If you’re going to do it anyway - These would be good batteries > [@Lifepo4 Lithium Conversion w/BMS 28s-30s 100ah - New Cells](https://community.electricforum.com/t/lifepo4-lithium-conversion-w-bms-28s-30s-100ah-new-cells/22495): > > Ordered these to convert my 2002 GEM from lead to lithium. I have changed directions in a major way, ended up with a 2016 E6, got tired of waiting, and went with one of LG/INWO’s conversions which is an excellent way to go. This one is more for the DIY’er and slightly easier on the wallet - you will need to know how to hook these up and will need to wire them, setup the BMS etc. If you’re looking for turn-key/■■■■■ proof with support, you’ll get a little help from the community but this is prob… When you abandon the front batteries, you could move the controller up there which would get more airflow. I was going to do that to mine but said is enough… time to upgrade --- _[View the full topic](https://community.electricforum.com/t/new-to-gem-bought-2002-e825-for-hilly-area/22061)._
