I have used my Hitec X2 charger to charge my lead acid battery.. Just set it to the lead acid (Pb) setting, then set it for 6s (12 Volts) and if your charger is like mine, it won't go any higher than 5 amps.. Even then, it will only charge the battery at the rate that the charger decides is best for your battery.. Personally, I wouldn't charge my lead acid battery any higher than C/10 in your case, I wouldn't charge a 7 Ah cell any higher than .7Ah, 1Ah Max!!
