Hi, what is the best affordable power supply i can get for this charger? i heard its getting more precise, and have less spikes during charging with better PSU.
I’m a battery addict/snob lol so i dont want my charger to harm my cells in ANY way, please recommend me some unit, thanks.
+1. Good idea for a thread, I would like to know this too.
It’s already been said in the group buy thread that an old XBOX supply would work.
Most brick PSUs at around 10 amps. I think 12v, but check on that as Im not sure what voltage they are. You dont need the xbox PSU, its overkill big time, but will work fine if modded.
There are some tips on which one have been tried in that thread.
Оh thats great!!
Should i just buy used one? i need EU plug 
I couldn’t find a single one in my miscellaneous pile of about 10 chargers. All were 1-4 amps.
Sorry if this is a dumb question, but do I understand correctly that you can use a supply that puts out more than 3 A and it will not damage the charger?
i was considering something like this…. http://www.fasttech.com/products/1525/10002781/1380307-36w-replacement-power-supply-ac-adapter-w-eu-plug-
but they have 4A as well I see, so maybe I can get the 4A instead?
Thanks
More amps does usual not damage equipment, but more volt will damage equipment.
The idea behind using a larger power supply on the BT-C3100 is to get correct mAh readout when charging (Discharging is always correct).
I believe an 8amp will be fine too.
The supplied unit is something close to that IIRC. If youre going to upgrade PSU, Id be looking for 8 or so.
Thanks HKJ,
I see they have a 5A as well, I will get that one then.

My supplied eu power supply was 3A…
Hmm I faintly recall the correct amps being about 10?
I tried one like that, one that was rated at 5A. It did not solve the problem.
Using it in the car with a 12V output car adapter did fix the problem. However not just any 12V car adapter, one that is able to handle a lot of amps. The first one I tried blew the fuse internally. When I upped the rating on the fuse it melted.

I use a dell server power supply, 100A at 13.8v,
Posted pics and links here
Here is a pic of my dell server power supply
Here are the instructions on how to convert different server power supplies for hobby use, it’s a very long thread! this is where I got the idea to make one.
Enjoy!
You really shouldn’t be worrying about the charging data being inaccurate as charging data will never be a proper judge of capacity. The discharge capacity is accurate with the stock psu and that is what matters…
I’m more worried about voltage/current spikes, and battery condition/damage then the accuracy.
Sooooo…. does the power supply need to be 12V, 13.8V or 10V?
12V & 10A i guess 
I guess the amps doesn’t really matter, as long as we get the voltage correct as HKJ has stated, right?
