Please don’t worry. Nothing is end of life. You can see the situation as following: current generation Metr Pro modules are out of stock. But they are perfectly capable and those who managed to grab them recently for the price, that hasn’t been changed for several years are actually lucky.
New generation hardware is currently being worked on. We now have the prototypes that we will be sending to select beta testers any time now.
The software is compatible with both current and new generation hardware. In fact some people are still using HM-10 based modules that I sold in 2018 and those still work! (apart from uploading the records)
Let me know of you are still looking for testers, been using metr for years and years, would love to help you guys work out kinks and stuff! My mtb is still running metr + davega, which I think is the ideal board setup.
Running 10s4p are there spesific settings for Hub motors, right now metr is maxing out at 30kph and not going any faster - should reach 55-60kph on the bench.
I suppose your drive settings are incorrect. For a hub drive you will want to have “Motor pulley teeth” and “Wheel pulley teeth” set to the same value in Settings > Motor. That way the gearing ratio is 1:1.
this is helpful, whats weird its a 10s4p pack with 1s dead.
when set to 18 the motor reachest 50kph, when set to 20 reaches only 44.7kph. could that be the battery settings at 9s casuing the loss in speed since the true speed with 10s should be 50-55kph?
Actual speed is dependent on voltage, kv, gearing and wheel size, provided there is enough power in watts to get there. You can do the math on the esk8 calc at the top of this page. This means a fully charged battery will have a higher top speed than a partially charged battery, and it’s a fairly significant difference.
The pole setting is just how the vesc calculates motor rpm, which is needed to display an accurate speed, since it only knows electrical rpms. So if this value is adjusted the vesc tool will show different speeds, but an independent gps app would still show the same speed provided the battery is at the same voltage.
More concerning is the battery with “1s dead”. What are your p group voltages when fully charged? How about when empty? Is the discharge bypassed and will it get over discharged by relying on a vesc cutoff voltage that assumes a pack with a balanced p group? How did 1s die? Is this battery still safe to use and charge or is it a fire waiting to happen?
well 9 groups are balenced and 1 is dead down to under a volt. the battery was still 38.8v fully charged rather than 42v. but normally when on the bench top speed easily was 50kph… weird that it goes from 44-50kp from wrong pole settings since the correct settings on the rotor are 20… tried even setting the motors in config the same way.
you say that after like 3 years that the packs been 9s without much concern to surprise it’s a raptor potter pack. guess some of that raptor stuff did last long. still never figured out what killed that group i suspect the bms
