My battery is shagged, I've found a li ion motorbike battery for just under £70 brand new. What's the crack with it all not had li ion before I take it the lamp will work as it's 12v and presume any 12v charger will work? It has no technical jargon on the site but has a number to call to find out. I'm going to call the fella but is there anything I need to know like amps or something like that ?? I have little to zero clue when it comes to electrics and gizmos
