Sucks about the camera, but at least you can get a really nice one for cheap these days.

The only thing I noticed was the power meter seemed ta be giving "hokey" readings

Why are (do I think) the reading from the Power Meter "hokey"?

Well, let's establish the specs (of the components we are working with)
...& then, maybe expand on the discussion

So first, I went back to the Sequoia build thread (my digital notebook)
...& found some specs, on this battery pack that I posted, when I first got it

52V 20Ah with 30A/40A BMS Lithium Ebike Battery for 200W~1500W Electric Bicycle Motor

• Voltage：52V
• Battery Capacity: 20Ah
• Energy: 1040Wh
• Configuration：14Series 8Paralles=112pcs cells
• Item Length: 260mm
• Item Width: 70mm
• Item Height: 160mm
• Item Weight:≈5.6KGS
• Standard charge Current: 2.5A
• Maximum continuous charge current: 5A
• Max Continuous Discharge Current: 30A/40A
• Peak Discharge Current：90A/120A
• Charger Input：AC 100-240V
• Charge Cut-off Voltage：58.8V
• Discharge Cut-off Voltage: 39.2V
• Charger: 58.8V 2.5V
• Speed Controller specs:
  • Model: YK-31
  • Power 1,000W: for use with a 1,000W brushed motor
  • Output Voltage DC48V: for use with 48V Direct Current systems
  • Current 28A: can output up to ~28A
  • Short Voltage 42V: controller has low voltage protection circuit
  • * Which means, the controller will "shut down" when the voltage in the battery pack drops below the preset limit of ~42V
  • Throttle Voltage1-4V: the controller is compatible with throttles that have a 1V-4V range
  Motor specs:
• Model: MY-1020
• Voltage: 48VDC
• Rated Current: 26.7A

Um...just got a "call" BRB

Hey T,

Evil f'n artist sounds kool
...but, the EA program is "geared" towards kids/students
...so, we'll have ta save that, for another project (maybe the Morgan)

Fine, go poop.

Hey Denny,

Kinda reminded me of: "Hope ya had one hail ofa hell of a piss...Arnold"

I switched out the 50A Shunt, with the 100A Shunt (that came with it)...just to see

Yup, for some reason (should have worked fine) the 50A Shunt wasn't co-operating with the meter (it came with 100A Shunt)
...so, I took 'er apart & did some investigatin'

Ta do this I had ta remove
1.) the battery pack,
2.) the seat
3.) the wire strain relief clamps
4.) the insulator sleeve too

First, I double checked that I had the wiring/connections correct

Yup, everything seems fine
White wire on the P- side of the Shunt (to controller)
...& Green & Black wires on the B- side (to Battery pack)

So/then, "to see" if the Shunt was the issue, I switched/changed 'er out (50A out & 100A in)
* Had ta switch/change some of the terminals too


Back in Business

Now, just reverse procedure
...ta "put 'er back together"
