Can someone tell me what sort of battery I should purchase (SLA, AGM, ???). What capacity should I be looking at (Amp Hours) to last a full night (preferrably 2 nights)?
Finally, does anyone know a good supplier in teh Sydney area?
Cheers

50% discharge on an SLA will bring you down to 12v and you dont want to go lower.
Full night 8hrs? Two nights 16hrs.
16hrs x 8amp x2= 256AH battery
