As already mentioned simply removing said battery to recharge and then reconnecting said charged battery should have not affect the bike working. 1. Have you or can you double check with a meter that the battery is in a good charged state ? 2. a, Is a throttle fitted ? b, If so does this work ...

The best level to recharge is the nominal voltage or voltage it is left at, nominal being 3.6 - 3.7v. If you are using the bike regularly it doesn't really matter but once you get to 50/60% it depends on your usage/range, it may be more critical depending on the battery capacity and intended...

The OP would need to monitor the battery voltage so it doesn't drop below 41.5v, one could try and rely on the bms to cut but unless voltage is monitored one could be stuck miles from home.

A good alternative if one wants to covert to HDB's from rim brakes, saves a new bike frame.

Your hub is a Direct Drive model although it has a restriction between 250w and we assume 1000w it probably has winding of about 390rpm or so. In a 26" wheel that might equate to around 30mph at 36v/ 22a, at 48v the rpm will increase by some 33% to over 500rpm that in turn would equate to about...

BMSBattery in China sell a Lishui controller with display cost is $38 plus postage, one can't readily buy them otherwise as in the main they are OEM only. Whether all the connections are correct only you will know by comparing both items. Lishui work with Kingmeter displays but often they have...

An option that is not cheap. Tilting 3 wheel reverse trike a new build | Pedelecs - Electric Bike Community

There comes a point where to many amps x voltage will be add to much heat for the controller to handle, the mosfets will be heat sensitive with a max temp range. At 36v/22a the controller will typically give 792w at 48v this jumps to 1056w, the components in the 36v won't be normally...

Here it is. Bike Frame Conversion Kit Bicycle 160mm Disc Brake Adaptor Bracket Holder | eBay

It is all about programming and compatibility and branding. SxxB controllers are China brand Brainwave . KU are Kuenteng but only analogue led or 3 speed compatible. KU93/123 doesn't use a display just a switch 1,2 or 3. KU95/125 are led only. SxxP & SxxS controllers are Kuenteng digital...

Should you need a new different controller you HAVE TO/MUST buy a compatible LCD display as well otherwise the bike won't work.

A simple test without measuring to tell if the controller is faulty. Leave every thing connected, no battery power. Lift the wheel and turn clockwise does it free wheel easy ? If severe resistance is felt then disconnect the hub motor cable and try again, If it frees up then controller is...

If after carrying out the test listed by vfr and controller is faulty, then use the link/s below for new controller kit. These two controller kits are about $80 with cheapest p&p, one has to select the added components need form the drop down boxes. lcd3 display is the best decent one or the...

For the Freego you only need a 15a controller kit but it won't hurt to get the 17a kit for just a bit more pep, 17a will give nearly 14% more power. A plug and play diy kit form China only needs two wires to be usually connected by the end user and may need a different connector if not...

For a diy kit it's a no brainer to buy direct from China source for half the cost. The £185 kit is KT/Kuenteng I believe from another post about this kit, one can buy the same kit for about £70 - £80. For your money you get controller, lcd display, throttle, PAS & brake cut out if needed. To...

With ebikes there are few standards in electronics, the few standards that will be found is in China hub motor ebikes. Hub motor wiring is pretty much standard, I have four different branded hubs and all are the same. Most use the same water proof motor connector whether Bafang, Mxus, Aikema...

A 11.6ah & 14ah battery can't use the same size mah rated cells, the 14ah would have to be 14.5ah then both would use 2900mah cells. 4 cells in parallel for 11.6ah is 2900mah cells, the 14ah battery will either use 2800mah or 3500mah cells depending on how many in parallel. The cells may be the...

We ned to know more about the new battery, a link to the product preferable. Critically as vfr has said it depends on the cells used in the battery and your controller max current rating. With top quality cells one can get abut 25/30miles in low power. My lightweight small 24 cell 44v battery...

The price of 185, I agree is a stupid inflated price but I guess if they are doing the work they have to make a profit somewhere so a big mark up on the parts is expected plus labour. We shouldn't really be surprised though as there aren't many options open to have this work done in the open...

The pickup/ signal may be down to the crappy programming, my KT's are verrrrry good . Signal/pickup is excellent as is PAS reaction of abut 1/8th rotation.
