I have a Nexpower lithium battery for sale that was installed on 5-16-24. It is the upgraded v2 I believe. It was installed with new wiring and the wide flange flat nuts and torqued to spec. Never had any problems with the battery. Selling because the engine went out on the car. Selling for 1000$ shipped to you. Have more pictures can give on request because file size is too big to upload.
