Solar battery charger

[cpedw]

Silkie,
Didn't you ask about a Maplin version in the other place recently? This one http://cpc.farnell.com/jsp/Batteries+&+ ... =BT0326762 from CPC looks to me like a bargain for keeping the battery topped up when you are away from the boat and the sun is shining, as it does.
Note that CPC are a bit coy about the VAT, but still a good price I think.
Regards,
Derek
