Here are some pictures of the batteries and the install: ![IMG_4849](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/a/a5ad94b1f87d6475d6f6d539a83a51ffa47da6e3.jpeg) ![IMG_4875](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/9/9d0badf1f91992e17358403d896d1571852f04cd.jpeg) ![IMG_4882](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/d/d98ee48a6f9750df8b8e5f9e5cf2671ec1f36b57.jpeg) I’m working on the charge cycle. Currently the QuickCharge is set to “Deep cycle wet and shut off”. Seems to keep the voltage too high at the end so I have been monitoring and shutting it off manually. That temperature is from the side of the charger. ![IMG_4889](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/d/d08b50d6770199dcce6451be168ab2ee7f6814e0.jpeg) The batteries have stayed very balanced once the charger stops and throughout the discharge. I have measured about .02 V difference across all 25. I haven’t done any long rides yet. Only about 8 miles so far. I think I want a BMS to add low voltage cutoff protection, better charge management and more info about the battery state. I’m looking at different chargers too. --- _[View the full topic](https://community.electricforum.com/t/2005-gem-e2-lithium-conversion/16607)._
