I'm using the Lithiumate Pro, vintage about 2010. Once the firmware was updated
the system works very well. There are small PCBs which monitor each cell
voltage and temperature. The cell boards are mounted directly to one of the
cell terminals, giving good temperature monitoring contact. Each cell board
also has a top balancing bypass resistor which is switched in and out of
circuit as the master determines it is necessary. High power balancing
resistors are also available if you need to bypass more current than the cell
board can handle. My 100 CALB cells are grouped in 10 banks of 10. This
requires 10 four conductor cables from the master, making interconnect wiring
reasonably clean. The cell boards connect in a series string with a single
conductor. The tricky part is to get the single wire routed to minimize loop
area to prevent noise issues. The master has both analog and digital as well as
CAN interfaces, giving you many ways to interface to the charger and controller
er. It has CAN protocol messaging already installed for many of the popular
chargers and inverters. There is a file of PIDs available as well so that you
can set up Torque or similar OBDII display apps on tablets and cell phones to
monitor the pack with a bluetooth dongle plugged into the car interface
connector, instead of using a PC with a serial interface.

Subject: [EVDL] BMS recommendation/ experiences?
Content-Type: text/plain; charset="utf-8"
Hello, I've been driving my Dakota truck EV conversion for over 7 years,
and finally pulled the plug & bought a lithium battery pack. (46 CALB
cells, which should arrive this week!). Now I'm looking at BMS's, and am
curious if anyone has any experience with the Thunderstruck BMS? (
http://www.thunderstruck-ev.com/bms/ ). Positive/ negative experiences from
anyone who's used it would be appreciated; I'm also considering Lithiumate
or Orion, but those seem quite a bit pricier. Thanks!
