Re: Signalab bms, need more amps.

I think ping told me to put solder on the shunts to raise the amp output. Ping also has a 60amp.BMS it's a lot bigger in size. Before you put solder on it let someone else back these up.

HVC for ping 48v 2a charger ?

My ping 48v 2a charger hits 61.3v Is this a little higher then it needs to be ? Or If it charged at 58v will it still balance through the bms if all led (2.5) lights go on with the cells being 3.6v ? Can the charger be turned down ? Would this be easier on the life of my battery ? Should I wait till...

Crash, Have you tried to use a single cell chargher to bring up the low cell to help the main chargher with the balance of the cells. Yes you should give it some time before the long hauls are you still running a 40amp. controller at 40amp. ? My battery is starting to balance to 3.60v even the runt ...

Crash you need to flux and heat the piece then add the solder to to the heated piece. Good luck. And a big solder iron. Over 100 watts.

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.

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.

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 ?
