<div dir="auto">Hi David I think although it is 450 volts out, the battery is actually moch lower voltage and has a buck boost charge controller. It bucks the voltage down to charge the battery and boost the voltage to serve the load. If you open the battery and rewire you will need a BMS, you can find on line but you need to know the battery voltages I think it is 3.8 to 4.1. NMC perhaps some one on line knows </div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jun 30, 2023, 11:40 AM David Katz via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">I have an LG Chem RESU10H Battery that was originally sold with a SunnyStorage inverter. Does anyone know if there is a way to turn on the battery output terminals so it can be charged without the inverter. No lights come on when you turn
on the main switch and the output breaker. There is a small terminal strip for control wires. There is a 12V + and – terminal and a Batt En terminal. Does any one know if powering the Batt En. Terminal turns it on? I am going to try that but I am not sure
what voltage that terminal wants to see.<u></u><u></u></p>
