    60v 30ah brand new battery

    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

    60v 30ah brand new battery

    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

    60v 30ah brand new battery

    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

    60v 30ah brand new battery

    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...

    60v 30ah brand new battery

    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...

    surface Mount bypass capacitor

    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...

    resister

    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:

    Greentime Controller high top speed

    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...

    BMS- LVC

    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...

    BMS- LVC

    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...

    BMS- LVC

    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...

    Sensorless versus Heat

    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...

    The ultimate torque arm (For <2kW and standard axles)?

    $15 for a set of two when you buy a pair of training wheels with these brackets included at Walmart or any other store these are way stronger than any other torque arms you'll find on the market secured with a u bolt that goes around the fork. No need to wait for shipping. And only about fifteen...

    2.5 amp charger

    I have recently blown a few Chargers due to the polarity being on the opposite sides of a one way plug. So I have bought a resistor kit to fix the Chargers After fixing I wanted to check the output voltage and amps to ensure proper use because I used a .33 ohm resistor which should have been a...

    Water shorted throttle or bad controller

    It seems I am having a throttle problem today I went to go for a ride and noticed it at been raining as soon as I got on my bike I turn the power on the throttle and I believe the bike immediately wanted to take off without twisting the throttle so I powered it off and pulled the brake got the...

    Front hub thousand-watt bad

    Thanks so much for explaining to me how it is converted to AC I am located in Oregon USA we have 1000 watt Max regulation I'm pretty sure this is a direct drive unit there are no gears at all and it spins freely motor powered or not powered I do not know for sure that the controller has fried...

    Front hub thousand-watt bad

    I'm confused about these three phase electric bike motors they refer to them as having three phase lines does this mean they are utilizing a 3-phase current. If so how does this work everywhere I've looked online three phase systems are only used in AC applications from what I have read DC could...

    Front hub thousand-watt bad

    The gas motor does 31 miles per hour The electric maxed at 28 miles per hour Are you saying that if I only had electric motor I could fry the Fett's in the controller by simply going downhill at 35 miles per hour? how is this possible that seems like a poor design I'm having trouble finding the...

    Front hub thousand-watt bad

    So yes I originally thought the short was in the wires right as they come out of the axle I put the motor in a stand and spun the wheel there was no resistance I then shorted the three phase wires one by one and the resistance immediately came back I was surprised I thought I had a short in the...

    Front hub thousand-watt bad

    I have a 48 volt thousand watt front hub brand new to this electric bike thing spent last year with gas bikes last week I noticed I wasn't getting any power to the motor but the lights came on the throttle after doing some research I noticed it was a lot of resistance in the front wheel. After...
