Bubba, I have the duo and 2 pl8's (slaved). The duo has a gorgeous display but no computer interface, and for many of us is not at all intuitive. Also, if 1 pl8 fails you have the other but if the duo fails....

I think Junsi has moved into a new class with this one but it is just a little short.

I don't see how one 4010DUO = 2 PL8's.

Is there really no computer interface? The specs say it has a USB interface.

That is for firmware updates and logging, not programming.

Price pr. Watt it's actually a cheap charger, for someone flying a 700 electric it's very hard to beat this charger as farevas price goes

Regardless of price, like a fine automobile, it has some specifications which are unique: if you enjoy using this type of equipment, price is immaterial.

The display of the 4010Duo is a huge plus for me over 2 line display chargers. Also, I'm a car guy with limited pit space sometimes so I always like a duo charger over two separate chargers.

Personally I did not find the 4010Duo that unintuitive. Spent a few minutes pushing the buttons until I figure out what did what. Never have even cracked open the manual to figure out how to use the charger.

Press knob then scroll to Save
Press again then scrioll to Exit.

May have missed a step but that should help I hope. I warned in the other thread that it is not the most user friendly charger I havee used. It is much better than in the erly beta days but will get under your skin at times.

See the last paragraph. I agree.

When you couple packs or cells in parallel you equalize the voltage over them, - so for at short period if pack voltage differs when you connect them in parallel then the pack with highest voltage charges the other pack(s) very quickly.

Thanks for that, that's what I thought would happen, I'm still having issues with understanding this 10% end current though, can't find reference to what it does anywhere? Anyone ......

I think it has something to do with how far it charges over the target so the resting voltage is affected by it.

Say you are charging at 10A then with the End set for 10% of CC when the charge rate drops to 1A in the CV stage the charge ends.

Since the PL keeps getting mentioned the 10% or 1/10 is the End charge rate used by the P{L8 and 6 when set to Faster charge and 5% or 1/20 is used for Accurate charge.

The ending charge rate yas an effect on how full the cells are at the end of charge.

Easy to follow example: Fill you auto gas tank at a high rate and after pump cuts off you can add more if you do it slowly.

4010DUO comes with 1 LiPoly Preset and PLs come with a bunch. PLs have 23 or 24 preset as delivered and all are backedup in the Libary plus some extras and it is possible to have 25 user presets all of which can be saved to commputer's HD and loaded whenever all or 1,2, or any number.

DUO can have 64 Presets but only 6 or 7 from factory and only one for each chemistry,Nicad,NiMH.Pb, LiPoly,Lion etc. At present no way to merge Factory and custom presets on the DUO. CCS makes creating and modifying PL Preset supper simple and even without the CCS PL is easier to create or modify Presets than the DUO is.

DUO has onbaord and Micro DS logging whereas PLs do not. Everyone wants them compared but they are not really all that similiar IMO.
