Yes. Just add the amp loads together and keep the total under the limit of the power supply.

Cool, Thanks. So if I am charging 2 sets of TP 6S3PL 6000 (2x 3S3PL 6000 in Series) at 4.5 amps each (9 amps total). I should be ok with the 13.6V @ 12.5 Amps limit of the power supply? Thanks! David 






No, I meant the amp draws of the battery chargers. It takes a whole lot more current into your charger than what comes out to charge 6S packs, because of the big stepup in voltage.

6 x 4.2 volts x 4.5 amps = 113.4 Watts for one pack. Add about 15% for losses and you need 130 Watts. 130 Watts/13.6 volts = 9+ amps per pack. Bill

LOL, Great job of completely confusing me Is that 130watts per charger or do I split it between 2 AF 109s so each one needs 65 watts? I am not big on electrical theory (if my hair stands up on end, then I have touched the wrong wire, is the extent of my knowledge) So do you think I can attach 2 astro flight 109, to the power supply and charge two of these 6s3p 6000 @4.5 amps at one time without burning down my house Thanks!

Ok, so after reading your post again, I think I need a 13.6 power supply with 19 or so amps to charge both of these packs with 2 109s or I should just get another power supply with the 109. Is that right? David 






You can:
1. Get a second power supply for the other charger. 2. Get a bigger power supply to run both chargers. 3. Use your existing setup at a lower charge rate.
