Hi all,
How do Lithium batteries fit into all of this ?
Do they respond to radiant charging ? has anyone tried ?

A radiant charger would be ideal in an EV, say 4 batteries, two for drive, one charge/source battery, and one to run auxiliaries.

Lithium battery's can be charged this way with care, but there are problems. Many Lithium batteries have a built in circuit for charging and this will be damaged by the spikes. Other people who have charged lithium have experienced the batteries explode and that happened to me too. I do not know if there are any of the "overunity" effects that you find with lead acid batteries or recover of dead cells as I gave up on them.

It has been done but I do not know the details and if you choose to attempt it, be careful, document everything and report back your results.

thanks for that, it's good to know what territory you're entering. It doesn't look like there will be many Lithium batteries without a monitoring circuit available !
So if one was to use them, it sounds like they would have to be charged minus their BMS as individual cells, the re made into a pack after charging ! sounds like alot of hassle, a shame considering their power to weight.
But I suppose if you're charging your batteries for free, do you care ?
