With the tracker and commuting in the dark 60 miles each way at silly o’clock, I was lucky to get more than a few hours out of the PMP. Certainly would never last the day. Might be down to the amount of electrics I had turned on though…
With the BV Ultra battery (B-124) I usually get 20hrs for the 750s 2ch, and it takes around 30-40 minutes to charge. Even with short journeys it usually provides enough charge to get through the working day. No idea what it’s like in the winter yet, but hopefully the lithium based battery can cope better with the colder temps.
