Re: Ping Battery BMS LVC Level ?

I charghed the pack it reads 61.3v hot off the chargher. After all the led are blinking, with the C.A. on it bleeds the top charge off faster.( ? ). O.k. the cells are all 3.61v but pos.cell #16 at 3.78v the same that was at 2.7v last night with all the rest were at 3.2v. After bms cutoff at 51.4v. ...

Re: Ping Battery BMS LVC Level ?

Yea Dogman,I got a new C.A. so I did a distance test. I had the bms cutoff at 51.4v all cells were 3.2v but one 2.7v you said it would be one low cell.#16 the pos. end one on the split pack. I might had a small problem when I replaced that cell. But that might be my weak link. I'm only getting 14.5a...

Re: Planning a Commuter build

I would save the alumiun bike and buy a used steal frame 7 speed front sup. rear drive motor. If you need to mod. the frame for a 48t front you can mod. a steel bike with a hammer. Plus they have good comp. 70-120.00usd. total and a seat gel up enough for a wife. I like 48v but two 36v sounds like m...

Re: Ping 48V15Ah WTF

Garyhgaryh, I thought you had a 48v batt. Then you check the 8 wires going into the bms for balance between the cells. This will help determin the state of chargh. But when you put a load on it , then it will show it true colors. I use 4mm. gold plated bullets connections for my battery. I found the...

Re: Help with BMS

That's my point about the sense wires. I had a bad one in 16 pin to the bms and have a split pack with a ping 8 pin white connector. Junk the pins moved and had to be glued after good contact. And my BMC 600 had a white three wire bullet connector pure JUNK! Please fix these simply problems. The bad...

Re: Ping 48V15Ah WTF

I also like Dogman's use of the plastic lid, I was told the biggest problem with pouch cells is dropping then, they don't bounce. Hey Garyhgaryh I don't remenber hearing you checking the cell voltage at those 16 wires going into the bms at 3.6v or above ?

Re: Ping 48V15Ah WTF

Thanks Guys, I gald I throw that out there. When I take my ping off the chargher it rides 3.80v I let the bms eat down the cells and they end up 3.60v and one 3.59v. So I was understanding that this was a balancing act. I forgot where I read it ? We do want the level to be 3.60v ? And the bms is shu...

Re: Ping 48V15Ah WTF

Garyhgaryh, After all the lights have been on for a 1hr.or more unplug the chargher and let the bms balance the pack. The lights will start blinking, a good thing. After all the lights are blinking. This is the time when all is balance. And there is peace in the middle east. It might that a few ligh...

The rest read 3.8v fix the pin, fixed the problem. All are 3.8v. The other time the pins inside the 8 pin connector had to be push in then hot glu...

Re: Ping Battery BMS LVC Level ?

O.K. it was the 8 pin connection. It was hard to detect having a good conection most of the time. This might be the reason why the split pack has problems . The 8 pin connector can have ghost relationships with half of the bms making true balance hard. I would ask ping for a new 8 pin with the tails...

One pack has a 8 pin connector to connect to the bms board the pins inside were shorten out at times it was going 1.2v to 6.3v but most of the time it read 3.6v like a ghost only at times.
