Got a lift raymond serial: es-d-04-13008 with error code 45 and code 8F i think one related to a battery problem. Main problem is the guy changed one cell battery and tell us the other was fine, but after 1 month battery get 100% charge and within 2h of usage battery is drained, just wanted to know what those code mean incase something else may conflict beside the battery. The book cost 108$ with 3 week shipping, if someone could send it to me pdf too. Thank you
