No need. If I recall TUFKAD's previous avatar correctly, he's an android.

LiPo packs have balance plugs that provide a connection to each cell. A custom harness using JST-XH balance cables lets you connect them to a BMS in a similar manner to any other lithium pack. In fact, it's arguably easier than most other BMS installs.

Yes you can. Using LiPo packs doesn't preclude you from using a BMS. No point of using LiPo if you don't need the power density though. EDIT: Sorry. I just re-read the post you were responding to and missed the OP's dismissal of a BMS.

Or possibly a short inside the sensor. Have you continuity tested the 5V and signal PAS sensor wires?

^ This. The PAS sensor LED is permanently illuminated because it is being backfed a voltage through the signal wire. As Neal states, either you have the 5V & signal wires connected the wrong way round, or there is a short between them somewhere.

Have you tried swapping batteries?

The battery is a 35E 5P pack - not ideal, but should be able to manage the odd bit of 35A drain. The BMS isn't cutting off power and the fact that the LCD display never shows more than 800W makes me believe that something else is amiss.

An obvious point, but have you tested this with a fully charged battery? Can you check what custom parameter 'P14' (current limiting) is set to on the LCD display? Finally, does your LCD display allow you to access custom parameter 'P17'?

Hi Are you able to post a link to the exact kit you have purchased?

While that's certainly true when it comes to 'emergency' braking, the huge majority of braking is done with lots of time to prepare, e.g, slowing at junctions, hill descents, stop-start traffic, etc. This sort of braking doesn't require an abrupt speed reduction, so doesn't cause loading of the...

There's no need to have the hub on the front. In fact, a rear hub has the potential to provide much stronger regen since you're able to mount the motor much more securely.

This is definitely true from an energy recapture perspective, but overlooks the even greater benefit of regenerative braking - almost zero physical brake wear & maintenance.

'Self-charging' (regen) is already realistic, but only if you're already committed to a direct drive motor. At that point, everything required to implement it would be present, so would be silly not to.

The person in that video is a moron.

But that's exactly what regenerative braking is. Engage and pedal and you've got a 'self-charging' bike.

What a load of nonsense. 'Self-charging' ebikes are nothing new (a nonsense concept in itself) and regenerative braking is as old as the electric motor.

Other images show the bike with pedals, which I assume have been removed in the above photo. Is there anything else that would cause it to fall outside of EAPC law? EDIT: Scrap that! I don't think it has any pedal assist functionality whatsoever, so would need a controller upgrade in order to...

Other that a 'twist & go' throttle, the bike looks UK legal. Why not just disconnect the throttle if you're that worried?

A controller powering a motor in 'torque' or 'current' mode will always spin it at full speed without a load on the motor. Any video demonstrating otherwise is showing a 'speed' controller. To solve your backwards peddling PAS issue, tty setting custom parameter C1 to '5'.

What PAS sensor are you using? What is the model? How many magnets?
