large diameter rear hub lace

bicycle rims spokes

sucks

almost always added dish

sucks worse

nearly trouble free rear hub motor

moped moto supplies

trade off

expensive heavy no rim brake

everything connected and powered confirm 5v red to black next measure voltage from each small colored wire to black ground turning wheel slowly do the voltages change as rotated disconnect everything motor rotate freely no wires touching now try touching each thick phase wire to another motor harder...

asked for references job photos

ignored

spamming forum is getting old

what he said

maybe open controller

check if 50v caps

if so may work fine

other than lvc

dumb idea

some folks ride 20wh/m

most dont or won’t

cell age ambient temps

terrain wind soc

use of legs desired speed

all contribute

good luck

what i say 3077 doesn't really matter look it up yourself no probing shunt insert amp meter between battery controller spin wheel off ground should pull around 2A many multi meters handle 10a less accurate simpler just estimate 2a wheel off ground adjust ca shunt based on that estimate have a nice day

fully charged 18s

ragged edge v max 3077

of course load will drop voltage

do you feel lucky

measure battery amps

small amp load fine

spin wheel open air maybe 2a

or simply rig dummy load

adjust ca shunt value to match

external amp meter measurement

future reference jot down

many variables estimate voltage vs % remain differences between loaded and resting voltage measurements cell chemistry bms oddv numbers from my ass 16s pack around 46 48v loaded minimum it should probably go soc voltage roughly between 67 and 50 52v resting if linear usually not careful discharge me...

in your other thread

i say worrying about nothing

enjoy your nicely built ride

3077 will tolerate 16s 67.2v

up to 75v no 21s

calibrate shunt value use external power meter

250 lb rider

front fat tire 10-12 psi

rear fat tire 12-15 psi

soft comfy ride quality

no complaint or problems

dunno any rating

25 30 mph is about as fast will cruise on 4 or 5 inch tires

have touched 35 downhill and all seemed fine

fairly noisy at higher speeds

1000s miles on many bbsxx drives no faults practical power limits much different than hub motors apply hub power applications and suffer failures observe continuous power rating trouble free service rear hub motor very weak imperfect bicycle wheel troublesome to repair spokes flats tailored for only...

bbsxx use sine wave controllers

hal blaine rip....

no previous mention controller

suggest t10a100l for 10a charge

schottky if you want

not what i would use

understand nominal battery voltages

lifepo4

3.2v nominal

3.65v full top charge

even your charger description states 6s

3.7v nominal 18650 full top charge 4.2v

bms seems likely

agree open battery to verify cell groups

motor controller compatible

8s life need charger capable of 29.2v

6s 25.2v charger not compatible imo

not fan of schottky for job

p-n cheap and durable t10a100l

charge current determines max amp

do not cut leads when pushing amp limit

meanwell cc cv power supplies

bulk plus occasional rc balance charging

always safe fireproof location

further convenience add small bms charge only

large diode in series will drop .7v
