Managed about 42 miles of powered riding from the 12.5a HE2 & 15.9a Boston cells which meant 21/22 miles unassisted into the wind. On their own the Bostons are not much good and the 39a of the pack sags terribly, with the 100a HE2 pack things improve dramatically but range isn't quite enough for...

Nice ride out with #2 today, Garmin say's near as a damn 63 miles & cycle computer with correct wheel size input say's 65ish. My minor battery repairs mentioned in post #95 to the HE2 pack worked a treat this time a full discharge to cell cut off 3.1v. Might have a tinker with the front Magura...

Your current use is illegal no matter who, what, how or why. It has to meet current reg's so requires pas which mean you will need a brushed controller that has pas connection. Controllers also protect the batteries by drawing a max load, currently your motor can draw what it likes form the...

Smart ebike much a different case with a limited sales market, you may be fortunate.

I doubt it, the Smart ebike isn't made any more is it ?

HE4 & HE2 are good, I use a HE2 build on the Swizzbee and is very good as up to 60 odd amps can be the load, though only 2500mah. For a 17a controller and if your not doing man miles the PF is a great cell. I mainly build all my batteries now, still have 3 hard case batteries which I have...

The GA in price is very similar to the 30Q on Nkon so should not be much different in real term battery cost though we know battery mark up is a rip off. PF and GA are both very good 10a rated cells, GA is obviously more expensive because of the extra mah, also LG MJ1 is another very good 10a...

Makes sense if it was a 48v one mistakenly fitted but most likely is the 36v one is failing/faulty. My Oxydrive bms was a solid state Lishi controller and the fault as you are having was the same.

The shrink under the jst's is a smaller size shrink wrap for my 3s packs so I cut it and it reaches down about half way, a dab of hot melt keeps it in place until place the final wrap. Then it all get's a good wave over of my heat gun. If you want to you could place the shrink over the jst's...

Looks pretty good to me, looks like a upgraded EU copy of the Korea Boss model. It has foot controller which the Korean Boss doesn't have and has a bit more protection with the 3d enclosure & a mini fan built in to the case, all in all maybe worth the extra cost. Worth considering if anyone...

After a mile does the power cut out ? If so then the gontroller is probably faulty and controller lvc is cutting in. I had this with my old oxydrive controller, the lvc cut in though both batteries in use had plenty of V's in them. The display gets its comms via the controller so it is the...

#6. BMS discharge/P- soldered to black tail of XT60. Solder Joint smoothed out and shrunk. #7. BMS B- soldered to pack B- and shrunk. B- hot glued in place. #8. Pack V+ exposed to solder charge plug V+ wire on to. Charge V+ & BMS C- connected to DC plug. My chargers use 5.5mm x2.1mm I...

Tell us/show us how you have exactly connected the bms and wire awg used. Also I found not all contacts with the diy Vruzend were consistent so only needs one of your parallel connections to not work for the load to cause a collapse. I found that 3 or 4 cells weren't contacting properly causing...

PC are you looking at buying a battery or just cells ?

o_OMe thinks your wires are crossed or misunderstood my post !!! Samsung don't do a PF cell, PF is a Panasonic . Samsung do a 29E cell a mediocre cell. GA cell is Sanyo or Panasonic depending on which factory/country they come from, Sanyo own Panasonic. The GA cell is 3450mah 10a, PF is 2900mah...

Nice job.

Andy you are not listening !!! Any after market battery is highly unlikely to be up to the task of coping very well with your new 30a controller especially one like yours if you can buy one, the cells inside will not be all that great and will still be mediocre ones I have no doubt. Your best...

The QR axle stubs will be a bit sloppy in the drop outs though should tighten up as normal, just depends on how the wheel feels when riding and at speed.

Only 4 more wires to connect maybe tomorrow or next week. I will add pics again. Yellow BMS charge wire goes to dc charge plug negative/v-, the red supply wire prroces as described in post 1/#8 needs soldering on. Black BMS wire B- needs connecting to the uncut thick black also B-/pack -wire...

#1 & #2. 4S & 6S hot glued together with bms in place ( hot glued as well). Notice all bms wire ends insulated to prevent mistaken shorting. #3. Soldering sense wires using a helping hand, snip jst wires to required length at the same time. Cut only one battery sense wire at a time. #4...
