    Group Build - 12v Battery Module (EVE 280AH)

    @vtx1029 Your comments are welcome and have value. Since a number of "fixture" and "compression" threads have been going on for some months, we are all still learning what the cell specs actually mean. @HaldorEE is working with a load cell to try and accurately characterize the cell's...

    Group Build - 12v Battery Module (EVE 280AH)

    The Seplos video was my initial inspiration that got me thinking about this simple solution to bundling the EVE cells. The main problem (easily fixed) was it was not strong enough to support compression. Neither was the ebike bracket that @lexio shared. Thicker plastic should solve that...

    Group Build - 12v Battery Module (EVE 280AH)

    Yes. I decided to start with a 12v battery module (compressed), but scaleable to at least 24v. After that, solar and chargers. And then, . . . ? The battery is the key "building" block for what I have in mind. Great find. That is what I have in mind, but with some compression. In recent...

    Group Build - 12v Battery Module (EVE 280AH)

    @sshibly If you are referring to the entire rackmount module, I totally agree (for a 12v version). HOWEVER, at this time, I am only interested in the plastic holder, redesigned for the EVE 280AH cell size. Besides, if size does matter (and it does), I am suggesting shortening the plastic...

    Group Build - 12v Battery Module (EVE 280AH)

    After lurking for a few months around the forum, I have learned much and seen the incredible knowledge, technical skills and impressive battery builds of forum members. These have largely been purpose-built and size-constrained, and thus "one-offs", primarily due to their locations (yachts...

    DIY LiFePO4 Solar Generator for Disaster Preparedness

    I appreciate your comments and they certainly apply to most people, but I have not seen "builds" that will assist me in what I have tried to describe to you and the rest of the "community". Initially, 120v AC output has no place in what I want to do. And, it may never be added. Neither does...

    DIY LiFePO4 Solar Generator for Disaster Preparedness

    THANKS for the response. Although I have looked at the Bluetti AC200 and many others, they are not appropriate for the goal I am trying to address. I want to develop a "proof-of-concept" configuration that is modular, scalable, reconfigurable and repairable by me, using only the resources I...

    DIY LiFePO4 Solar Generator for Disaster Preparedness

    As a new, first-time posting member, I was recently inspired by the "teardown" of the 12v 100Ah Battle Born battery by Will. Although this battery (when purchased) won't meet my goal, what is inside the case may work as part of a DIY build as it appears to be a high quality battery. Goal Build...
