Hello Andy1865. All the best on your build. Good quality cells make the difference the bigger motor and battery make a huge difference when upon an incline.

Genuine 500 watt motor? Or one disguised as 500w, but is actually a 1000w motor. What ampere is your battery? I run 10s 13p on a 1000w motor guised as a 500w. Slow on hills 28kmh. If that helps.

A while ago I built 10s 13p pack using LG MH1 cells. The battery was built in several stages from 8p upwards. The BMS, an all in one type couldn’t balance such a huge battery and my want to fast charge eventual the pack went out of balance. Then upgraded the BMS, fitting a smart BMS allows’...

I’ve ordered from EM3EV, once and if I hadn’t seen a lot of posts and Youtube, info there website with no trading address etc, doesn’t inspire competence. A physical address maybe create more sales. Appreciate any company in China, that are buying from does the address really matter? Been...

Lovely build sure are seen on those dark roads. That controller appears chunky and robust how is it s performance on the bike?

Some LCD controllers have an absolute top speed. The LCD SW900 is 50kmh, no matter the wheel size the LCD panel limits speed to 50kmh.

If a BMS, was connected it will draw a small amount of current. Also if the battery was at a low state of charge or/and left for a long time include storage freezing cold then all adds to further depletion. The only way is to dismantle the pack and check the voltage cell by cell...

Maybe l’m a puritan never will I connect auxiliaries to a battery that does power a motor. Strict separation is my view. Volts for distance only.

Bought a charger from them few weeks back. No custom charge. Opened the thing up as you do and apart from the pub is glued into place, no stand offs, very well built, include a built-in mains power switch. As to the question only a buyer could answer. Photographs tell a thousand words...

Any more data on the hub, wattage? The battery most probable is sagging, although a voltage meter soon prove or disprove. If are planning on purchase another Ebike, another battery perhaps also requirement. Best to discover what the problem be with present kit. If it’s low quality cells then...

Far aware Risun are Conhismotors. Bought direct from them in past many years ago. Never kept their motors long always sold them on. No complaints.

Final got the voltages of each cell within two-three volts of cell two. Result was and after swapping out a BMS, with 5 amp charge, cell two now at 4.14 volts. Success!

Well, two in parallel 12 volt lamps worked a treat pulled the pack down to within 5 volts of the lowest cell. 2 amp charger and pack brought every cell up to 4.19-4.2 volts except cell two of since dropped 15 volts overnight. I disconnected the BMS, this morning and if cell two voltage does...

Ok, understood. Chao.

What sort of Ebike jimjay be of interest, custom DIY, or shop bought? I’ve a few tools include test gear specific to Ebikes, ever require. Include in the list a battery welder. Ebiking around this way is becoming very popular include the DIY, community of was always here the Bulgarians are...

Not at all just a ten percent flat tax rate. Laughs last, he. :)

Hello, jimjay and welcome from Yambol. Terrible roads huh, better this one? :) Tarmac was once here see photo. Are perfectly correct are many very good roads and plenty of interconnected villages via dirt tracks. The roads network here is very good and the quality of is overall satisfactory...

I’ve the option of purchase cell equaliser system, wait until the smart BMS, arrived, or connect some 12 volt lamps in parallel and drain two cells at a time. Latter idea cost about a couple of quid and the wholesaler was very welcome to sell old stock halogen lamps. I would prefer one cell at...

I don’t want to drain the pack just specific cells. Rather pull down all the high cells and attempt a balance charge from there. I’m concerned cell two maybe a problem within as it’s not improved it’s capacity, actual now down to 3.44 volts. While the other two low cells have at least...

Question. Anyone bled a pack on a cell by cell basis using a power resistor or 10 watt led? Bought a smart BMS, however, will need to wait least two weeks for its arrival. I’ve a 0-60 volt 10 watt led lamp on the bicycle and seen some usb power resistors 1-2 amp. Either of these could drain...
