dna 250 low usb current

[vapourFrank]

Hi guys, I am trying to setup my fresh dna 250 3s 1850 maxamp lipo 100c

my problem is i cant seem to get the board to charge at full amperage.
battery settings,- lithiumpolymer-3cell-1850-20.5wh

using 1amp usb supply i only get .2amps charge
tried multiple boxes and cords.

brand new lipo has perfect matching voltages, equal discharge rate.

any ideas? thanks in advance

Factors that will reduce the charge rate are board temp (you can show that on the charge screen) and poor cable with too much voltage drop.  The current can also be limited in device manager and it is worth checking that is not the case.

I tried multiple cables and boxes..all cables no change..Difference between 1amp and 2amp is only .1amp current difference between the two.. Also tried setting amp current to 2.0amps, no change. I even tried setting the current limit to .1 with no effect ( still charges at .2 amps) I restored to default settings and reinput battery values and now I have 0amps.. no current

Which version of fw are you running?

Im not sure i am away from the shop atm. and new to escribe.
but i just downloaded the latest version Escribe from evolv.
I assume it is the most up to date fw.
any possible answers appreciated!

It will show the version in the bottom left corner of device manager, the latest is V1.2SP4 link in my footer.

installed 1.2sp4
unfortunately there is no change is there a setting somewhere i am missing?
I know about setting the limit in device manager-diagnostis-set current. ( has no effect. tried multiple cords aswell, not much difference..slight -+

starting to think i have pootched board

It does look like that.

Hi,

I’ve got the same problem on my DNA. So, I plugged my DNA on a laboratory power supply with a fixed voltage and current. (voltage = 5v, current = 2A). Guess what? Same problem, my DNA only consume 0.31 A (Confirmed by the PSU)! So I've tested with all my usb cable. The result: my Triade 250 consumes 1.98 A (confirmed by PSU), only with the little tiny usb cable suppled with it !

 

So, my advise is to use the little cable with a tablet charger (often supply a current of 2.1 A). I hop this helps you.

 

Sorry for my english (it’s note my native language).
