I thought you have 28 cells in total for your battery pack( 14 series 2 parallel), am I right about this?

Off the top of my head, there’s at least two builds going on using 14 modules if you want to look them up for reference. BBBHC and Jkerle.

Just to be clear, each module has 4 cells (2S2P) so the total for 7 modules is actually 28 individual pouch cells.

However, since the cells are connected in parallel inside the module and you can only "tap" them in the middle of the series connection, a BMS can only manage the equivalent of 2 cells per module for a total of 14 cells in 7 modules.

If the company is trying to make sure you have the proper voltage and AH capacity, I would tell them you have 14 cells of 60AH each in series.

Also keep in mind, if they ask for the charger set voltage, You are getting the wrong charger setup.

If the charger is configured for CAN bus Control, there is no pre-set charging voltage since that is controlled by CAN commands.

Thank you

If you are planing to use 110v (or 120v) power service, and not 220v (240v), then tell them to configure the input power to 110v and 800w maximum. If you don't you will get an error message of "Input Voltage Error"

This does not affect performance or function, only an annoyance.

If they ask about CAN prtocol, just tell them to use the standard TC Charger protocol, it will work with the Zeva BMS.

Do NOT get "Enable" configured. Get CAN configured.

Added some battery tray lighting today on a hinge switch so with the seat closed, lights are off. Seat open, lights are on. Also got around to mounting a Kolpin gun holder I've had for around a year.

A little Garnet and Gold would have been nice....

Looks GREAT!!

Kolpin gun holder is nice. But again......with the BLUE!!

Just kidding you. Nothing wrong with supporting the "local" team!!

I see you have your monitor mounted in the battery compartment. Is that going to be your permanent spot or is that temporary?

Ha ha! I hear ya! If garnet and gold is what your heart is after then I suggest you step out to your own garage. If you're looking in mine, tarheel blue all the way!

Thanks for the kind words fellas!

Well, I planned on it being there permanently and using a Drok digital monitor I mounted on the dash. But, one of the fine members here is sending me a mount for my steering column. So that's where I plan on relocating it next week when it gets here.

Nice!!!
