*** shipping cost for a single board in a bubble envelope updated below.
I designed this board for my personal use in my Porsche 944 conversion, but I had extra boards made so I am making them available to others. This is a 32 cell Lithium Battery MONITORING System, everything is isolated so any number of boards can be used to monitor most cell counts (there are some cell count combinations that won't allow all of the alarm relays to function properly, basically a minimum of 4 cells need to be connected to the "top" Cell Log 8 for the alarm output to function, all other Cell Logs should have all 8 cells connected)
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:
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.
I have also checked with Dimitri of Clean Power Auto LLC and he is okay with selling his Head End Board individually (from his MiniBMS system). His head end board will work exactly the same connected to the NC loop on the Cell Log 8 Breakout Module as it would with his regular MiniBMS system.
I didn't design this board to get into the "BMS" market, I designed it because I needed one (3-4 actually) it was a small PCB run of a fairly large board so the cost per board was a bit high, there are also 17 three pin connectors, 4 slim spring connectors, an RJ45 connector and 6 high quality hermetically sealed relays along with the 4 connectors that the cell logs plug into along with my time to assemble the board and the time to design/layout/order/test this PCB. This leads to the pricing:
1-4 boards $80.00 US each
5-9 boards $75.00 US each
10+ boards $70.00 US each
(I am located in Calgary Canada)
As of today I have 50 raw pcb's on hand and parts to assemble 17 complete boards, the first 17 will be sold on a first come first serve basis, I will then order the parts to populate the remaining PCB's.
***Shipping cost for a single board in a bubble envelope within Canada is $3, to the lower 48 States $4
Shipping for any number of boards is $20.00US to the lower 48 US states
Shipping in Canada varies quite a bit so for the best rate send me your postal code ($15-22 for the variety of the postal codes I tried)
I will ship virtually worldwide just give me your address and I will get a quote.
