A123 racing batteries and TP balancers
I have 2 A123 Racing packs I purchased from Horizon Hobby. They only have one (orange lead) pig tail coming off the battery to balance. This allows you to plug into the A123 Racing 10amp charger (too much money to not have a digital display). I took the batteries apart and soldered TP balance leads on them and put them back together. You can also create a customer balancer cable by running the TP white cable to the orange balance lead. TP Black cable to the battery negative lead and TP Blue cable to the battery positive lead. Both TP 205 and 210 balance these batteries well.
