A2B help needed! I had my frame battery pack rebuilt using Tesla cells but the builder failed to return the original screws/nuts and Plastic Stanchions that position and hold the bms within the casing. It doesn’t appear as if I’ll ever have them returned so I’m in need of (at least) the plastic...

I installed these (different tread pattern) https://www.amazon.com/Tire-2-75-Motorcycle-Performance-Street/dp/B00QUBZY7M after burning through 4 sets of Kendas the new tires are quite heavy and I could feel the extra load when accelerating, could feel the change in front suspension over bumps...

I have an A2B metro with 12 fet set up for 30~84V. Have been running a 36V pack on the rear rack since the frame battery went south. I recently had the frame pack rebuilt with Tesla cells but haven't had time to reinstall and set it up. I plan on switching between 36V and 72V depending on my...

My .02 : I was getting slow leaks when I first got my metro. I ride animal trails, dirt paths and roadways (to get to the off the beaten path stuff). I checked the inner tube and found multiple pin pricks, actually cactus spikes in the tire was puncturing the inner tubes. I added slime (hate the...

When I read your story I was struck by how many similarities there are and how the responders have advised you. My plight is here: http://endless-sphere.com/forums/viewtopic.php?f=14&t=53978 It is just shy of two months now and what I have observed is that my 36V sun_Power battery generally has...

it was a slow process but several days ago the battery took a higher charge. I'm done measuring unless an issue arises. wj

<quote>For sure, you took a not balanced pack, and hammered it into even less balance on that first ride.</quote> My take is that my actions hurt it...don't know how others would read that. If offering information on the whole rather than the individual components isn't...

Todays update: Monday hooc 39.9v 12.5 mile ride ending with 37.4v Tuesday hooc 40.0v 12.5 mile ride ending with 37.6v Wednesday hooc 40.2 12.5 mile ride ending with 38v I found that if I disconnect the charger from the pack and unplug the charger from the wall…wait for thirty minutes and connect...

It quit raining so I went for a ride to check out my ‘bricks’ capacity today. Previously the battery would measure @ 39.4 hooc and I could ride @ 4.25 miles (not wot but with pedal assist and part throttle) before I would hit LVC and the battery would measure @ 25.4V. Today, after the battery...

yes the 40 AMP one, I have the 3 speed switch. Can I program to some value that will lower the potential high A draw when using the lifpo brick? and then switch to speed 3 or 4 when I use the Li ion batteries? wj

I don't know what to guess. wj

measuring with charger disconnected from battery I haven't broached that subject as yet...too many people say to charge for a week and watch the load, sun thing said to charge for several days. I'll give it a bit of time before I cut into it, if need be. wj

I'm going to wait a few days before I decide whether or not to cut into it, btw there is no obvious bulge or anything on any of the surfaces of this brick...if there had been I would already be there. The brick is in fact gaining almost .1v after a nights charging. wj

the charger puts out 45.2V and the battery currently reads 39.8V wj

Nukezero has been helping me out and I thank him. Rather than continue to impose on him to relay my story I’ll try to keep everyone updated. I have an A2B Metro that lost its built in controller last year. http://endless-sphere.com/forums/viewtopic.php?f=6&t=45907 I have been using an external...
