Re: 36 V pack not charging

So we are looking for the group to hold voltage and capacity and its ability to deliver voltage with capacity. And not self discharge or leakage.

Re: DIY Balance Charging cells in a 14S battery pack without a BMS

No go buy a 48v charger. Don't rely on the BMS hvc and bleed circuit to control charge voltage. Not today but tomorrow you will over charge your 48v pack. I don't use a BMS but my pack be is 20ah I would need a 15ah pack or bigger and have worn out four sets of sense wires just with my cellog checki...

Re: 36 V pack not charging

Not the safest to be charging a more then dead battery cell. Remember 2.5v is zero in battery talk. Yes zero is 2.5v less then that is dangerous to recharge. When charging a battery cell or group up parallel cells. With a phone 5v phone is fine if you stop it at 4.2v and not above. It will charge to...

Re: help motor run reverse

First do JohnCR trick of swapping any two wires as I read he can do it in 6 tries ? It took me 36 and a piece of paper and and only one worked ? After the 22nd I kept going just to know. A bmc 600 geared a very fickle motor. Don't worry you will find it. Good luck.

Re: Rebuilding scooter battery

Depending on the space at hand you may be able to use automotive batteries high grade and a BMS charge them let the BMS balance them. Or buy a ready made pack with BMS and charger.

Re: BMS's C-, B- which port to connect and why ?

The higher quality cells and use them under rated specs lower your huc and lvc cutoff going up ah and putting on extra weight and size for longevity of self monitor always. Or no bms and your the man. Not a loner bike.

After 1/2 down take a voltage read on the packs and see what you get. If even use to 2/3 and get a reading is one stronger than the other ?
