Just bought a lexmoto aspire. Is the battery under the seat, and is there a seperate key to turn, below the seat, to get the seat up to find it ? The ignition ket fits but does not go in all the way, and does not turn. Thank you. Also, can I use a 12 amp linwood electronic plug-in charger to charge a flat battery ? (input 220/24 V output 6-12 volt. Thank you.
