I would not recommend using that type of battery for your application. We have sold a few small 24 and 48V systems using LiFeBlue and Relion Battery and had a problem with one system. The EMS on a drop-in Li battery is internal and functions independently. If one battery turns off on a fault, you loose all power on that string. With a parallel path (string) still functioning, the strings are now becoming unbalanced. When the battery is restored, you have 2 different SoC\u2019s for the 2 strings. Not a good scenario and it could lead to cascading trouble. </div><div class=""><br class=""></div><div class="">I recommend using a battery system with external EMS (example Elite Power Solutions <a href="https://www.elitepowersolutions.com/bms/" class="">https://www.elitepowersolutions.com/bms/</a>). Everything is field serviceable and if the EMS does turn off, there are simple ways to continue using the battery until it is repaired. Much happier customer. </div><div class=""><br class=""></div><div class="">You can contact me off the list or call if you would like further advise. <br class=""><div class="">

I want to make sure a drop-in replacement is the best option for this client, or should I consider another option?
