Battery Charger Options [RE-wrenches]

[Kurt Albershardt]

<x-flowed>
They are constant voltage chargers and hold the voltage stable while current falls off.

The IQ4 does a pretty decent job, better than the IQ3 did (it used a 90-minute timed bulk phase which ~sometimes worked out well depending on your battery bank size.


They are not temperature compensated, unfortunately.  I've asked about it several times over the past few years and was hoping they'd add it with the revised design (to accommodate the IQ4) but no luck...
