Cells will take all day for each one with trickle charger . I use an old 5v phone charger for charging low cell groups via the BMS sense wire white connetor block at approx. 1a , it will take about 20 -40 mins on each cell to get them up to above 3.1v. Cut the charger jack off and solder an...

One can use any 250w hub to get 2kw out of it , it will mean over volting and higher current of 35/40a but the important bit is modiffing it for cooling . It appears expensive but ferro fluid seems to be just the job. As I have mentioned before over 2k from a Bafang swxk 250w hub with ferro...

If all the ten cell groups are all at 2.7v then the BMS won't allow charging, 27v is too low for a 36v battery . Typically 30/ 31v is the lowest one might see. The BMS is seeing 27v as a fault and below LVC so one needs to manually raise the cell voltages to 31/32v at least, then the BMS...

One can't legislate for stupid /thicko's.

As can be seen in my thread below, matching rims/wheel builds are compulsary with hues of Blue being the in thing. Learn to build your own wheels then you can use any rim you like. Roadrat Alfine 8 with G370 hub build. | Pedelecs - Electric Bike Community

I cover the the battery cells I'm not working on with thick card and old cereal packet is idela for cutting up to use for temporary insulation cover for the exposed areas. The power feed off takes need consideration and thinking about for best equal power flow, don't take it for granted to...

There are some like that in my town but pedestrians are too stupid and thick to understand the separation so walk where they want. Some in my town with the split paths have a raised 3" upper side for pedestrians and the lower side forms a kerb for bikes so they don't stray in to pedestrians path...

Your battery cost will likely be no cheaper then buying , one will need a good mini spot welder to carry out the welding of interconnectors . A good spot welder and powerful batteyr source to provide the high amps for the process will cost approx. £200 +, one can buy very cheap all in one spot...

Why ? Unless you have a special need to use certain cell types/brand or need a batteyr to for design reasons then it is far cheaper to buy a battery.

Well then if that translates as stated then #10 nails it. 36v is to low after powering on and will mean the battery is weak /knackered or out of balance if charged up.

Like we can read that , I think not .

Sag at high power /current demand will always be seen , if the battery doesnt't cut out under load then it is ok. Obviously the lower down the voltage one goes then cut outs are to be expected , if under 36v and the battery sags and doesn't cut out then one has to be happy with that as 36v is...

Any time you plan on going for along ride , 36.2v is approx. 38/40%. If riding locally I wouldn't bother charging unless the battery is below 39v.

If one is having issues then the obvious PAS setting is PAS 4 50% power/current or go the whole hog and PAS 5 100% power/current , though range will be reduced some what. Effienecy is simple PAS1 and ride above the cut off speed as much as possible , however if one has issues pedalling getting...

The original c961 showed watts output.

Personally I would avoid a mid drive bike unless it has a throttle. Wisper are totally legal bikes with dvla approved throttle options if one goes with that package, Wisper will will have the bike tested and approved at a MOT center. Once done it is a one off test and one gets the paper work...

Your spokes will be 2.2mm /13g and coated steel or SS.

Differerence between fast charging a Tesla and a EAPC batteyr is night and day, the forma having 1000's of more amps to with stand any faster charge current .

Cheap China EAPC's will do the job they are built for which is to get people around, they are functional . The best and first upgrade any one can do is simply replace the no name crappy speed control controller and display with a KT upgrade for about £80, the next best upgrade is to replace...

The programming software can be down loaded from the internet or have a look on Endless sphere for it for free. The lead costs about £20 on ebay. Guerney is your man nowadays who is in to the BBS01 , I gave up on it years ago.
