Discharging Lipo batteries
« on: October 26, 2020, 11:46:29 am »

Hi guys, what gizmos do you use to discharge your batteries to the safe storage voltage.
At the moment I am using a 21 watt car bulb plugged into the batteries with the low
volts buzzer set at 3.8v
Is there a better SAFE way that you use?

Yes, the better way is to use an intelligent battery charger that will control the discharge (or charge) until the storage voltage is reached, like this one.  Works like a charm.

Hi guys, I am new to Lipo,s seen some horrific video,s on u tube so I needed a charger/ dischargers that
would discharge to the storage level because I may not use the charged battery on sailing day and store it
fully charged for a few weeks.Then I started discharging them using a car bulb with a warning buzzer
Connected to the balance lead the buzzer set to 3.8v it gets the bulb very hot as you can imagine
I do not use higher voltage than 3s and 2s my lowest.
Any tip,s on storage will be gratefully accepted
