Does anybody know if its possible to use a
solar cell panel to run a small electric bilge pump for a small highbanker? Will it have to be in direct sunlight ?
Mine is a Johnson 2200 gph bilge pump that pulls 8 amps at 12 volts
What size panel will I need and what do they cost? Can I run the output straight to the water pump or do I need a controller thing?
Or can I use a panel to recharge my 12 volt ,15 amp gel cell and how long will it take?

Nice batteries can be found in used laptop battery packs. I found 6, nice batteries inside a HP laptop battery pack. All test good and can provide some nice project batteries.
Some of the best on the market can be found in laptop batteries. A trip to the local computer repair shop can usually find some nice discarded batteries cheap.

They are the proper 1.5 volt and lithium batteries. They work well in my Tesoro that tends to chew up batteries fairly quickly. Will see how they hold up. They should not fade in performance as regular Alkalines do.
$20 for 4 is pretty good. Much less than the $80 I paid for my AT Pro lithium pack.
Why do so many metal detecting companies use 9V batteries for their products? What is this, 1979? 9V batteries aren't even used exclusively in smoke detectors anymore.
I want a new pinpointer but I'm absolutely appalled that so many of them use 9V batteries. Is there a logical or engineering reason for this?
After one year of testing my old Whites, Spectra V3i works almost 4 times longer. 18650 3.7V LiPo batteries holder, from my 3D printer, is ready:
What did you receive with your units specifically for charging?
In particular USA purchasers. Did you get adapter for 115vac plug in capability for charger??
I received an adapter for 115 vac outlet, but remember my unit is a test unit.
