Hi John--
Yes, we might have touched upon some practical, affordable uses. I
suspect many readers would like to do more as more becomes feasible.
Let's try to keep on our toes and follow along with developments--
which are considerable. I peeked into charger controllers a bit.
Seems the main thing they do is prevent reverse flow when the PV
panel output drops (low/no sun).

Morningstar is a big name. They're a few bucks more.

In the case of Solar Panel (charger) ->MAHA cig adapter cable -> MAHA
charger-> Sony "M" Lithium Ion battery, I believe the MAHA would
simply shut off when the voltage/sun dropped (sans charger
controller). As I mentioned, your 20 watt panel could probably
charge two batteries at once. There are compact, inexpensive Lithium
Ion battery chargers that come with 13.5 vdc/500-1000ma wall warts.
Here's one that charges two batteries at once:

One could insert the charger panel output into the Lenmar BCD641
charger (instead of plugging them it into the wall wart). At $160
for the 20 watt panel, that comes to ~$200 for a packable two battery
per sunny day solar charger. Maybe condition the batteries on your
MAHA every now and then. Rob D.
