Lipo batteries will have a short life and puff if left at a full state of charge all the time, which is what I presume that you are requesting of a maintenance charger.

Not a good idea with that battery chemistry.

Ion packs differ than Polymer packs. Polymer pack have to be put in a storage mode, basically charged or discharged to 50%. Ion packs you can leave fully charged, and ready to go at any notice.

A123s you can leave fully charged, and top them off at the field.

Takes my Polymer packs, less than 20 mins to charge at the field. Charge while assembling the airplane. I use iCharger 406 and 308.

These types of packs arent your typical car battery or NiCad or NiMH pack, to where you can leave them on a charger for weeks on end......

This theory does not apply to Tx-Rx packs with low C discharge rates
moreover smartphones, tablets.. now come with Lipo batteries too.

Because your "dumb" phone can work off AC power, too. Im not leaving my Tx plugged into a charger for more than I need it to be. 100% of the time, I take my Tx pack out. Because I cannot fast charge thru the Tx charge port.

Good job in freaking people out now, with their polymer batteries in their phones..... They will be charging in ammo cases.

Most any of these type of batteries can hold a full charge for days or even weeks. With that said, every battery on the planet can be fully charged in 1hr or less. How much faster does a person need it?

I mean just leave the car running, so you don't have to waste time starting it, and leave the planes in the car too so you don't have to load or unload.

Best is, just live at the flying field, sleep next to the pilots station, wake up and fly.
Zero time loss with that.

what the heck are you talking about ?? do you even read your posts before posting ??
it's you who claimed that ALL Lipo batteries must be stored at 50% and I stated that this is not necessary for Rx-Tx batteries if you fly weekly...
