Re: ELTEK Flatpack2 48/2000 (eaton alternative)

No, these can not do 60v. You could use a boost converter. Or try this model, if you can find one. https://www.eltek.com/products/flatpack2-603000-she/

Re: 900w12v boost charger

This is the way I calculate the output. I’m happy to be corrected. This boast converter has max 'input' of 15A. You’ll lose about 15% in efficiency. So 15A x 41V x 0.85 = approx 522w output. So probably safe at 500W. Other considerations: - The closer the output voltage is to the input…better the ef...

Re: KT controller short circuit fault on a solar trike

Probably a different issue but...I've found my KT controller sometimes shuts down in 5 minutes based on the L4 parameter "delay time of automatic shutdown" when PAS is not collected and using throttle only. If this is the problem, then this can be changed to 120 minutes as a workaround.

Re: I think my new charger Burn out my DC Converter

Your old charger is 56V max output voltage for Lead Acid. The new charger is 54.6V for Lithium battery. So doesn’t look like the right charger. It should have just under charged the battery. But as you say, maybe the 1.6A vs 2.5A output has burnt something out. If I'm reading it correctly the pin or...

Re: concerns about lipos

Test the individual cells on one pack via the balance leads with a multimeter. If they are all the same voltage on the pack, your buzzer is likely the problem.

If they are different voltages you could have faulty charger, connector, wiring or cell.

Hi jean0, You're getting 0.36v as the DC output? For a 48v unit you should be getting 53.5v as default when connecting AC (with CAN disconnected). Alternately, the unit could be programmed for another default voltage within 43-5v-57.6v. Some units don't calibrate well, so if the voltage is programme...

I would have assumed these chargers would not be DC isolated? If they are DC isolated, then they will probably work. If they are not DC isolated, then they will short out?

Re: ULtra Compact 1800W charger + Eltek programming

Hi Camon, This code should set your flatpack temporarily to 50.2v and 14a. You need to change the serial numbers in two places. Upload to Arduino Leonardo and power the Arduino off/on. Then use the serial monitor to see status Example 04 1A 00 00 A3 13 F1 00 2C Temperature = 26 Current = 0.00 Output...

Re: Cycle satiator, EM3EV Battery charge

that's a 14s battery. So set Satiator for 100% full charge to 14 x 4.2v = 58.8v
Set to maximum Amps for Satiator to 8A. That large pack should easily take it. Satiator will automatically limit to 360w / battery-voltage. Approx 6.5A give or take.
