Pulse style fast chargers are meant for batteries of 12AH or greater with an oxygen recombination discharge cycle. I guess I'll try to look for mfg specs, but they arent so easy to find.
Keep in mind 10A charger / three batteries is 3.3A. I guess my question related more to ..
Can I charge these in parallel okay? I feel like it should be safe (safer than charging in series where the voltage is above spec).
