Li-ion vs Li-poly battery? Answered
I m currently searching for a battery that has an high discharge rate and I found these two:
Li poly: http://www.ebay.com/itm/5200MAH-6S-50c-MAX-100C-22-2V-Helicopter-Airplane-LIPO-PACK-BATTERY-BEAST-Nano-/360510967745?pt=US_Character_Radio_Control_Toys&hash=item53f020cfc1
I need 40 volts so If I buy the Li-ion y will buy 4, and 2 of the Li-poly.
I want to know which battery will be better for an high discharge for about 3 seconds, and about 15 times. I will use the batteries to create an high powered electromagnet to move steel.
