How to Use This Calculator
  1. Enter the LiPo or LiHV battery capacity (mAh) and your charger's charge rate (C-rating).
  2. Set the number of cells (e.g., 4S, 6S) and current charge cycle count.
  3. Enter the maximum rated cycles from the battery manufacturer's datasheet.
  4. Review charge time (min), charge current (A), battery health (%), and remaining useful cycles.
  5. Charge at 1C for longest battery life; avoid charging below 20% or storing above 4.2V per cell.

What each input means

Battery Capacity
Battery capacity in milliamp-hours.
Charge Rate
Charge rate multiplier (1C = capacity in 1 hour, 2C = half the time).
Number of Cells
LiPo cell count (e.g., 4S, 6S).
Current Charge Cycles
Number of charge cycles the battery has completed.
Max Rated Cycles
Maximum charge cycles before significant degradation.
Storage Voltage per Cell
Target per-cell voltage for long-term storage.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Battery Capacity = 5200, Charge Rate = 1, Number of Cells = 6, Current Charge Cycles = 50 = 6 input(s) provided
  2. Calculate Charge Time
    Charge Time
    78 = 78
  3. Calculate Charge Current
    Charge Current
    5.2 = 5.2
  4. Calculate Battery Health
    Battery Health
    83 = 83
