<p class="MsoNormal">Thanks. I want to be able to run my WinLink go box that has 2x 50W VHF radios and a 100W HF so a max of 40 amps peak I think. That is what I have my Anderson distro block fused to anyways. All of the buck converters I’m finding on amazon
are either rated for 24 v with a 19-30v input range or are 10-20 amp. Could I use 2x 20 amp converters or should I break down this battery pack and re-do it in a better configuration?<o:p></o:p></p>

<p class="yiv6192959742msonormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A">I bought a 100Ah battery pack from Ali Express and I mistakenly purchased the 14.8v version which has a nominal voltage of 10-16.8v. That means
that I cannot use it for radio operation as it would be out of the 13.8 +/- 15% voltage range that all radios I have seem to operate within. It would be about 0.20V to 1.00V higher that what is within spec of the radios. My question is, is there anyone willing
to help me modify the pack to have a max voltage of 15.88 volts.<o:p></o:p></span></p>
