These configurations cover everything from street boards to mountain boards. Simulate them in CellBench to see real-world performance.
10S3P Samsung 30Q
Voltage: 37V nominal
Capacity: 9Ah / 333Wh
The classic eskate build. Fits in most enclosures, handles moderate hills, and gives 15-20 miles of range.
10S4P Samsung 30Q
Voltage: 37V nominal
Capacity: 12Ah / 444Wh
More range and better hill performance thanks to lower per-cell current. The go-to for longer commutes.
12S4P Molicel P42A
Voltage: 44.4V nominal
Capacity: 16.8Ah / 746Wh
Serious power and range. 12S voltage reduces current draw, and P42A handles whatever current is left. Premium build.
10S3P Samsung 25R
Voltage: 37V nominal
Capacity: 7.5Ah / 278Wh
Affordable first build. 25R cells are cheap and handle 20A each. Decent for flat terrain riding.
12S3P Samsung 40T
Voltage: 44.4V nominal
Capacity: 12Ah / 533Wh
Mountain board setup. 12S for torque on steep terrain, 40T for burst current when you need to power through rough ground.
10S5P LG HG2
Voltage: 37V nominal
Capacity: 15Ah / 555Wh
Maximum range on a 10S platform. 5 parallel groups keep per-cell current low for better efficiency and cycle life.
Hills pull 40-60A from your pack. See exactly how your chosen cells perform at those currents -- not just peak specs, but the actual voltage curve over time.
More P groups means less sag per cell, but more weight and cost. Simulate 3P vs 4P vs 5P with your expected current draw to find the minimum that still delivers.
Higher voltage means lower current for the same power. Compare a 10S4P to a 12S3P at the same load and see which one sags less and lasts longer.
Nothing ruins a ride like a sudden low-voltage cutoff on a hill. Simulate worst-case scenarios to make sure your pack stays above cutoff voltage even under heavy load at low SOC.
Proven cells that eskate builders rely on for power and range.
3000mAh / 15A
The most popular eskate cell. Affordable, widely available, and proven in thousands of builds. Great for 10S3P and 10S4P.
4200mAh / 45A
Premium choice for high-power builds. Handles extreme current draws with minimal sag. Worth the upgrade for hill-heavy terrain.
4000mAh / 35A
High-current 21700 for all-terrain builds. Excellent burst capability for steep hills and rough terrain riding.
Most electric skateboards use 10S (37V nominal) or 12S (44.4V nominal) configurations. 10S is the standard for most ESCs and motors, while 12S provides more top speed and torque. Higher voltage means lower current draw for the same power, which reduces voltage sag on hills.
Hill climbing draws high sustained current (30-60A from the pack). With a 10S pack, you need enough parallel cells to handle that current. A 10S3P with Samsung 30Q gives you 45A continuous, while 10S4P gives you 60A. Use CellBench to simulate a hill-climbing load and see how your voltage holds up.
The Molicel P42A (45A, 21700) and Samsung 40T (35A, 21700) are top choices for minimizing voltage sag under heavy load. Among 18650 cells, the Samsung 25R and Sony VTC6 handle high current well. CellBench shows you the actual voltage curve at your expected current draw, not just the peak rating.
Voltage sag directly impacts your top speed and hill-climbing ability. When cells sag under load, the ESC receives lower voltage and cannot deliver full power to the motors. Severe sag can trigger low-voltage cutoffs, causing sudden power loss. Choosing cells with low internal resistance and running enough parallel groups minimizes this effect.
