Renogy battery meter not changing when charging
So I put the second full charge on my battery pack and while doing so the AH and battery % on the renogy meter never went up. When I let off the gas I see the regen kick in the little arrows going up but when charging it doesn't pick it up for some reason. Is there some trick to getting this to pick up the charger. The voltage reading on the pack now sits at 53.3 so they are charged just didn't think I'd have to reset the meter each time after a charge to put it back to full.

Re: Renogy battery meter not changing when charging
Ok again, B- goes to the pack negative terminal only. Nothing should connect to B- except for the battery.
Everything should connect to P- the charger, accessories, the cart. All P- It’s possible you installed the shunt backwards as well |

Re: Renogy battery meter not changing when charging
The batteries are all connected through the bus bar and that main lead off the bus bar is where I have the B- of the shunt. I think I need to just move the charger negative to the P- side and then all should be well. Thanks for the help!

No. Nothing should connect to B- except for the pack negative terminal. That’s it. Nothing else. Nada.
Everything except that negative terminal should connect to P- |

I moved the charger wire to P- and it started working as intended. Thanks again for your help.
