4s charger and connector questions
I was wondering what you guys are using to charge 4s batteries at a decent rate. i currently have an icharger 308 but have been thinking of down sizing. problem is finding a decent charger that can do 10-12 amps on 4s (yes i understand watts to amps calculations, just wanna know what ya'll are using). Also, i have been looking at connectors cause my deans just arent cutting it anymore in my 1/8th scale stuff. i really dont want to do EC5 and have been looking at xt60 but not sure if they are enough seeing as my deans arent enough anymore. I dont want to run the massive xt90 if i can get away with it.

Most modern chargers run even higher wattage with a properly sized dc power supply.
I have a Dynamite passport ultra p2, and a 13.8vdc 19amp power supply. Capable of charging one 4s at 13amps.
On ac this charger only does 100 watt or 50x2 or on dc 100x2

Use real Deans connectors... not the cheap copies....
I use the XT60 on my 1/10 truggy and my short course....
Had an issue last weekend in my short course, truck died halfway thru a race... turns out the male ends on the XT60 were not making good contact. I had to use a small screw driver and spread them and it corrected the problem. You would not notice this due to the plugs snapping together so you assume you have a tight connection....
New male plug installed now

i use the xt90. I see peaks over 140 while in use which doesnt make the 90 imperitive but it might in a couple years and i dont want to change again as tech develops.

You need about 200 watts of power to charge a 4s battery at 12 amps. I use xt90 connectors and a skyrc d400 charger. It has a internal power supple so I use it on ac mode and it has 400watts max power at max of 20 amps charge rate. so I can changes my 4s batteries at up to 20 amps no problem.

I use an ISDT q6 for field charging. For connectors xt60's are fine for 1/8 if we're talking racing. Amp draw should be relatively low.
