Ultra Power UP100AC Plus battery charger

[WideOpen]

I bought an Ultra Power UP100AC Plus AC/DC charger. This charger also does discharge and storage.

• How long in-between runs should I do the discharge and the storage?
• And if I am putting it into storage, do I need to discharge it first and then run the storage mode or would just running the storage mode also discharge the battery to the correct amps?

I storage charge mine every time we finish running for the day. It's not good to let a battery sit too far away from 3.7v per cell or so.

And no, you don't need to discharge it. The charger will automaticslly discharge or charge the battery to storage capacity, no mattery where it's at in voltage.

discharging on ops new charger should be fun 10 watts .info says up to 5 amps my math says no way id get a spare balance board use a lipo buzzer build your own discharger..good luck(just about @ ivas then off to my favorite roadside park to eat)

poofdaddy - you just talked way-way over my head - say that so a dummy like me can understand it.

Get a proper discharger and use it. Most chargers will "discharge" a pack down to storage charge, but they don't do it quickly.

- adjustable voltage/amperage.

- has bluetooth, assume things can be adjusted like amperage and end voltage. Default is 3.8V I think.

- can be connected to a PC with another device to adjust the default "discharge to" voltage. Default is 3.8V I think.

All 3 of those bulk discharge without balancing by drainging the pack via the main plug. Then you can put it on your charger and "storage charge" it with the balance plug also plugged in to balance storage charge it, so the cells stay even.

The one decent quality discharger that will balance that I know of:

The cheap discharger I use:

It's cheap and will pull 150watts. When it gets down close to the set voltage, it doesn't use the lights, it uses a bank of internal resistors to drain it in balance mode at 5w, which is slow... I usually set it to 3.7V and when I see the lights go out, I unplug the pack, then use my charger to bump the packs back up to balanced storage voltage

I took it apart to see if I could mount the lights to the housing, then made an aluminum shield to block the lights as 150W of light is a lot of light/heat.

I later made a shield for the top/back and put a fan on it. It was winter and I was bored.

its called OHMs law wide.using your listed charger will take you hours to discharge a fully charged battery over 2500mah 50c
