    Cell Make / Model & Specs

    All 21700 cells. Capacity below updates with your pick.

    Samsung 53G · 5.3Ah
    Range cell: lots of capacity, low current. Rated 10.6A continuous per cell (Samsung datasheet). Best for range, not hard launches.

    EVE 40P · 4.0Ah
    Built for high current: hard launches and climbs. Rated 35A continuous, 50A temperature-limited, per cell (EVE datasheet).

    Reliance RS50 · 5.0Ah
    High capacity and high current in one cell. Rated up to 70A continuous per cell (Reliance datasheet).

    Samsung 58E · 5.5Ah
    Range cell with a little more capacity than the 53G. Rated 10.7A continuous per cell (Samsung datasheet). Best for range, not hard launches.

    Workmanship (Cylindrical)

    What joins the cells together.

    Nickel strips. Our standard build, good for most daily riding.

    Copper strips. Lower resistance for high-current setups. Harder to build, so it costs more.

Description

Short on height inside your frame triangle? DogeTune TriHepta gives your 72V e-bike conversion a lower-profile battery option without reducing the cell count compared with our taller TriBolt design. Compare the outline with your frame, then choose the cells and connections for your build.

Less model height. The same cell count.

TriHepta’s seven-sided outline is the lower of our two triangle profiles. Both packs use 120 cells in a 20S6P layout, so the same cell selection gives the same nominal capacity. Choosing the lower shape does not mean stepping down to a smaller cell count.

The TriHepta CAD model is 39 mm lower than TriBolt, with the same model length and depth. That makes it a useful starting point when frame height is the constraint. Compare the full outline, including the sloped edges and the space occupied by any rear shock, before deciding.

CAD profileLengthHeightDepth
TriHepta373.71 mm204.85 mm88.45 mm
TriBolt373.71 mm243.85 mm88.45 mm

CAD model dimensions, including the visible external FR-4 wrap. Confirm finished-pack dimensions and mounting clearance before fitting.

Choose the cell option that suits your build.

The pack format stays at 72V; nominal capacity and price follow your cell choice. Use the configurator to compare the available cells and connection options. Share your controller details and intended use with us so the choice accounts for the complete setup, not just an Ah figure.

Show us the space you’re working with.

Send a side-on frame photo, measurements of the opening, and photos of your controller, charger label and plugs. Include shock and mounting positions and the cable-exit direction you need. We’ll help work through the fit before you order.
