I purchased the Bosch Rotak ergoflex 43Li from Amazon UK, delivered to Australia. Came with 2 batteries.
Perfect constant speed. Stops immediately if grass catcher full or encounters an obstruction. Excellent electronic stall protection
I believe it uses regenerative techonoogy to recover the rotational energy of the blades at the instant it is switched off. Perfect
Got my 43 LI 4 years now and suddenly it stopped with a bad burning smell. Motor broke an d Bosch lets me buy a new one.Very good solution it was for my lawn, very bad durability however.
The "regenerative technology" may be nothing more than a diode. Most electric motors will turn into generators when the power is switched off. The diode would stay in circuit to direct the motor voltage back to the battery. However, the energy stored in the spinning blades & motor electric field would be very little compared to that required to cut grass, & would make little or no difference to battery run time.

I got 8 months out my bosch rotak 43 before the motor burnt out. Maybe one of a bad batch back to petrol for me as it was also painfull mowing as i have sprinklers and lots of object that a cable likedto catch. Thebosch was powerfull enough ut considering the size of my yard was not very big i wouldnt buyone again as iwas hoping to atleast get 3-4 years out of the machine. Thankfully bunnings was happy to exchange, as i was in no mood to be mucked around by warranty centres and having to wait for it to be repaired.
