Cell Log 8 Breakout modules

Post by rwaudio » Feb 13 2018 3:20pm

I've produced another batch of Cell Log 8 Breakout Modules, using exactly the same design as the first batch.

Board dimensions are 3.4" x 7.62" (the RJ45 connector sticks out slightly past the board making a total dimension of ~7.875).

The boards are fully assembled including all connectors and relays. The Cell Log 8's are not included. The alarm connector (pigtail) that comes with the Cell Log 8 is required for alarm use and plugs into the connectors on the bottom of the PCB. (if desired the alarm wires could be soldered to the connector pads on the top of the PCB).

The Cell Log 8's require some extra securing method to ensure they stay in place during use, IE double sided tape, "velcro" etc.

There are multiple methods of interfacing with the Cell Log alarms and some of them are described further on my blog:
http://electricporsche.rwaudio.com/2...eakout-module/

I will have a wiring diagram shortly for the RJ45 connector, but it is also described on the blog and is very simple to wire up.

If you can find one or have one, the head end board from MiniBMS works perfectly with the NC loop used here.

This leads to the pricing:

1-4 boards $90.00 US each
5-9 boards $85.00 US each
10+ boards $80.00 US each

Shipping is free within Canada and to the lower 48 in the USA. For other locations please inquire.

I have 10 boards assembled and a total of 60 on hand.

There is a seller on Amazon that has Cell Log 8's in stock. (I have no ties to them and have not ordered from them so don't consider this any kind of endorsement).

I've got some of these boards (great boards, btw) and need to replace the Celllogs. Does anyone know of a reasonably-priced source? Or other monitor that fits the form factor?
Thx

The link works for me, can anyone else comment on if the link works for them or not?

Thanks!!

FYI, the BVM-8S fits nicely if removed from the case. I'm currently testing alarm functionality etc.

RWaudio, I have received the boards via ebay, they look and work great.
I am using those cheap nasty 8s alarm boards at the moment until I can secure a source for a good alternative.
The 8S alarm boards are wired backwards, It would be helpful to have the schematic for these boards to reduce the guesswork with respect to the power on relays. Can you provide a schematic.
Thanks all the best, CEDARN

Did the alarm functionality still work? I'm thinking of using these for an auto cut-out on my 72v lipo system
