Lithium
« on: March 03, 2020, 11:20:04 PM »
Looking for advice on lithium charging. I build 50 amphr lithium batteries for ebike use. 18650 cells
12p 14s with common wired bms. I would like to use these in my wanderlodge with 6 300wt panels. I have a classic 150 with 400 amp hrs a 12volt currently. I would like to dedicate 2 panels to 12volt (kid charge controller) and use the other 4 panels for 48 volt lithium with the classic.  I have been using solar for ten years and would like to learn about using lithium  as well as having a redundant system. I'm not sure about charging with the classic.  I charge my lithium with dedicated chargers for specific chemistry. Anyone out there using lithium.  I would appreciate any help.

Thanks Bill Ezrow

Regarding you ebike battery pack building - have you read Michah's book ?
https://www.amazon.com/DIY-Lithium-Batteries-Build-Battery/dp/0989906701/ref=sr_1_2?keywords=build+your+own+lithium+batteries+for+ebikes+book&qid=1583300462&sr=8-2
Sounds like you have the ebike battery building down and yes it is easier using their dedicated  AC chargers .

There was a recent discussion on the forums here about charging lithium batteries with the Classic . I will look for it and post the link.

Here are some recent discussions on lithium

This is an older discussion

If you go to the first midnite forum page and type in lithium you will see a lot of past discussions ( the search only works on main forum page for some reason)
