I used it on an older setup to determine my peak amp draw, power in watts, etc. Cool info to know. Also helps me determine actual battery amp supply for future builds (using same motors/gears/etc.).
Mine (i think the GT 150a one) shows peak as well as some live data, but saves the peak values and rotates them to view when you stop. It however does not have memory and once powered off is reset and data is lost. Here are some old pics of mine showing amps/watts/etc.
at a stop - no amps. 30.6v left in the pack (8s). 1921 Watts peak. 1.x Watts at the stop (maybe wheel was still spinning a bit?)
Again no amps - 30.6v left (8s) - 65 Amps peak (dual 5065 200kv VESC) - 2.1 Watts at rest (not sure why).
It cycles through mAh/Ah consumed, and a few other things - the ones i wanted to see was Watts and Amps peak. Just as good info to know.
You can add sensors (temp, GPS, etc.), and a LCD display - pretty modular but a bit $$ - especially compared to a $20 watt meter like above. Select what you want to see as well on the graphs depending on sensors you have. Pretty cool really.
Another option is the Speedict Mars/Mercury which does similar (actually some really cool views - this is just a quick pic i could find of the graphing. Some great map overlays w/ info at each point - using the gps in your phone for location vs a gps module):
Sleepy Iāve never seen that speedict thing! Awesome how every cell voltage is shown in realtime on the phone! I want it badly and as long as itās not too big in the board. Just started checking it out and it looks small and at 90$ worth it. I ruin cells so quickly this is a money saver. U like it? Or it seems u havenāt used it
Just got it the other day! - plus the Mars inline as well. I now have both the Eagletree eLogger v4 and Speedict - one planned for each of my next two boards!
I can easily use the Speedict Neptune Lite (their āBMSā) on one of the boards to try it out - what do you want to see?
I remember seeing a couple folks who incorporated it into their enclosure - screen removed and set into the case/enclosure. Let me look at see if i can find a pic. My original plan before i went off the deepend with the Eagletree and Speedict.
@okp - he used one in his original vaguard build:
And the one before also i think.
Iām looking up the speedcific stuff and itās really nice
Iād rather do the visual part on the phone than try to jam anymore stuff in a board.
Man if only they integrated a simple balancing feature Iād be sold. I have all these little balancers for ten bucks and Iād still have to use them with this. A simple discharge balancer and this thing would be fantastic. Donāt know why they donāt. Anything u know that does that? Not necessarily a bms but just a simple balance feature
really Iām looking for a balancer for 12s. Something like the battery medic but that can do 12s. the other features are helpful but if they canāt discharge also itās back to the same thing. How hard would it be to make a 12 cell balancer?
Hi there! Know I that this is not the newest post - although - I was not entirely clear on the calculation. Can you do an example?
I tried to input the numbers, like 240wh (for 10Amps X 24v), then dividing this number by 2Ah, gives me 120. What exactly is this number and is there any use for it? I think thereās a point im missing here
Been looking into understading batteries better so this would help with that.
And the one before also i think.
