Frequently Asked Questions
How many mAh is 4,000 Wh?
4,000 Wh equals 1,081,081.0800000001 mAh at 3.7V (Li-ion nominal voltage). The mAh value changes with different voltages.
How do I convert 4,000 Wh to mAh?
Use the formula: mAh = Wh × 1,000 / V. At 3.7V: 4,000 × 1,000 / 3.7 = 1,081,081.0800000001 mAh.
Does 4,000 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.
