I bought 3 batteries.. 2 G10Ts, 1 G20Tiis.. one of the G10Ts came with the Spider V..
Got a receiver.. G10S.. The batteries charged only ONE Time.. the one that came with the spider V is the only one that will charge.. (blink green or steady green) 45 minutes later, it goes red and stops.. the other two will not charge at all.. I have to say.. out of ALL the Line6 products I have used, owned, and sent back.. the Spider V 240HC is the only Line6 product that (so far) has not failed.. The company was sold off, I believe, and the quality has really crashed.. sorry to say.. these guys have a great idea, but not the engineering accumen to create products that will not fail.. they release products before they are ready, because they need income.. this is a bad development model.. sorry to say.. but sweetwater says they will replace all of them.. and we try again after $500+ invested in these Relay products.. Buyers beware.. The tech guys at Line 6 were great, but they just can't solve the problem.. that is very sad.. very sad.
Best luck future customers.. hope you have a better experience
