Converted a 2015 E4 to Lithium and did about every error possible in the process. But once rectified, this E4 is fabulous.
Lithium Gods (Mike) sold me the battery (Samsung) and walked me through fixing each bonehead mistake (and I made many).
- wrecked 2 chargers (Dave (Inwo) repaired one)(Thank you Dave)
- poor contacts on the BMS (voltage measured good contacts because I was pushing the volt meter into the contact so it showed good but when removed, the contact disconnected and the cart wouldn’t run.
- Loose connection on battery terminal which caused occasional cart shutdown. Again, Mike figured it out by giving me clues on how to catch the problem by screen shot of BMS while cutting out. Check all connections before wasting other people’s time.
I owe a huge thanks to Mike and Dave for getting this rooky through all my errors. Every problem was my own incompetence. Not a single problem with the products.
