LIPO Trick 2: Setting Up a LIPO VOLTAGE CLAMP

Find the best swithcing regulator power supplies with the best wide range adjustment regulator board that has a ten-turn pot voltage adjust, most will only have a single turn pot adjustment

I use the 400W QUALIDYNE model no: 02003 F becuz it has a dualie 12V output at 7 amps and 15 amps monitored with whattmeters so I can read the ZERO charge current when done. I use this to charge 8 packs sometimes setup for 2S and 3S packs

I also found a 24V 4.2 amp switcher for a 6S pack ( 25.2V )

Using them is pretty simple: fly your lipo packs only ~70% duty cycle ( example, 40 amps instead of 56 amps on a TP 8000 7C gen 1 pack ) and charge them back up when the pack voltge is high, if U fly them too low then U will have to precharge them back up ~ 4V per cell using any charger with a CURRENT adjust

The output of a VOLTAGE CLAMP is set open circuit with no-load connected using a DVM or whattmeter

I would to hear about any other brands of swithchers like the QUALIDYNE made by Lamda
