    Default Test/review of Golisi IMR20700 3200mAh S32 (Black) 2018

    Golisi IMR20700 3200mAh S32 (Black) 2018

    Official specifications:
    • Size: 20 x 70mm
    • Model: 20700
    • Capacity: 3200mAh
    • Constant Current: 30A
    • Nominal Voltage: 3.7V
    • Charging cut-off voltage: 4.20±0.05V
    • Cycle times: >800
    • Charging Time: 2.5H(with Golisi Charger)
    • Operate temperature: Charging(0-45?), Discharging(-20-60?)
    • Storage Temperature: Room temperature, dry place

    This battery is a high current one and is of the never sizes.

    The two batteries do not match completely, the capacity is nearly constant at any load.

    At 30A I had to stop early due to temperature.


    This battery looks like a fairly good high current cell.

    Notes and links

    The batteries was supplied by Golisi for review.

    Looks like yet another Panasonic NCR20700A cell. Great performers as expected, though the cell getting hot at 30A discharge is a bit concerning.

    Regardless, it's remarkable just how far battery technology has come...
