@JTAG where did you buy your fuses? All the places I found had a MOC of 500… One extra may be good to have, but 499 seems like overkill :slight_smile:

I order so much by them I must be shareholder by now xD.

Isnt 32v the wrong model? I thought 58v was the right one.

I was looking for the 58V rated one, which seems much harder to find. Do you think it’s OK to use the 32V rated fuse in a 10S setup?

My apologies, yes 58V is preferred ofc, however since we are dealing wit mainly capacities loads arcing wont be such a big deal (I mix 58V and 32V fused on different builds, but on the other hand, I never had a blown fuse xD).

Mouser does have quite a few in stock where you can order single units: http://nl.mouser.com/Search/Refine.aspx?Keyword=bf1+58v

Digikey also has them in stock and you can order 1. https://www.digikey.ca/product-detail/en/littelfuse-inc/142.5631.6102/F6794-ND/2515912

Hello everyone, So nothing’s special going on here? I’m just curious how the BMSs are getting on, maybe we can give a bit help if needed?

What is the currently calculated Price for one or two BMS?

Hi Steve, actually everything is proceeding: I am gathering components from basically everywhere and once I’ve got everything they will fly express to China. 10 components are slowing everything down because of availability. Cables are done and seem pretty well made.

Pcbs and pcb assembly are already paid.

A realistic timeframe is 2 weeks after all the components are in stock.

YAY! I can’t wait to start testing these.

Look forward to hearing how this goes - wish i’d pulled the trigger earlier to join the first group. If successful let us know how to get in on group 2!?

The connectors, cables look nice. All components are ordered, and you are waiting for some of them to get on stock? Just asking because maybe someone of us has a solution for missing parts :blush:

Pretty sure @JTAG has been making a few tweaks to the firmware too. Looks like we won’t have to upload a new firmware just to change config params :+1:.

I will pm you the list of components on backorder this evening. I dont want to overload this thread with boring info.

i was going to say 80 but ok. What’s the BMS protection shut off set at again? or is that adjustable?

@fedestanco any news? how’s the component sourcing going?

He is waiting for Jtag to make some small changes. Jtag is going to put a heat protection on the pcb

Just need to check. I assume the heat protection on the pcb will not change the overall dimension of 60mm by 140mm?

Hopefully we get our BMSes before 2020.
