Did anyone else run out and buy a 48V EG4 battery after watching Wills Video?

Rather than EG4, consider a couple of Ampertime 12v 400ah. Just a bit more money, but quality is just as good.

On second thought, I forgot that Signature Solar has a 12v version. I have three 48v EG4 from Signature Solar, and opened one up. Very impressive quality, and cost less than Ampertime.

Can these batteries be drawn down from 48 volts to 12 volts?

No. 12V in a 16s set-up would be 0.75V per cell, which would be a dead cell. You can't take a cell below 2.5V, or 40V for the pack.

your lack of knowledge is rather disturbing and will lead you into getting hurt or worse a family member. I am not telling you what to do but it would be to your advantage to learn everything you can before taking on this adventure.

MarathonMan Maintenance guy,
Thank you for your response. I am inexperienced, and have only really been watching videos and learning on the surface. I am a ways off from actually building the electrical system. Hence me coming here and asking a question and so far receiving some good feedback. I will continue to learn and thus ask questions. I am a long time lurker and first time poster.

Regards,

Ian

We have a 12v version.

Thank you Richard, I'll look into it!

Thanks for the response, still got a lot of learning to do.
