well kudos to Lunacycle they are sending out another controller. I just hope it gets here in time.

We went and walked some of that area we want to camp and there still is over a foot of snow in places. Some patches are bare as well, nobody has driven in on the road yet I think my truck will do it. Hopefully with above freezing temps day and night solid for the next week it will almost all disappear. This has been the longest winter in some time, snowpacks are almost 200% in some of the drainages, there will be some flooding for sure this year.

The controller was not the issue, it is the battery's BMS tripping at about 3-4 amps (it should be good for 70). The controller was just self limiting to 5 amps which gave very similar symptoms. My problem now is I have to front the expensive return shipping on the battery and no new battery is coming my way from Luna, they just plan on refunding my battery purchase and then I'm on my own to find another. This whole process will tie up any money I have to buy another battery for weeks, not to mention waiting then for that to ship. Because they sent me a bum battery the whole project is taking weeks and months rather than days. So I redact my kudos to Luna at this point.

Any idea if it is tripping for legitimate reasons (cell voltage drop) or if it think's it's hitting it's current limit?

If the BMS is the problem - not a bad cell - you could replace the BMS.

Except it was brand new, never used and the BMS itself sells for $100. I would happily try and fix it myself if they sent the BMS and sent me the $100 all the shipping they are going to have to refund. In reality if I spend over $800 on a new battery it should work at least for a single ride. I was hoping for 1000 charges but didn't even get one.

That's an odd experience with Luna Cycle, usually they have pretty good customer service, and a battery that didn't work right as received should get a replacement.

Well I shipped it out today at $38, if they refund everything I will buy another battery from them. It's possible the battery I had wont be sold any longer as it was "on sale" and is out of stock now. They didn't offer me any other choices for replacement, overall their tech assistance boss is pretty short with the emails. I described what I experienced, did whatever tests they asked for, even videoing the results and sending that. I just want a bike kit that works after dropping $1600 total with Luna at this point. I understand this stuff from China doesn't always work 100% first try out of the box so I have patience assuming they keep trying to make it right.

Now fedex wont even take the package back with new postage packages led and labeled exactly as it came to me. I'm starting to worry.

Well I finally got my battery refund last week. Took long enough but at least they refunded the current price which is higher that when I bought it and all my shipping. So now I can buy the same 60V battery at the new higher price or go with something else which I think may be best. My only concern is I bought a $100 charger based on the 60V battery. If I go with a 52 or 48 I either need to return the charger, which I'm tired of returning things, or I think I can open up the charger and change some settings to get a different output voltage. Currently (LOL) it's 67.2v at 5 amps and I think cuts off at 95%. It's a KP400A charger. I would rather have a 52 or 48v battery. Anybody know if you can change these things? I think I'd rather have it cut off at 90% as well. The company that sells it from China lists all possible voltages from 12-60v available with this charger https://www.alibaba.com/product-deta...539687624.html
According to some other videos similar chargers have 3 pots inside to change all these settings https://electricbike.com/forum/forum...i-and-advanced
I guess I just will open it up and see what's inside.

When my charger started giving me issues/I got tired of how slow it was, I started looking for alternatives. What I found was mostly sketchy Chinese chargers that were likely to die after a few months of use. I bit the bullet and bought a Cycle Satiator. It'll charge just about anything and should last a long time. There might be better options on the cheaper end now, but when you factor in the flexibility, the Satiator can be well worth it in the long run.
