<div dir="ltr">Hank,<div>That was me and have to stick with a certain battery size as it's a K-350 and the pods will only allow a certain size battery in them plus I have all ready built the trays for the batteries. I could certainly use AGM batteries if they were the same size as the led acid ones. Do AGM batteries have more amp holding capacity than the led acid?</div><div>Rick</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Oct 29, 2017 at 12:04 AM, hank pronk via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:Helvetica Neue,Helvetica,Arial,sans-serif;font-size:13px"><div></div>
