Do they have a better version of this charger ?
what i would like is features like:
1) voltage display
2) how many mwh was used to charge the battery
3) meassure battery condition
4) stainless steel terminals and center post
5) spring loaded center post

I know that it is not likely to find charger that has all features, but is there any that have even some of them ?

Not a charger but SKU 1859500 fit 3 of your requirements.

Good idea!
I ordered one and will try and set it in line with with a normal charger to get an idea if batteries are half bad.
or maybe make a multibay 510 charger from SKU 1203300 by making an insert with spring-loaded 510 adaptors in the bay, and 2,5ohm resistor on positive lines ?

Not sure of what you are trying to accomplish with that.
Why would you need a 2.5 ohm resistor ?

SKU 1270407 are based on a TP4056 IC, those type of chargers require ~5 volts input i you want to charge your batteries to 4.2V.
Same as SKU 1453504.

All you need is something like SKU 1142400 + SKU 1859500 + SKU 1270407
(or SKU 1009300 + SKU 1453504, optional modified SKU 1229701 to use it as a battery holder only.)

i would get a multibay ego charger with an indicator of how much current a battery can recieve (to sort out bad ones) and i would like the ss setup so i do not get so much gunk in the battery
I'd use a resistor to limit how much current each battery receives, many of them are only 650 mah, and also to minimize 1 battery discharging to charge another. but SKU SKU 2137700 solves the problem perfectly

I see.

I am not sure if an ego battery can discharge without pressing the fire button.

Assuming your charger was to provide more mA than required, you would had needed a 9~11 ohms resistor for each battery in parallel, to limit the current to 466~380 mA to each.
A 2.5 ohms would hae allowed for up to ~1.68A @ 4.2V

Wouldn't the charger try to supply max 4.3 volts and the battery voltage be around 3.3 volts, so that a 2,5 ohms resistor would be needed to limit the current to 400mA ?

You are right.
I was forgetting the voltage difference.

Does this usb charger 1270407 quality and does this it can fill by the end of this battery 1866507 ? Does this flash red light while the battery is in the charger and does this flash green when the battery is charged?
