<pre style="margin-bottom: 12.0pt;"><span style="font-size: 12.0pt;">I wish I shared your optimism Scott on the LG Prime 16 being better battery than the LG Resu10. When I field tested the Resu 10 with <br />Schneider in 2017,<br />the specs on the unleased 48VResu 16 were the same for charge and discharge as the Resu10. You would think the larger battery would be better<br />but it was not. The same BMS I would guess.<br /><br />The fact that you can't use any of these LG batteries without the loop closed to the inverter is a serious flaw (they shut down without the heartbeat)<br /> that people like Discover AES learned from. Something very wrong that LG is still in the dark ages of a home battery, in my opinion.<br /><br />AES did not carry out this poor design policy and built the perfect LFP for my clients and my wife and I.<br /> LG is NMC and even advertised them installed in a Kitchen?<br /><br />We killed the Resu 10 with too much XW charge current BTW. The dead ones went out to the desert of California to be recycled. Another story.....</span></pre>

<p class="v1v1v1v1msonormal"><span style="font-size: 12.0pt; font-family: 'Verdana',sans-serif;">We have 7 or so batteries under recall and 3 that needed warranty support.

<p class="v1v1v1v1msonormal"><span style="font-size: 12.0pt; font-family: 'Verdana',sans-serif;">LG seems to have improved its position and has replaced in a more timely way some of the failed batteries.</span></p>

<p class="v1v1v1v1msonormal"><span style="font-size: 12.0pt; font-family: 'Verdana',sans-serif;">I'm hoping the LG Prime 16 is a better battery than the LG Resu10. Seems so and I like the high discharge capability that really pairs well with a SE11400 Energy Hub inverter. We've had one warranty of a Prime 16.</span></p>
