Yes exactly.

Woosh is your most likely place to shopfor a 48v kit or there was one other UK seller but the names passes me by for now.

If not in to diy then yes sell the bike and get a working bike , but not a carrera or halfrauds type bike. Typically a suntour based carrera bike is the last candidate one should consider to covert with a replacement system, it can be done if you are capable . The only plus is you already have...

Why does he need to change brakes ? With a KT set up they aren't needed.

There have been three or four folks on here who have gone down the upgrading route, use the search feature of the forum to find threads.

The module you speak of , will be the display and likely well over a £100. With carrera past history one will be better to spend £80 -£100 and buy a complete new control system and ditch the TS system. If you are handy with diy and a soldering iron then buy a dual voltage 36/48v KT controller...

Like ES , here we are a community who try and help or solve issues when folks have a problem with there bikes. Typically very very few so called LBS have the knowledge, skill to understand or lend time to repairing a generic hub type bike, Hub type bikes being the biggest seller of all...

It's only a 2p pack so depends on the cells used and the previous users current draw dependant on the cell discharge rating. It may be a bit abused/knackered or as you say may not have been balance charged properly , only time will tell once one can get it to balance charge. I use 12s 2p...

Saneagle under another guise was a well regarded knowledgable poster/contributer on ES so one will simply have to fold that jibe up in to his pipe and smoke it.

The Hall is just a switch is should pulse on/off as the Hall senses a magnet passing. A solid led suggests you have it wired up incorrectly or there is a wire short. Show us your wire sequence /configuration for the PAS connection. One can test the PAS with a meter , probe the back of...

Current doesn't limt the max speed it does limit the max watts output for the motor, typically that bike will produce approx. 370 - 400 watts max from the hub motor. Speed is limited by ; 1. Motor RPM winding. 2. Voltage. 3. Any system restriction whether wiring or display . A battery has...

It is a basic speed control system, Tianjin Santroll are a very common cheaper OEM system used . There is no speed adjustment as the three speed control levels are pre set to approx. 8 ,12 & 15.5mph in each level and will give the same current/power in each level, only the speed cut off differs...

As mentioned the only wires to concern yourself with are the pair of battery connections to the controller both usually a bullet connection. The phase and Hall connectors and any other wire connection have no relation to the battery, they are merely housed within that front section to hide...

One would think KT PAS 4 is the % of assitance you have been more used to Peter, so you maybe should try PAS 3 more often so you still generate some input effort . For me I ride very flat terrain and 99.9% of the time ride in PAS 1, tbh the only time I have used PAS 3 - PAS 5 is out on my...

KT PAS level %'s are very different to other PAS levels found on other bikes. PAS 1 13%. PAS 2 20%. PAS 3 33%. PAS 4 50%. PAS 5 100%. Yes with KT one will be putting more effort in esp on the first two PAS levels.

It is not only the 4.2v cell group that is the issue, the pair at 4.1v will also act the same . If one were to discharge the 4.2v and not the 4.1 v then once they also reach 4.2v ahead of the othe rcell groups , said BMS will cease charging as any balance will still be too far out. One will...

Current can and does make a difference but that doesn't explain the range difference between your wifes battery or your battery, typically if using only PAS1/2 then one is using a third less current then the wife so there must be other factors in play. The Lishui is likely speed...

They are ok with an arc or small curve along the routing. For a folder opt for a rear rim brake if in doubt and a front HDB, the front is where the most brake force can be applied and controlled and typically the front accounts for 70+ % of braking effort . Can a fold be managed with without...

You guys who like playing with fire and this is not the only time it has been mentioned or tried on the forum. If you want to carry out stoopid techniques then carry on, if you are lucky you may have the kudos of being the forums first recognised battery fire. The BMS is fitted for a reason...

There is a cell group at 4.2v so the BMS won't allow further charging as the other cells are too far out of balance. The pack is out of balance , the BMS won't balance such a large discepency of voltage. The 4.2v cell group needs discharging down 3.8/3.9v as do the pair at 4.1v, the 3.6v...
