Jeez, affordable is based on its value to a customer. To you apparently not, but to many other ES an invaluable tool. Some of us aren’t nursing $300 batteries and see a return on our investments. All good just different values.
Not unusual. Chargers were my worst nightmare working for one kit and battery seller. The most service calls ever on a single product, period. I spent $250 on chargers before a Satiator. I’ve only spent $20 on two cheap fanless as emergency backups since. So it’s now been 4 years and it still charges 3 different voltage batteries at programmed levels. for a serious rider whose invested significant dollars it’s a great value.
my question was the voltage.. 36- 48.. I don't think you mentioned it... and double check the one you think is dead,,sometimes cheap switching power supplies are touchy (try plugging battery into charger , then powering up power supply. ) ...( I have seen some new switching supplies that are DOA / off specs, and some RF noisy..)
Really a must have! Good post!
lets agree to""just stop..."""Giving people wrong or bad advice"" " I have much experience ,,I worked in a few bike shops, motorcycle shops, I have knowledge of electronics and computing.. ..If you think 300 is not high end for a transformer excuse me... Like I said the BMS does all the heavy lifting ,, and yes I could get a charger for 700 ...the fact is a slower charge is better and you don't need a $300 charger for that... for most consumer battery packs.....Look I don't want to debate.. so lets agree to just stop. Giving people wrong or bad advice as you say...
Well indeed a BMS MIGHT provide SOME of the functions, but all that experience isn't coming into play in this thread.
Great, but you can expect that there will be times when someone will call out misinformation. There are a lot of great folks new to eBikes here. FeliZ and others have DECADES, like 5 or 6 decades (50-60 years) of experience on two wheels. Several here are also engineers, well beyond my skill set. As I wrote above, implying and in your case claiming a BMS is the end all in battery management is actually DANGEROUS BTW.I have a couple of BMS in my repair/build/spares box
that's a nice collection of bms's ... they must be important..for you to amass such a collection..
The Grin charger is programmable and I charge 24 36 48 and 52v batteries with one charger. Those Kingpan from Luna have high failure rates. I used to cringe every time I got a support case. And they were a daily event. I use $10 AliExpress fanless as backup chargers.
Most days I find this the kinder gentler forum. A core of curmudgeons willing to share and assist. All out of passion from the day we took the first EBike cruise. If you moved to ES you’d quickly discover I barely know sh*t from Shinola. What I do have is a passion for reading and the self funded, “TJ tries every style of kit.” Scores of mistakes, miles of learning the differences and the outcome a fascination with eBikes,

yes, I want to find a flat foot frame with a motor I’m curious about. The Yamaha. I’m unable to ride conventional frames. Limiting my choices
@Feliz you have been instrumental in helping me fix some of the initial nagging build issues. Particularly the Rohloff wiring. Thanks to you I was able to isolate what I was doing wrong and have since significantly improved my ability to build and deliver quality bikes.
Some of my customers have told me that you have been very honest with them, and I have a great story to tell about my learnings since then. Thank you for helping, being honest, and most importantly providing constructive feedback. I could not have grown as much without some fairly brutal feedback at the very beginning
Thankfully nearly everyone since the first time has been happy and has commended by ability to work with them on building a much better bike.
Thanks again.
