Charge your battery

So I have done two tests. For sure I get more use out of the battery, how much it is in actual use is hard to say. Around 20 percent more or less. 48V firmware goes to limp mode at just under 47V, 43V firmware at around 43V. Percentage shown on the display is even more messed up than before...

Still haven't had the time to try, I will update on this later.

There seems to be three 43V firmwares available here. Two of them are the same with different file names and the third is a eroad version. I have now tried all of them and they all have very long overrun, like a second at least. With the 48V version I did not have this and they seemed smoother...

Is that a 720Wh batttery? With those dimensions it could be.. This is not the most beautiful frame but it is not as bad as the early version. Still a removable battery and fairly much travel is very tempting.

There are charts on light carbon homepage. Leverage curve goes from 3.2 to 2.4 in a straight line, so according to that a coil would fit fine. Still my air shock is setup fine, but I do use tokens to have even more progressive, this is why I am hesitating on trying coil. I just like coil so...

Seems you are asking for the Dengfu E69. No idea about availability, but it is an interesting frame. https://www.emtbforums.com/threads/dengfu-e69-frame-bafang-m820-lightweight.37256/

I definitely need to test this, I am not so interested in more power, since I use trail or sport mode mostly, but I like to use the whole capacity of the battery.

This is interesting. Do you know the upper voltage limit for the 43V firmware? The 48V battery is charging to 54.2V if I remember correctly. At what voltage is 20% battery according to bafang display? And how low can you go on the battery?

No expert, but please make speedsensor with magnet attached to brake disc instead of spoke. Same goes for all the other frames as well of course.

Of course I cannot say exactly but seems correct. Comparing rides is hard with so many variables. I just really dislike the battery percentage shown and battery saving mode starting early. The extender is one way to have a light bike with enough energy normally and then add it when the need is...

Good question! I have two main batteries, on ~480Wh and one ~720Wh. Summertime I use the small one. I can ride around 3h and 40km on that one. I use mostly S assistance. Extender is nice when riding to my local hill, 30 minute journey, leave it in my backpack when going up and down the hill and...

Cells are rated 12.5A continuous. Highest I have seen on display is 620W, I rarely go over 500W. With 48V system should not be a problem.

Off-topic, but I finally built an extender for my LCE930. It is a 13S1P battery with 2170p cells. Connected with a battery balancer between main- and extender battery to motor. I didn’t want to make additional holes in the frame and connecting via charging port seemed too complicated, so I...

I also found having your bike upside-down helps. You can fiddle with the cables without the risk of motor dropping out, before you insert the motor bolts.

I had this on an earlier firmware, 48V eRoad version, but on the eMTB firmwares I have not noticed this or it is only minimal.

So I built a new battery with JBD smart BMS. Charged it to full and did a +2 hour ride on road, mostly Eco mode. Ended up on 78% battery on the display. Did another ride, without charging, up and down a small hill. Mostly S+ and some Boost mode. I recorded these figures: Minutes Display JBD...

When switched on, hold up and down buttons a few seconds. That will get you to menu. Move with up and down and select with middle button.

Go to AL sensitivity in Display information on the display. Put it to Off position, that will keep the light off when starting.
