Thread: Charging Batteries Via Anderson Plug

Hi Scott, because the auxiliary battery is an optima, you can use either the AGM or Calcium setting because the Optima will tolerate 15.1v while charging.

NOTE, this is assuming your cranking battery is NOT an AGM.

I assume you run the Anderson plug off the optima battery, ?


Tim if you were connecting solar panels to the Anderson plug will the main battery charge if I have a SC80 control once the optima has charge ?




Cheers Ean

Thanks Tim, yes cranking is Ca.

In that case, is one setting preferable? I have the same setup but with an MXS5.0 charger.

A different Scott

I think both settings put out about 14v so I don't think it matters. Someone correct me if I'm wrong please.

Cheers
Scott.

Hi Folks, it is important to make sure you know what type of cranking battery you have.

The early versions of the D4 ( such as Scotts ) have Calcium/Calcium ( Ca/CA ) cranking batteries and the higher charge voltage is fine for the cranking battery and the Optima.

Later D4s have AGM cranking batteries and the charging voltage MUST NOT EXCEED 14.7v, so for the later D4s, select an AGM setting.

if in doubt, select the lower setting

Why do you need a battery charger if you have a traxide system? I have a traxide with sc80 but was under the impression that the alternator did the charging of both batteries😕
