    Advice on ebike conversion kit for 30mile commute

    Regarding my post a short while ago on reduced capacity of my bbshd52v 30Q battery.ie 58.8v permanently down to 57.5v. Do you think this is why after 1500 miles in a year that happened? Not just because it never got balanced.due to me not knowing it had to be switched on when charging. But...

    Bafang 250W amazing range

    anywhere here in cornwall basically...lol. ill take a look but ive realised by now most e bikers use lower PAS than me.

    Bafang 250W amazing range

    yes i added the 2nd battery so i cld use max assist most of the time,hence slightly worse. An definately full on uphill.i guess i feel low assist i might as well ride a regular bike.but my slightly arthritic 50 year old knees love it. id never get up a hill in PAS1-2 theyd ignite.

    Bafang 250W amazing range

    good tip,ive found more recently riding both the bbs01 & bbshd feel much better leaving on the 17t-20t cogs all the time.both have 42t narrow/wide chainrings.

    Bafang 250W amazing range

    incredible i just dont know how all you guys on here get these ranges. My bbs01 18amp on a giant sedona only ever gave 27miles on a 17.4ah battery. Derestricted and mainly used on 4 of 5 levels PAS.last few miles crawling back on PAS1-2. Now it has 2 batteries totaling 30ah i still only get 40...

    Advice on ebike conversion kit for 30mile commute

    then buy a bbshd with a 52v triangle battery of around 25ah + and you can have that 30mph speed all the way,ideal.the torqe the bbshd produces for hill climbing and acceleration is amazing.in hindsight i would never bother with anything else....if i could afford a large capacity battery.my 350w...

    Advice on ebike conversion kit for 30mile commute

    60miles range at 30mph is impossible. my bbshd (mtb, chunky tyres)will easily maintain 30+ mph on flat terrain. but the range from my 15ah 52v 30Q cells, maintaining that speed wld be maybe 16 miles max. cutting power to average 20 mph , can get 27 miles range.the biggest batteries ive seen are...

    Battery capacity running down

    its normal for the controller to constantly vary the power due to things like accelerating.lowering the power when up to speed and the degree of incline/decline of the terrain an choice of gears, the amount of power needed will continually fluctuate. the higher the assist level the watts wont...

    Battery capacity running down

    ive had batteries lose range because they have become un balanced,as vrf has said. does the battery have a dumb or intelligent BMS? if intelligent ,does the battery have an on/off switch? it MUST be ON when charging for the battery to enter balancing mode. You can read all the cumulative cell...

    further investigation of battery cutting out before set LVC

    Seems all good.today blasted around using plenty of mid 20s amp draws,rough offroad, hills,stretches of road at 30mph. Covered 19miles with still 46volts at rest at the end. last few hundred yards was giving it blasts of WOT 30amps.didnt cut out at all despite the display showing voltage dipping...

    further investigation of battery cutting out before set LVC

    Hope so,going to give it a mix with plenty of full power today see if it can still gives 20miles. i rechecked electroncycles battery charging instruction on their site and the leaflet with the battery.neither mention the batt must be ON to achieve balancing.my batt never got a proper first use...

    karls special sauce setting on bbshd 30amp controller (5 levels PAS)neal. trying keep current at 55% & current decay 1 at the mo. on the subject of KC & current decay. the settings dont seem to function as id imagine. on say 70% KC, EXCEPT PAS1,theres no reduction whatsoever of amps,even on the...

    further investigation of battery cutting out before set LVC

    today rode 26miles on PAS1&2.was pulling 10-12amps on the last mile to home ,uphill all the way.voltage hovering around 44v without cutting out 45v at rest. Started out at 57.5v. when the battery was newer id get 27miles with similar power use. reckon it wld have gone down to the 42v LVC. Next...

    further investigation of battery cutting out before set LVC

    Hi neal.i didnt ride far enough today for a full test.However i was pleased to see i used only 6.3v of the 57.5v full charge to do 14.2 miles. that inc plenty of hills,pas2 mainly approx 18amps.with fair bit of 21-24amps, WOT & bit of PAS1..a good mixture basically.voltage drop on the display...

    hi dave yeah i meant bms balancing not charger.i meant i could see the charger periodically turning on and off after green light.no never charged to less than 100% always green light plus few hrs, but i never had battery switched on during charging before.never saw the charger ever come back on...

    update. after using a mobile phone charger to equalize all the cell groups i put it on a full charge. the charger finally went into balancing mode for the first time in the year ive had the 52v battery. didnt know battery has to be switched on to enter balancing mode and it was quite out of...

    Kit recommendations

    i tried my 18amp 350w bbs01 set at 18mph but that sudden drop of assistance is unnatural the same as 15. because the assistance always allows you to keep reaching the cut off whatever it is. the only thing that feels right is totally unrestricted to the top speed your gearing allows. in my case...

    Kit recommendations

    derestricting the speed limit is pretty easy except i believe on bosch.But the faster you go ,as ive found massively drains the battery.25mph will use twice as much as 13-15mph. i think you will need a cart for a battery than can deliver 12hrs of continous assistance lol.Dont believe the...

    further investigation of battery cutting out before set LVC

    thanks sturmey.im trickle charging the cells all to the voltage of the highest one 3.50v with a 450ma mobile phone charger.then ill give it a full charge and a good balance.they should all reach 4.2v hopefully then. you are right, i did some math and worked out i was loosing the use of 5v of...
