The settings could you see in the pictures!

I checked that it happened every time just on PL 2.

If I charge 3 2S on PL1 and 2 6S on PL2 it happens the same. But if I charge 3 2S on PL1 and 1 6S on PL2 it works.

In the passt I didn't have the same issues. The BUMP controller bought from Hugo Markes and it is from the first batch.
Since u said "first batch", do u know that it is one of the original units that does not have the noise filtering improvements ?
If not certain, and u have an ohmmeter, unplug everything and check resistance between power ground and PL port ground - if it is 1k ohm it has the noise mods, if it is 500 ohm, it needs to be sent to Revo for service.

If it happens again, make a note of all the conditions of the charge in order to make it easier to reproduce and test. Battery(s) being be charged, charge rate, fuel level, power source/ generator, etc.

BumpCharger.com will service it for free, shipping included, if the problem persists.
Hi Kelly,

I will do that.
Just to let you know, I used the charger case all day Saturday, Sunday and Monday without any problems. I'm guessing about 30 charge cycles over the three days using the same type batteries and accurate charge (1C) that produced the original code but it hasn't happened again.
I will be ready with all of the info if it does. Thank you again for the great setup!

Two BUMP Controllers


Is it possible to have a 2 BUMP controller set up (a fixed charging station + a mobile charging box) managing a single set of batteries?

Yes, its not a problem - the unique BumpTag ID will keep all the history straight across all controllers/chargers.

Had both issues (I posted about earlier) happen yesterday at same time using lead acid supply batt: improper low-supply cuttoff happened (at 11.4V or so even though set to 10.5). Then, did clearing the red error screen on BC improperly clear that slot? Because I apparently bumped the battery again creating an unintentional x2 parallel charge and even worse I was set on Fast charge. I happened to notice crazy charge current, otherwise I'd have been charging at 8C - not good!

(Had a thought on low supply issue: is it just that BC or DPL can't actually operate below 11.5V even tho you can set cutoff down to 10.5?)
