Lifepo4 Voltage Chart: Understanding Battery Capacity

LiFePO4 can discharge down to 90-100% of its rated capacity, unlike lead acid batteries, which should only be discharged to 50% to prevent damage. How Battery Voltage and Capacity Are Related. LiFePO4 batteries exhibit a flat discharge curve. For most of the battery''s capacity, the voltage stays relatively constant.

Maximize Your Power: The Ultimate Battery Capacity Calculator

Calculate the discharge time (T) in hours until the battery is depleted. Multiply these values to find the capacity (C) in ampere-hours (Ah): C = V x I x T. Step-by-Step Guide: Mastering the Battery Capacity Calculator Our Battery Capacity Calculator is designed for ease of use.

How to calculate battery run-time

A rule of thumb is that for a 1 hour discharge rate (i.e. drawing 10 amps from a 10 amp hour battery, or 1C) you will only get half of the rated capacity (or 5 amp-hours from a 10 amp-hour battery). Charts that detail this effect for different discharge rate can be used for greater accuracy.
