Thanks again. I have Now soldering off all wires and will take the bms to my jobb. There i have a elektro lab. If i am Lucky we got the right mosfet in stock. I have tryed too find scematic drawings on pcb board, so i gess I have too do it old school. Resoldering/ touch up critical components...

Is There some of the smd components Who need a extra check on bms board, like a transient diode or simular component ?

Tryed it, no change. Have soldering it off again, Then i try to connect B- then insert balance wire connector, then charge plug and at last powering charger. Other sugestion ?

Thanks again. Then I will soldering it off, an then soldering it on again after 5 min.

Thanks trex. Now all are between 3,51V to 3,57 V. Charger push 41.3 to the bms, but no charging. Normaly charger goes from green to red on led, and goes green again when fully charge. Still need a good trick too make the bms accept charger. Maybe bms has some other problems. Have no technical...

Hi I have Tryed to fix a old bottle battery. I have replacing 4 cell. There are 40 battery in 10s 18650 2 ah. I have used same cell size on replacment cell. I have charge the 10 cell pack induvidial up to 3,1 to 3,5 V. I have ca 35 on battery pack. When I try to charge it, The bms will not let...

Yes. I use 2 multimeters. 1 fluke187 and 1 tes. 1 on output and 1 for test. Change place on meters after first test round. Same result. The 2 meters Was giv ing a blury/pulsing result. Tryed Even to set it on ac because of the wobbeling of detection volt. Now I have bought new hub wheel...

This is an old motor YU CHENG SWX190-3B09 orginal powered by Pb-acid battery. When breaking motor generate power backpack to battery. This funktion have I removed when in instaling lifepo4 battery pack. Hub motor generate power on 3 phase wire. (Forward and backward) Testing hall with 5V I get a...

Greate. I have 5 km climbing up in the forest, so 25kmh is more than enough. I gess that my speed is aprox 6-12kmh. How can I controll check the hub motor without working controller ? I want to check it Before purcasing new parts. ( I work as a Electronicer with soldering/pcb andhave a lot of...

The understanding of Norwegian is posted over. I have a 15A limit with my bms. So I think that the s06s controller will be fine with the 14A limit. Full charge on 12 headway is aprox 42V. With load I gess 36-38V. Losing power in controller aprox 15%. 36 x 14 x 0,85 = 428,4W The hub motor have...

The 250 legal nominal watts is the mechanical effect which the engine will be able to provide continuous for one hour without the temperature rising more than two degrees above regular operating temperature. Although a legal motor may only provide 250 watts nominal, it is completely legal that...

A switch or button for override the 250W limit . I will try to translate the Norways EU Law understanding in next reply

Thanks, I will do that. I have read the manual for lcd and controller and could not find the button/switch for short time boost. Do I need a another controller or lcd for get that function ?

Greate. Is it posible to soldering a smd or normal fuse holder on that spot, or take som wire to make fuse on outside ?

S-LCD5 LCD METER (17.33$) S06S 250Watts Torque Simulation Sine Wave Controller (24$) Ten poles PAS--Pulse Padel Assistant Sensor (2.7$) speed sensor (1.9$) Ok prices but shipment Was about 35$ so maybe I have to pay costoms. Will this setup give me the extra power in hill climbing ? What is the...
