I makes a huge difference
I use this on a Bafang BBSHD MTB conversion and it is a total game changer. I recently upgraded from the BBS02b model to the BBSHD and I got exactly what I expected to get: a faster, more powerful bike that has a shorter range. I started carrying both of my bike batteries with me and, on longer rides, I would stop to change the plugs when one battery ran out of power. That's when I started looking for a switch that I could use on-the-go to change batteries without stopping. So I got this little black box and was happy that I didn't have to stop to change the plugs anymore. But I also think (and this is just a subjective, unquantified feeling) that my motor works better with this attachment. I think there is less voltage sag so I'm able to get up to speed quicker. And it extends my range because I can use more of each battery. The increased range and faster acceleration has made the transition from the BBS02b to the BBSHD drastically better and more enjoyable. I was just looking for a switch but this device came with a couple of game changing advantages. I definitely would recommend this converter for anyone riding with 2 batteries.

Works great
I hooked it up to my folding e-bike added a 52 volt battery to the rear rack and doubled the mileage.Great product my original battery is 48 v 20 ah and the one I added 52v 20ah no heat ride 40 miles without stopping! Then I pedal assisted home at 20 mph and still had 2 bars out of 6.

Does its job.
I have a 48v scooter that I installed this balancer on. The 18AH internal battery coupled with a 10AH external battery gives me over 50 miles of range. Batteries seem to discharge nice and evenly. Good get. #2 en route for my other rig.

Works great !
Works great! I paralleled it to two 52 V batteries on my bike. I went on a 30 mile ride running the bike hard and it still ran 30 mph on the way back. The box was barely warm when I got home which tells me it’s not wasting any power.
