zacc, what to watch out for:

is the temperature sensor external, can it be connected to the battery?
What are the charging voltages at various levels, and can they be adjusted to suit the battery type?

Most likely the switch over from absorption to the lower float voltage will happen if the charging current has dropped to a low (typically 10% of peak current) value.
What happens if one or more loads are connected while charging, the charger will get fooled into 'thinking' the battery still needs more time to absorb and keeps the high absorption voltage up.
This potentially overcharges the battery, unless there is an (adjustable?) overriding time limit for the absorption stage.

Check for the usual things like c-tick and Australian approval number.

Best regards, Peter

Peter posted some valid points and did not say that jaycar were selling rubbish.

Posts like yours make me wonder why I bother browsing these forums at times.
