Yeah, but at $50 each!!!??? Bosch are much more attractive for multi setups.Sorry, I only have Dewalts to play with. No plans on using any other packs since the Dewalt have been very reliable. I will be getting the Dewalt 28volt packs, and will verify if those will work.
I'm try to use the 28V pack too, but I'm not able to activate the BMS with the 3 resistors like on the 36V pack.
I blew the fuse and shunt it by a external between the BAT- inside and the output Pin outside, ratter to dig into the pack to change the SMT fuse, does it a problem ?
Do you confirm your pack in 28V is working with the same resistor network ?
I blow the fuse before to find this forum and the board of Kfong. So don't worry Kfong made a pretty good job and you can trust his tests.webfootguy wrote:Did you blow the fuse before or after trying to use the interface board? I just got the rest of my parts to build 2 interface boards today and I have lots of 28v packs so I will give it a try fairly shortly.
webfootguy wrote:kfong, I'm about to finishing building mine and test them as well on the 28v packs. What inductor do you recommend and where should it be inserted in the circuit? I'm assuming either the + or - pack would be ideal. Does the inductor have to be rated at +25 amps? Those seem spendy. Can you suggest a part to experiment with?

Yes, I don't use your board yet, I just tried quickly with 3 resistors to be sure that my pack is still working.
What do you think, please ?
Does my fix for the fuse bad ?
Do I have to buy another pack to use your activation board ?
For remember and more detail: I shunt the fuse inside the BMS by a polyswitch resetable one of 2.5A beetween the battery - polarity and the extarnal pin 1.

The schottky diode is on backorder and it looks like they are anticipating at least a month out. Is there any way I could replace it with a V30100C-E3/4W? This appears to be almost exactly the same other than the surge amps is reduced to 160A instead of 250A. Digikey only sells these in multiple of 1000 but mouser sells them individually and the have a whole grundle of them available. Can you help me.
