How Does the 10S3P Configuration Affect Battery Performance?

The 10S3P (10 cells in series, 3 in parallel) design provides 36V nominal voltage and 10.5Ah capacity. Series connections boost voltage, while parallel groupings increase current capacity, enabling longer rides (up to 30 km per charge) and stable power delivery during acceleration. This setup reduces voltage sag and extends cycle life to 500+ charges when maintained properly.

The 10S3P configuration optimizes energy distribution through its hybrid series-parallel design. Each parallel group of 3 cells shares the current load, reducing stress on individual cells during high-demand scenarios like hill climbs. This arrangement also provides redundancy – if one cell fails, the remaining two in its parallel group can temporarily compensate. For comparison, a 10S4P configuration would offer higher capacity but add weight, while a 10S2P setup might overstress cells during acceleration.

What Safety Features Are Built Into the 10S3P Battery?

Premium 18650 cells with UL certification, a multi-layered BMS, and flame-retardant PVC casing ensure safety. The BMS monitors temperature, voltage, and current, disconnecting power during faults.
