LiPo Charge Time Calculator

Estimate the ideal CC charge time for a LiPo pack at a given charge current.

Ideal charge time
60min
constant-current estimate

Ideal only — CV phase, balancing and termination make real time longer. Never exceed the pack’s rated charge current.

Formula

  1. 1.Ideal Charge Time (min) ≈ Capacity (Ah) / Charge Current (A) × 60

Worked example

  1. 1.Inputs: 5000 mAh at 5 A (1 C).
  2. 2.Ideal = 5 / 5 × 60 = 60 min; real-world ≈ 70–90 min with CV balancing.

Assumptions and limits

  • Not a guaranteed finish time — CV, balancing and charger limits all extend it.
  • Never exceed the manufacturer charge rate or bypass charge safety.

FAQ

Why does my 1C charge take longer than 60 min?

The constant-current figure skips the CV taper and balancing tail — normal, not a fault.

Assumptions

  • Constant current to full — an idealization.
  • Real chargers taper at the CV stage and balance cells.
