Ping battery BMS

[psycosis]

I need to get a new one of these since my one cooked itself this week. Its going to take weeks to get one from China, does anyone know where i can get a replacement item from in europe or the US?
Its the v2.5 48v 20amp battery that i am using.

I have a spare one that i think may be broken, but i don't know how to test if it actually works. I was sent a replacment as i don't think it was balencing the cells properly.

HI psycosis, ck with Terry at http://www.hightekbikes.com/BMS.html. He is selling the same BMS that is used by PING.
Good luck.

Wow quite a bit more than Li Ping, $46 + shipping directly from him, shame it takes so long.

I recently bought one from Ping and received it in less than 1 week

Unless Ping has changed his policy, he will not sell the latest version of the BMS that he ships with his battery. If you buy from Ping you will be getting the older version of the Signalab BMS. Something to consider.

The replacement should be the new version, i had a replacement about 2 weeks ago when the first one just stopped working and didn't do anything with the cells, they all became unbalanced.
Here is a picture of the BMS, sorry about the quality it was taken with a camera phone, pretty well broken as the legs on some of the components have burnt off.
On the other side the resistors have actually become detatched and stuck to the board that was shipped.
I will see how long it takes, i placed my order last night, just have to make sure its ventilated better this time i guess.

Wow that's smoked it must have shorted out. I put mine in a seat pouch and hang it from my seat post sideways,I also unzip it and pull it out when charging and wake till the bms starts blinking. I also need to build a box out of pexiglass two sided to vent.
