[PSUBS-MAILIST] AGM Batteries



I am building a K-350 and the consensus from the group was to go with AGM batteries. I have spent quite awhile on line looking and there are so many options. I am using the 12" schedule 40 pipe for the pods so they would have to fit in those dimensions. There are also different amp rating and such. Can anyone offer some advice on what specific AGM battery I should buy?

The way I understand a real basic periscope (with regards to what is in
between the two prisms, or "90 degrees optical bends") is actually quite
identical to what happens when you look through a combination of two
telescopes pointing against each other.

You know how things looks smaller when looking the wrong way through a
telescope (or a pair of binoculars)... this will be like your lower
section of a periscope, whilst the upper section of the same periscope
would be like the other telescope, but now oriented in its proper
direction of view.

Best regards,
Jens Laland
