Tag nrho lub zog ntawm lub roj teeb yog xam raws li: Wh=Voltage (V) × Capacity (Ah). Piv txwv tias ob lub tshuab muaj peev xwm ntawm 100Ah:

15S:

• Nominal voltage: 48V
• 48V × 100Ah=4800Wh

16S:

• Nominal voltage: 51.2V
• 51.2V × 100Ah=5120Wh

Qhov txawv:

• 5120 - 4800=320Wh
• 320 ÷ 4800 ≈ 6.7%

Raws li peb tuaj yeem pom, nrog tib lub peev xwm 100Ah, 16S system yeej khaws ntau lub zog.

Cov txiaj ntsig tsis tso tseg. Qhov tseem ceeb tshaj plaws, 16S system ua haujlwm ntawm qis tam sim no. Vim li cas qis tam sim no muaj txiaj ntsig? Tsawg tam sim no txhais tau tias tsis muaj hluav taws xob tsawg, txo qis cable, kev sib txuas ruaj khov dua, thiab muaj kev nyab xeeb dua tag nrho.
