<p style="margin-bottom: 0cm;">Hi Gordon,</p><p style="margin-bottom: 0cm;"> </p><p style="margin-bottom: 0cm;">I emailed Kjell and this is what he said:</p><p style="margin-bottom: 0cm;"> </p><p style="margin-bottom: 0cm;">Munin needs 13,8V +20% -5% for the best
performance. At least 20A continuous current is needed, 25-30A peak.</p>
