This thread is to discuss usage of the Honda Fit LTO Lithium block OEM BMS boards.
The LTO 12 cell blocks each have a 12 cells BMS with unique CAN ID.
Others have done some research on these and that info will shortly be added to this thread.
Using that info I have connected an LTO BMS to the BCM Replacer and am now able to read the cell voltages via the CAN bus.
We probably won't be able to enable the LTO balancing function, however this is a very useful addition to our armoury for people wanting to use the LTO packs.
It makes the purchase of an Orion2 less critical if you are prepared to do manual balancing when the cell voltage deviation indicates attention is reqd.
That may be a very infrequent occurrence as anecdotally the LTO blocks have been reported to stay well in balance.
As far as the BCM Replacer is concerned, you do not need a B board or tap modules if you don't want them.
The BCM Replacer will run with just an A board to communicate with the LTO stuff.
This halves the cost of the BCM Replacer system to around $400...
Note. One of the taps on the display is shown as 2.7v this is correct as the led in the BCM Fooler matrix causes this effect.
The other 11 taps are all around 8-900mv..
