Frequently Asked Questions
How many mAh is 300 Wh?
300 Wh equals 81,081.08 mAh at 3.7V (Li-ion nominal voltage). The mAh value changes with different voltages.
How do I convert 300 Wh to mAh?
Use the formula: mAh = Wh × 1,000 / V. At 3.7V: 300 × 1,000 / 3.7 = 81,081.08 mAh.
Does 300 Wh equal the same mAh at every voltage?
No. Higher voltage means fewer mAh for the same Wh. Use the calculator above to try different voltages.
Formula: mAh = Wh × 1,000 / V. Results assume nominal battery voltage.
