BMV 700 Battery Shunt monitor to have a good reading of my battery life

[edben05]

Hello everyone,

I'm curious if anyone has tried using a battery monitoring system like the BMV 700 from Victron Energy to get a live, accurate reading of the remaining battery on an e-bike. This would be closer to what you see in an EV car in terms of monitoring, providing a live percentage display.

I find that all e-bike screens, including the Cycle Analyst, are inaccurate since they only check the voltage, which fluctuates a lot when drawing power. I need something precise for my long-range trips so I can predict where and when to stop.

It's easy to do (it's a DIY e-bike, by the way), but at $150 a piece (and I have four e-bikes, so $600 in total), I wanted to see if anyone could share their experience with this.

Thanks for your input!

Making bms's VESC compatible

Ok, so I said to myself; "Self, what the heck, you've been slacking way too much, it's time to actually contribute something of value" That, and this post kinda gave me a kick in the mental rear. There are a few native vesc based bms's out there in the wild: Trampa ENNOID Chineese ENNOID...

Should give you an accurate read once setup and calibrated, Victron makes some nice, but spendy gear.

Ok great thanks I know they are expensive I was just wondering if the price is worth it for a plug and play solution that's reliable
