This is my 3rd cylinder and still super efficient. This will be used to open a ventilation hatch on a roof. 50mm stroke in 2 seconds because the cylinder provided under 12V was tested voluntarily with a used 9V battery. Vacuum 7.33v charged by the 6.57V 48mA jack. The piston takes longer to travel the 50MM of stroke. With a charge and attempt to block the piston manually, the voltage supplied by the battery drops to 5.4V under 80mA. Then the piston continues to finish its stroke correctly. I am planning a 9v solar cell with a super capacitor as a backup battery. The results are above my expectations.

I bought this to modify my Huina 1573 dump truck with a WPL 6X6 chassis. Pretty stron for it's size. Quality is good too!
