Old thread but here are my experiences.
I added 6 lipo drop in batteries
and 3 of 4 flexible panels made in Michigan in my Canvas. Please donít do this. I need to replace the canvas on the Bimini.
I 3D printed 4 clamp pins which retain a nut.
Two 11í bands with a slight curve of stainless. 4 panels bolt to it.
They are made in a rolling bed
which slopes down and then back up to maintain tension on the thin steel
as they pass through gas chambers. Now I have air flow but I may need a 3 Band to make them more stable. Iím avoiding putting a big metal frame on the back.
I helped build design and 3D print the housing for some remote electronics
I needed a 4.5w panel to charge a 2500mA battery
which ran a 3.5 micro processor.
There are 50 of them so I printed holders and turned to China
for lightweight panels.
Good for 3 years 19.00$ Good for 7 29.00$
The best panels made expire. I have a flexible panel 200 watt from same manufacturer in an aluminum
frame. Itís on itís 3rd boat as the winter battery tender
. Itís seen Canadaís worst weather
been buried in snow and ice 7 years ugly and running around 85%. Itís keeps batteries
monitoring system golden rods vents running 5-6 months in temps as low as -35C.
The panel holder is for a 4.5 but Iím working on a larger one to strap onto my Dinghy
battery a 20Amp
