I definitely like your equation to solve amps with no load I will look into this and try and educate myself prior to asking more questions thank you have a nice night
so would both of you conclude that amps cannot be measured with out a load using a volt/amp meter.
Thanks for every ones response here i am going to be retiring for the night, and hope to have a more clear understanding of this in the future
so more than likely here just tell me i am stupid for thinking my volt meter can measure amps ,not just volts.
Why do they put amps on volt meters if there is no way to measure them
thanks for your reply, It is a po4 and when purchased there rating was 60v/30AH fully charged at 73v.
fully noted i am a beginner i assumed the pack should measure near 73/30a fully charged.
Is this an incorrect assumption of the term 30AH.
And thank you for the rest of your input for what...
Hi,
I am a proud new owner of a 60v 30ah battery. I have upgraded from a 48/20.(both lifepo4)soft pack 1p.
I recieved the battery today and took reading of 67/22. That opened my eyes because that high of voltage should = higher amp on 60/30. Charger cut off is 73.5 and measures 24 amp no load...
I was recently repairing a 1500 Watt electric bike controller ,The brand is green time From aliexpress .
It has 15 fets I believe 3 negatives In 2 positives Per phase. After cleaning the area with isopropyl alcohol I inspected the surface and noticed What appears to be A surface Mount Bypass...
Using resistors in series , Can 60 volts step down to 6 volts.
If So what are the pros and cons And why would someone spend $50 or so For a step down converter When they could Use one or 2 resistors in its place ? :roll:
I have 3 of these controllers All the same 1500 Watts .I liked them so much I recommended it to my friend And hooked his up For him.I'll start by giving the my best answer to the original question of this thread.The controller defaults at 100% Without Using the 3 speed switch. You can over clock...
I have a 48-84 volt Green Time controller
15 Mosfet, 1500 w, 45 Amp Max.
My battery is 48 volt 20 amp hour fully charged at 56.1 combined with a 1000 watt 48 volt front hub gearless motor. The controller is about 5 months old. And the battery will be 1 year old in february.
This will be the...
Not to sound rude but I certainly won't be prying any tabs up to sacrifice the Integrity of a spot weld. Most people including myself don't have the equipment or skill and experience in order to get a good spot weld without overheating the battery
Just an update for anybody else that is reading...
This is not an inconsistent or sporadic connection problem. The voltage differences were measured from two separate ends of the BMS. The discharge and charge plug measure different volts and amps which is normally not the case when the BMS is functioning normally I presume the BMS stop current...
Today I was riding my ebike and wanted to test the mileage I was around 20 miles or so on one charge. Normal use for my 48 volt battery is between 51.4- 57.4 volts
Suddenly all power shut off and I assume the battery had reached its low voltage shut off. I was surprised because I did not...
I would like to run my motor in sensorless mode but I am concerned about overheating the phase wires.
Iran 14 gauge from Battery to controller but only run 16 gauge from motor Phase 2 controller phase
I have been checking the temperature religiously being paranoid too thin of wires and recently...
