great idea, thanks a lot!!!

I leave my controller plugged in, but with the ignition cable disconnected. Don't know if that's what you meant.

Yes me too leave the controller plug in with the ignition cable plugged in while in charge to see the voltage on the cycle analyst but when fully charged i unplug the ignition cable ...the controller is always plug

Is this refering to all battery types or is this just LiPo?

I use timers for lead acid and charge on the bike/scooter in the garage unattended.

For my Ping LiFePo4 I plug it in inside of my house with my Turnigy watt meter so I know when it is almost full. Once it is near full I hang around till the lights on the BMS come on and I unplug it.

LiPo, which I just got in to, I always charge off the bike, outside on the concrete patio. If I walk away I put my BBQ lid on it lol. I also use an Icharger 206b with all the safety features enabled i.e temp sensor, time limit, max AH output ect.

Sorry to bump an old thread, but

I have nine 6s turnigy lipos on my bike arranged for 18s 15Ah.

I charge with the packs attached to my bike, in an unfinished part of my basement or in my garage against a wall, and I leave the controller plugged but switched off in when I'm not going to charge between rides. I do not attend my packs during charging, nor do I balance charge my lipos. I have left the house with no one home while they were charging on several occasions. I do not worry for the most part.

I check the balance of my packs about every month, once at the end of a long ride and once after charging. I have my hyperion charger set to charge unbalanced to 95% TCS capacity. This is usually about 25.02V. I very rarely discharge more than 80% of my pack. I usually only discharge to no less than 60% before I charge it back up for the next ride.

The only low voltage protection I have is a buzzer that attaches to one of my 9 packs goes off at a programmed amount. iirc it's at about 3.3V/cell. Only a few times in 1.5 years have I ever had it gone off.

I may be on the edge of disaster, but my packs have <150 partial-cycles on them and the cells are always in balance when I check. I would say my pack is in good health. If I think otherwise, I will keep a closer eye on things.

The survey has no expiration, to keep a running account of common practice.

Can generally charge in under an hour with multiple Meanwells.
