72V 22AH E-Motorcycle Lithium Battery

A: About 60–75km of mixed urban riding at 40–55km/h, or 90–115km if you ride economically below 35km/h. Aggressive riding, hills or heavy loads bring it down to 40–50km. The pack holds 1,584Wh nominal, and e-motorcycles consume 30–45Wh per mile in mixed conditions.

A: Up to about 3,000W continuously. A 3,000W motor at 72V draws roughly 42A at full load against an 80A continuous rating, so there is nearly double the headroom the motor needs. For short bursts the BMS tolerates 90A ±9A for up to 15–25 seconds, which covers a 5,000W peak motor pulling about 70A. Most 22Ah packs in this size class publish only a 22A continuous rating.

A: 12kg ±0.5kg, which is the figure on our controlled specification sheet. The 180 INR18650-25F cells account for about 8.3kg and the remainder is the sealed case, the 80A protection board and the connectors. Heavier figures quoted for this capacity usually belong to packs with steel shells or a different cell count.

A: Two different measurements, both correct. 22Ah is the model designation, taken from nine parallel groups of 2,500mAh cells giving 22.5Ah at a 4.20V charge. 20Ah is the rated capacity actually measured at pack level, and the specification sheet guarantees a minimum of 19.5Ah. We publish both because a pack charged to 4.10V per cell holds less than the same cells charged to 4.20V, and that lower charge cut-off is what extends the pack's life.

A: Both are 20S packs and the difference is the cell and the parallel count. The 22Ah pack uses 9 parallel groups of INR18650-25F cells (20S9P); the 20.8Ah pack uses 8 parallel groups (20S8P). More parallel groups spread the current across more cells, which is why the 22Ah pack carries an 80A continuous rating and holds voltage better under load.

A: 20 cells in series set the 72V nominal voltage; 9 parallel groups spread the load across more cells. That 9P arrangement is exactly why this pack carries an 80A rating instead of 22A - at 80A each cell carries only about 8.9A. A 20S6P pack at the same current would load every cell at 13.3A, running hotter and aging faster.

A: About 5 hours at the standard 0.2C rate (roughly 4A), or about 2 hours at the 10A maximum charge current. Charging uses an 82.4V maximum constant-current constant-voltage charger: the pack charges at constant current to 82V, then holds 82V until the current falls to 0.02C. Do not exceed 10A - the protection board limits continuous charging current to 10A and trips at 15A ±1A.

A: Because the protection board is set that way on purpose. 82V works out at 4.10V per cell instead of the usual 4.20V, and the board's over-charge protection sits just above it at 4.15V per cell and 83.0V ±0.5V pack level. A 84V charge would cross the pack protection threshold, so it is not a supported charge voltage on this platform. Stopping at 4.10V gives up a small amount of charge capacity and slows capacity fade, which is a trade this platform makes deliberately.

A: The specification guarantees at least 500 cycles. Read the definition carefully, because it is widely misread: the cycle test runs until discharge capacity falls below 60% of the initial value, so 60% is the end-of-life threshold used to stop the test, not the capacity retention at 500 cycles. The pack is warranted for 12 months or 500 cycles from the delivery date. If your programme needs a specific retention figure at a specific cycle count, ask for the cycle test data.
