Endless Sphere

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.

Now charge the low parallel string to 4.1v and see if it stays don't ever go over 4.2v.. Good luck

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...

Sorry to hear about your health. Hope you get better.

I bought two of those one a una9plus and a una9plus+ with battery nanny. I just bluk charge a 24s and check the 4-6s sense wires for balance and on use the 6s opinion. It has a 6s and 3s female plug and many stlyes of balance board's. Plus battery nanny never used like 24- 3s and 8-6s in the nanny b...

A midrive works good on hills regen is only about 8 percent. And needs great torque arms. What motor and controller do you have ?

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...

Thank you JohnCR much love .My friend. I just don't have access now. Triing.

Put sold in title please .

Still a link to the scooter for good advice.

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.

Use very little throttle if doesn't work don't use more throttle try something different. Not more throttle.

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.
More info on electric scooter link pictures something

Open it up a have look see. Does it have 63v or 75 v Caps or ? If 63v it should work. Just like a motor or battery you can melt down long hiills ect.

A 17ah pack would have less stress if use the same it also how you use or abused it. Do you ride wot or ? Hills ect
.

1v ? As low I would temp is 2.8v that's empty. 3.0v is more safe charge to 4.2v let rest and see if they hold voltage

I bought use high grade makia packs that where open up and recharged and sold as 3.0 v and above 350 cells. Yes they came that way but we're just juiced up. Money does weird things to people. I can tell as he took the white plug out of most. He was looking for the newer pack with split tab welded. F...

Nice bike why not the battery in the triangle ? How fast on flat land ?

Nice bike . What battery and controller . Amp rating of controller ?

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.

The only time I worry is when I do a deep discharge. Caught to far form home or a curious test of lvc. This is the only time I'm certain. I recharge and watch. I had two problem with signalab bms:s problems one time killing one cell in 4 parallel repalced all 4 on old ping pack. Then stolen. Hillhat...

I bulk charge them check with cellog thru 4-6s
( you 4-5s) sensee wires if unbalance I use an an,9plus+ thru the sense wire charger for balance. But never needed 1,480 charge cycles. Only use 6 times. No bms

I would just use 9-10ah and see how it works out

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 ?

Makes sense as I heard a boom a Sonic boom I had the cav3 set at mach 1.
Ok found CA set at 40mph I go 43mph. I reset it but it still blinks ??? After unplugging and repluging it
