Biggs... two points after I first state that I know nothing of this company directly.
1 When you compare these to other AGM batteries...are you looking at the physical size and weight??
VOLTS 12V AMP HOURS 155AH WEIGHT 90LB SIZE : L=13.5" W=6.8" H=11.3" MAX.
CHARGING CURRENT: 35A MAX. CHARGING VOLTAGE: 14.7V
Make sure you are comparing like batteries. This does NOT compare with the sizes commonly found in stores and installed in RV's...typically group 24, 27 AND 31 WHICH
ARE SMALLER and typically offer 75/90/105 amp hours respectively nd weigh in with much less lead. The tanks more closely resemble Trojan 1275s http://www.trojanbattery.com/pdf/T12...t_DS_Final.pdf
2. This brand has been around for less than 5 years. I can find NO manufacturing facility and the home "office" looks like this:
Obviously they are slapping a label on someone else's battery. Source unknown...perhaps China?...What are the STANDARDS they use in testing their claimed performance?
So...ya takes yer chances AND you better make sure 2 will fit where your existing batts now sit. See my post above for comments on how long AGM's last and the reasons for the price difference with AGM's and the SAME SIZE flooded battery.
