going to run 8s3p cells so question is, the voltage indicators on eBay ( cheap ones ) rated between 3s to 15s only do 12v 24v 36v them 48v but my setup is 33,6v so how do I do? will it work or what?
The volt value will still be correct, only the percentage will be off by a small amount.
so if I buy one I should put it at 36v?
yeah do you know how many percent the difference will be? I assume silmillar to like 95% is 10%?
100%/x%=36/33.6 (100/x)*x=(36/33.6)x - we multiply both sides of the equation by x 100=1.0714285714286x - we divide both sides of the equation by (1.0714285714286) to get x 100/1.0714285714286=x 93.333333333333=x x=93.333333333333
now we have: 33.6 is 93.333333333333% of 36
Jesus. You could’ve just done 33.6/36 = 0.9333
E: BTDubs, thats not how those percentage meters work. Your battery capacity does not correlate linearly between 36V and 0V. There is a discharge curve between 42V and 30V for a 10S (36V) display. The percentage is mapped to voltage based on this curve. 36V is ~50% in this curve and 33.6V is ~10% so your display will almost always show 0% if you get that.
Look up LY6N or LY6W battery display. Those work for 8S too.
Yeah Jesus don’t worry… cause he came back to life this weekend
Completely forgot it was Easter…
I think most of those meters do 12,24,36 and 48 with lead acid batteries but they also do 3s to 15s lithium batteries. This one does both: http://www.ebay.com/itm/12V-24v-36V-48V-Lead-acid-Lithium-Indicator-Battery-capacity-Tester-volt-meter/172018886570?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D40130%26meid%3Dd113753123854c1a95c8a63e1d5535d4%26pid%3D100005%26rk%3D5%26rkt%3D6%26mehot%3Dpp%26sd%3D331810603701
Yeah so What do i do for A 8s setup?
He literally just pasted the instructions above…
yeah for 12,24,36 and 48V 8s is 33.6 literally…
If you’re not willing to read then I cannot help you
I have already looked at the ly6n and w and its the same, supports 8s but only 12,24,36,48v
put it in L8 mode… it’s made for 8s battery…
And What volt setting?
