I'll have to chase up the supplier and see what they've been developing - www.plasmatronics.com.au - the website is geocities-bad but the products are good, and the support is great, e.g. my older, secondary controller which was slaved to the main controller developed a fault and kept resetting. It was way out of warranty but they fixed it free anyway.
The PL series from them are reasonably smart as far as lead-acid technology goes - PWM, adjustable boost/absorb/float cycle timing, presets for flooded-cell or sealed gel-cell, periodic equalisation, ability to switch to a secondary battery bank or alternative load when bank 1 reaches float, etc, but I've not seen anything relating to lithium technology. It wouldn't be a problem if I had to put in new controllers for a lithium battery bank - the PL controllers are very desirable on the second-hand market.
