Develop ultra capacitor power supply and LiFePO4 battery power supply

[alazira]

Ian, how about these puppies? Could these work for powering an amp?

Hello Ian,

Hope you are safe and well. Could you give a project status update on the new version and when you feel it might be ready for purchase please?

I know all this takes time and you need to bed in and test and the wait is worth it

Interested to know how you are progressing and my super caps are already purchased

Thank you

Ian is ok, but very busy with producing medical ventilators, big order for Canada. Our toys will be ready for order next week.

GREAT to hear all is well!

Producing ventilators is MUCH more important than our toys and now it’s clear why he has been quiet on here

Well done Ian for all your efforts at this difficult time in the world

Thanks guys, Yes I'm really busy these days. But I still need time to take care my diyAudio projects.

I'll post some good news for you and trying to make them available soon.

Regards,
Ian

UcConditioner 5V design has been updated to V7.0 with big improvements.

1. Fully ultra low On-resistance MOS FET design. Get rid of relay.
2. Built-in constant current per-charge/charge circuits.
3. Built-in DC input detection and ultra capacitor monitoring circuits.
4. Control enable/disable conditioning automatically without any delay.
5. Control logic runs at back ground, no longer need any control signal. Just input and output. Really easy to use.
6. On-board active balancers to protect ultra capacitors.
7. Input: terminal connector and USB-C.
8. Output: terminal connector and USB-C.
9. With external ultra capacitor connector flexible for additional/external capacitors.
10. LED indications for power on, power good, ultra capacitor full and conditioning.
11. Double thickness PCB copper layer especially designed for high current and ultra low ESR applications.
12. MOS FETs controlled by optical isolators to eliminate any possible leakage current.

Testing result will be posted very soon.

Good weekend.

Does anyone have a part number for the rotary encoder on the LiFeP04 please ?

Please see the UcConditioner picture with ultra capacitors installed.

Ultra capacitors P/N:
BCAP0325 P270 S17
BCAP0350 E270 T11

Both of them are very good. But I prefer the first one a little bit because of the lower ESR. In real listening test, lower ESR ones also sound better.

The pins of ultra capacitors are very strong. Have to use iron with power 80W or higher to solder them on to UcConditionerPi PCB. It also because of the 2oz PCB copper layer.

However, to remove them from PCB would be a big challenge. So, if you are new to ultra capacitors, I would suggest using the external capacitor connector first. You could solder them to PCB only after you confirmed everything is OK.

Can't wait to try it :>)
