Much higher voltage drop than expected of an "ideal diode". When running 11V and 5A, it is dropping 0.58V across this diode. Ok for my purposes, but not ideal.

These start to burn off voltage from 2.85V, which is not healthy at all for 2.7V boost capacitors. Here's what I did to fix them for my 2.7V capacitors: (I shouldn't have to fix them, but I didn't want to wait for an active balancer) If you replace R6 with a 1.2kOhm resistor (originally 1.8kOhm), these will balance from about 2.65V, with a full 1A of discharge occurring when the capacitor reaches 2.7V. Maximum balancing current appears to be 1A, which burns off approximately 2.7W of heat between R4 + R5, both of which appear to be 4.7 Ohm 1 watt rated resistors. R4 and R5 get very hot as a result if you push the voltage .1V into balancing, but it's ok with the overal voltage tuned just below threshold. I'm running 10.4V for 4x 2.7V boost capacitors, and the cells are now staying in balance.

Q: 2 little Question: 1. square this one with ''2.7V500F Super Capacitor Two-pin 35*60 Farad Capacitor'' (also in ure shop)? and 2. can I the assambled 2 pieces connect in series with another one (should I mean,but asking before ist a better choice :))? But one more not easy Question : Do u know how much the self-discharging apiece is with this circuit ?Persent per day would be nice. TY

BG181117413 Yes, it's ok in series if you have multiple capacitors. Note that these start to balance at 2.85V, rather than 2.7V as advertised.

Q: how do i buy fast charging version?

BG181117413 It's working with QC 3.0. I've been able to power a TS80P via quickcharge at 9V 2.0A, by using the blue USB type A output on the power bank.
