Club car ds iq and navitas 440 amp 4kw upgrade

[Michigan80]

So did a whole iq and navitas ac conversion on my 95 club car ds . It ran several times and now I am getting a 3-1 code saying “bus undervoltage fault “ voltage on batteries has dropped below 18v . I have new batteries that are fully charged and all battery bolts connections under the seat are tight . Not sure where to start looking ? Any help would be greatly appreciated! Thank you

Well fixed it !!! My advice to anyone (yeah I messed up), make sure all your connections are tight !!! I forgot to tighten the two solenoid big bolts down 🤦🏻*♂️🤦🏻*♂️🤦🏻*♂️🤦🏻*♂️ Easy fix , rookie mistake !!!!

How's the result?
I just finished a DC 600 navitas and a Eco battery.
it's insanely quick, I have to keep it at less than the std settings,
at least until i get used to the torque.

Results are way beyond expectations !! Just finished the hd springs and new rear shocks and what a difference !!! I have brand new batteries but I’m a few years when these are dead , the lithium battery will be my last major upgrade !! But would definitely recommend !! Went from slowest cart to one of the fastest !!

What kind of speed are you guys getting?

My top speed is 31mph but I've settled on keeping it at 25 with a regen setting that really helps me slow down.
The acceleration setting is where the fun is at.
