The black cluster will all feed off the battery ground/neg. No earth as the voltage is DC, only + & - used.

Usually grease making the pawls/springs stick. A few ways of trying, a recent issue with a Pendleton ebike on here was solved by trickling a few drops of oil in to the freewheel workings. Read this recent thread...

Pawls on rear freewheel stuck not engaging.

Now we can see better there are only ten sense wires so all are v+, you can probe the rear of the wire. Use the battery gnd for black probe and move your red probe along each wire and write down the voltage reading, reading will go up incrementally. Post results when done.

Going back to one of your initial Q's in another thread, range!!! As you can see rider weight has a lot to do with battery capacity usage, same route same hills and conditions. On longer rides swapping batteries is an option if they are the same fitting otherwise for your self a second one may...

d8veh no longer exists on here, he has gone for good deleted his account :(. His last project was a wireless (almost) ebike but sadly looks like we won't be seeing any pics.

30B are high voltage 4.3v cells pretty rare in ebike use because of the need for a different charger voltage. The spec states 60 cells and 2.6ah so you have a 10s6p with 2600mah cells configured inside the case. The actual ah has been rounded up to 16ah but the battery is actually 15.6ah or 561wh.

What you have to learn or realise is that you can't expect 10/15a rated cells to deliver both high amps draw and max range, it's a trade off of either one or a compromise of both esp with 4 or 5 P configuration and 3 - 4 kg battery. If you want more of both then you need a heavier battery which...

Your battery is using Samsing 2600mah cells either the 26F,26H or 26J variant, in themselves they are mediocre cells but if as stated there are 60 cells inside then they are configured for 6 in parallel so have max 31a draw for a short period so will be good for 15 or 18a controller setting. The...

Battery capacity is ah or wh , controller rating is straight forward amps not ah. Battery cells have a known capacity in mah. A 3000mah cell is 3ah, these will be connected in parallel. If 5 cells are used then this gives the battery its capacity rating which will be 15ah or 540wh at 36v. It is...

It appears the new B versions are throwing up error codes adjusting amps to high, to go 18a you will need to buy the correct rated controller. The speed is probably limited in the software under PAS tab or throttle tab, often it is set for ' By display command' but also may be set at 25km/h...

Hello Martin and welcome seems know one else is greeting you today.

For high amp and value the 20a rated LG he2 is a very good cell though is only 2500mah.

Gringo's loaded he has one bike for every day of the week and two spare just in case of mass breakdowns :p.

A very simplistic view and reply when in reality most peeps won't have fluid, syringe and tubing to start with.

30 odd mile round trip for £15 is fantastic value for a mobile bike mechanic to do that job. If they are Shimano then the mineral itself isn't cheap. Keep him in your pocket Gubbins for the future. Even worth a mention of his name and contact on here as others in the area would most likely use...

VTC6 for the increased capacity and a solid 15a continuous rating more then enough for 4P config. Review of the two cell from 2 different independent testers. https://www.e-cigarette-forum.com/threads/bench-retest-results-sony-vtc6-15a-3000mah-18650…a-fantastic-15a-20a-battery.846895/...

He probably did at the beginning but later on I believe his views were that it was trying indoctrinate readers with the views held and shouldn't be the main topic of a e -bike forum. Although it is in the charging post, in truth if peeps want to do politics then join a political based forum and...

Have you tried changing P2 setting for freewheeling, try 1 or 6 to see if it works.

Any setting changes you make may alter the other assist level settings so before making any change make a note of all parameters in the advanced screens. In the P settings look to see if P3 is set for 1 or 0. This setting is for PAS mode, 0 is for speed control and 1 is for current control. 1 is...
