7345 charger mod
In old post: > How does the PD9260 stack up to Parallax 7345? Salvo mentions how to modify and increase the charge voltage of the Parallax 7300. Could someone please point to the thread that conta...

That's exactly what I did to my Parallax 7345 converter. I have a +12V cable run of perhaps 20 ft from converter to batteries. Due to the line voltage drop, the batteries took 'ages' to charge. I opened up the feedback loop (within the converter), and added a resistor and small diode (diode clamps output voltage in case of a failure) to the converter. I then ran a small cable from the opened feedback to the battery. When not in current limit, the converter will now supply 13.7V directly at the battery, regardless of line drop. Charging times are significantly reduced.

Note here is even with the mode the best you will get is 13.7 at the battery terminals. A replacement will go into the 14.2 to 14.8 range depending on model.
