Hvae surron for a while, like this bike. I saw there are not many riding review about the bike from dirtbike rider perspective. Want to add some spice to the pile. About me I just started to ride enduro dirtbike 1.5 years ago. My skill is only at beginner's level. I was amazed by how physical demand...

Did someone do something about the chain noisy? I realized the chain is touching the bolts on the front spocket. Need A smaller head bolt? Or a bigger front spocket?

Very interested in the road registerable version. Subbed.

How will it different from the oset24?


Say if I want to buy a e-trial , future Sur Ron or oset ?
Any idea?

Can this bike be used as trial bike? How s the power delivery? Does it come with sinwave controller?

A common problem with DIY packs is not putting insulators under the nickel where it crosses the edge of the positive ends of cells. Without those, pressing on the nickel strips with your probes could cause them to touch damaged areas of shrinkwrap and then the actual cell itself, shorting across te...

It s 15s4p. Planned to build two of them and parrallel connect to 8p.

I uses vtc6. not sure if genuine but looks like genuine - with quality packing for each cell. not cheap for the two packs

i have put It on the bike for some rides. initially It is ok. But the range is not as far as iexpected. Since my Charger is 13s, i am not sure that causes the short mile rang or Its due to the damaged cells there. I will try and see what will happen.

Yeah, the battery pack worked good to me after the initial drain from that post. Looks like i need to rebuild the battery with insulator and new bms. I need to do It anyway because 1)i need to fit in a different shape of bag - rectangle one. 2) the current bms has separated charge/discharge port wit...

I finish riding from work. The juice was almost out. I took It out to meter each cell to see is any one had problem because i realize there had been a sudden power lost during the ride. I put It on the table, taking multimeter to test the first group cells. I realised the first group that connects t...

Sorry about not mentioning i did manual charge all to 3.4, before reconnect. I Let It sit for a while at from 48.7v to 46.2v in two days. Then Charged it. It is now at 54.4v,because i am yet to buy a 14s Charger. That s 13s i used Should i worry about the volt drop in the two days? or It s normal ra...

i reconnect the wire correctly now. It seems fine. i Got right volt from discharge end and the bms is not hot at all This time. I thought there would be fire for a moment.

i ll watch It for a while.

Oh! i Did Connect two of the balance wire the other way around. It has drain two of the groups to 2.2. Luck i disconnect the balance plug to the bms while waiting for the reply here.

Thanks for the reminder there

i am having similar issue on my similar build. The bms is quite hot. seems draining batteries to heat for some reason. i check the connection and all correct. currently unplug bms and found some serie group were drain but others stays same.

Have you found the cause of the issue?

Hi I am building a 14s battery pack with BSM bought here https://www.aliexpress.com/item/High-quality-14S-18650-lithium-battery-BMS-for-electric-bike-lithium-battery-with-20A-continuous-discharge/2030986292.html?spm=a2g0s.9042311.0.0.YcU2Cy. After I connected all of the balance wires, the bms start ...
