All suggestions look good and merit looking into somewhat. I will need to do some research through the fall to see the efforts needed behind the different options out there. I will need to pay particular to the electrical and how to connect / retrofit to the existing connections if I don't go...

Why limit your self to a Reention Dorado 48V 21ah Battery? There are plenty of other options out there. :D :bolt: Guess I was just showing my ignorance to this technology. Make and model is not important to me. I'm more interested in the plug and play function rather than retrofitting...

OH so my chances of find a good quality battery for a good price is pretty good then, huh.... :wink:

I don’t think I will need to worry about “configuring” a new battery. The Reention Dorado 48V 21ah Battery seems to be rather common as far as replacement batteries. Easily found on eBay for something like $1200. On Amazon it’s a good $850 plus. Keep in mind these are Canadian dollars. That...

Managed to bring up the lower cell pack to 4.0 V . Reconnected the BMS harness and charged the battery for 24 hrs. First row of figures is freshly off the charger. The second row was after a 12.1 km ride. Mainly pedal assist. Black & Green = 4.16 V = 3.84 V Green & yellow = 4.15 V = 3.84 V...

I will likely go the way of buying a battery but I need to make absolutely sure my shutdown issue is the battery. I'm still not sure it is not something else at this point. As I'm typing, I have a 5V charger (with a 100W light bulb) charging the 3.4V cell pack. I want to bring it up to 4.0 V...

Thanks ebuilder, appreciate the suggestion and probably would have went that route 30 years ago…heck even 10. Would have loved one of these back then to push the limits a little and have enough power left over to bring me back. I’ve always enjoyed new projects , challenges and lost causes...

In for a penny, in for a pound I guess. Opened it up. It was easy enough to slide out. Harness pins are way too small to charge 4.0V with anything I have in house. So I will see if I can charge it on the pack somewhere by chasing the wires. Guess I'll take the winter to slowly see if I can...

Boy you guys are way ahead me on diagnostics, cause vs. symptoms but I believe I get the gist of it. Well at least I hope I do. Was opting for charging just the group of 3.6V but the point of why that group is at 3.6V to begin with and will likely degrade again , somehow makes sense to me. SO I...

The harness not seated well was me. I was trying the BMS reset thing I read about. I had just placed it lightly back for the picture. It’s snap in good now. Not sure if I understood the direction properly but this is what I got. (Polarity was the same all the way through. Starting from the...

I believe 53.4 - 53.6 Volt is as high as it's gone with an overnight charge. I can try leaving the charger for longer if that would help? I didn't think that one volt short of 54.6 meant a big deal for a 2-3 year old battery. Regardless, below is the pic asked for. Well i believe this is what...

Thanks again for the detailed guidance. It is definitely a good reference for me. I have a little experience with ebikes as I have done it once before. As they say, I know enough to be dangerous. My issue here was the symptom of shutting down. I have no experience on what this could...

Wow, thanks for all the input everyone, really appreciate it. I will get to the pics requested in due time. Unfortunately life is getting in the way of FUN right now. Older parents to take care of and stuff. As to the term “MacGyver-ing”, I was just dating myself for lack of a better word...

Opened up the battery easy enough, 4 screws. Tried the reset thing by disconnect the harness but not much changed. Actually no….. This time the power still cuts off but the display remains on. So the system still has power but the throttle and PAS has no affect until I shut it off and on...

I think your old saying hits the “nail” right on the head , pardon the pun :D . In my experience this is called a single point critical failure and is usually avoided like a plague in all designs? Would we design electrical systems without fuses? Not sure if Rize realizes what kind of a hit a...
