【Highlights】 ● It can protect the charging batteries when short circuit happens● It can support combined use for three parallel charging boards ( means you can charge eighteen batteries which have the same characters simultaneously )● It has 2OZ-thick copper foil， so it can withstand continual current of 80A● It can prevent each cell overcharge to improve the balance efficiency， and the later period of the balance charging cycle is shorted substantially● It consumes only 1 / 6 of the time when charging six batteries separately consumes to save total charging time● It avoids the trouble of replacing batteries repeatedly● Adopt 20AWG multistrand silicon line for the equilibrium output line ● Adopt 14AWG multistrand high quality silicon line for the main output line● Equipped with secure T plug silicon cap ● Apply high quality AMASS output plug ● Thicken PCB copper foil， to allow 30A charging current securely 【Specification】Dimension: Approx. 14.2 x 6.7 x 1.7cm Package weight: 0.191 kg Product size (L x W x H) : 14.2 x 6.7 x 1.7 cm / 5.58 x 2.63 x 0.67 inches Package size (L x W x H) : 19.0 x 9.0 x 4.0 cm / 7.47 x 3.54 x 1.57 inches Package Contents: 1 x LiPo Charging Adaptor Board Charge Balance Parallel Connect Plate1 x Cable1 x Bilingual User Manual
