Can I carry a second battery on a touring bike?
Send us the build and we will say which format works
Frame envelope, cell type, series and parallel count is all we need. If the answer is that none of our moulds fit and it needs a new one, we will say that rather than sell you the nearest thing.
