yes I'm going to do a combo pack of these nine year old cells I admitted or remove 4 cells from one pack. So 12s and 8s lifepo4 cells ok. I have two una 9 Plus + Max 300 watt chargers through the sense wires 12 volt to 14 volt input. The the power supply is a 12.6 HP DPS 600w power supply close to 12.6v volts output. It has two wires and two red wires and black wires. The guy who sold it to me said I can hook up two chargers and it will work . so I'm thinking of charging the 6s on one battery and the 4S on the other battery at the same time and have none of the batteries connected or maybe I could have the red from one battery and a black from another for 72 volts and never have to disconnect that once it sits on the bike. With the red positive not connected to the controller at the time of charging.16362504435765075486619366811004.jpgmultiple chargers.
 
I have a extra red and black output wires that I've never used on my 600 waat HP power supply to power my two 300 watt balance chargers. At 5amp. I wonder can I put the 2nd 300 w battery charger una9 plus+ connected to the same HP 600 power supply to two different batteries
 
Sorry I was on the trail I cleaned up the first and second message so it read right I was doing talk-to-text and it was getting cold out here.
