Thanks Dado
It looks that I will build my own battery. Can you recommend bms (which will work with bafang system) with can bus so I can see % on the display?
Samsung 50E have about 35mOhm of internal resistance so about 70mV at 2A discharge so 3.3V a cell looks like a waste indeed.
Tomorrow...
Charging problem - a bit of the update, drained the battery to 3% left. Battery not charging, charger outputs 49.3Vdc for a 2-3seconds and than turns the output off, green light stays on. I checked the cables yesterday and they are OK. Error code 09 stored in display diagnostics. Looks like BMS...
Battery is 59% charged at about 5Ah 45V (about 3,77V per cell) . Full capacity is 9Ah and charger voltage is 49.2V so I think it should topped up normally. Will see tomorrow.
Edit
Just wondering if there is any build in fuse in the battery or charger.
Today I had to remove the motor to check all connections (have some not charging issues) and found that the front bolt holding the motor have a bad tolerance on non drive side, as a result motor was not secured properly + hade some loud click noise every so often. Pictures will tell more than a...
Hi. Got a bit of the problem with charging of Btf014 battery. At the moment it is 59% left @ 45V, when I plug the charger in, it does not go red(charging), lights up solid green instead (like fully charged). There is no faults in diagnostics. Just wondering if there is a voltage threshold that...
Small update.
Fenders are on --> RRP Mudguard
Headset replaced with acros is52 - fits nicely, cables are well sealed, there is also more room for them because inner diameter of acros bearings is larger than the stock ones. There is extra seal at the headset top cover and fork race (well...
Yes, pivot bolt is drilled and tapped with M3 thread. Sensor must be sanded down a bit to fitt in. Sensor cable must be extended about 40 to 60mm. Now the ori big magnet was causing erratic speed reading when wheel was spinning slow display was showing about 65km/h. 3mm neo magnet is working...
A bit of a test ride video bellow. Done about 120km so far, first impressions are very good. Have a few minor upgrades to do and the bike will be finished up 100%.
M820 --> light output 12V 500mA, question there, is the output constant current type (like LED driver) or rather constant voltage 12V with 500mA over current protection (power off when protection is active) ?
Thanks
Battery is 410Wh bafang BT014. I have used light stuff whenever I could. DIY wheelset did the job. I think, carbon rims, carbon cranks and DIY battery can save further 0.6kg.
Hi
I have ordered LCE930 frame in March and finally got all bits and pieces to put it back together. Bike came out at 18.65Kg with no pedals.
Had some minor issues during the build but got it sorted. M820 motor had 36V firmware instead of 43V, got helped and managed to flash proper one.
Most of...
OK have a firmware. Just instruction is not clear.
Can I update firmware via interface connected into the HMI display or have to remove motor and plug it directly to the motor itself ??
Hi
I am in process of assembly of lce930 with m820 motor.
I have ordered 43V motor and the battery kit.
Is my firmware 36 V version ??
Another issue I have, battery level indicator stays at 36% after a few hours of charge.
The charger green LED stays ON solid when I putt the plug into the...
