So looking everywhere, there is reference for it, and supposedly the EasySolar is just a MultiPlus - but there is just no Physical Trickle Charge connection that I can see.
According to one or two other posts it is J15 or thereabouts...and would normally be near the TSense and Relay ports - but not the case on this motherboard.
In above image - the one with 2 wires plugged in is the T-Sense, then Remote Switch, then the next posts are the Programmable Relay. There are no areas to attach further underneath the Positive Battery lead either...
Thoughts?
