Name: G.T. Power B3 2-3S LiPo Charger
Brand: G.T. Power
SKU: GTP-GT-B3
Price: 27.30 AUD
Availability: InStock
Rating: 4.65 (20 reviews)

The exact charging time depends on the capacity (mAh) and voltage (2S or 3S) of the battery you are charging. The G.T. Power B3 outputs 1.5A for 2S (7.4V) batteries and 1.0A for 3S (11.1V) batteries. To estimate the charge time in hours, divide your battery's capacity in amp-hours (Ah) by the charger's output. For example, a flat 2S 3000mAh (3.0Ah) battery will take approximately 2 hours to charge (3.0Ah ÷ 1.5A). A 3S 3000mAh battery will take approximately 3 hours (3.0Ah ÷ 1.0A). The final balancing phase may add a small amount of extra time. Hope this helps :)
