Thought I'd add my experience to this thread since it was useful to me in prep for receiving my shipment. I ordered (5) EG4 Lifepower batteries, the 6 level rack, and a few other items. Items were shipped via R&L "R|L" ("Residential / Lift Gate", I'm guessing). The driver arrived early (not an issue for me, but could have been for some else) and was pleasant on arrival. I immediately noticed compression damaged to the box on top as well as puncture damage to the side of one of the big boxes.
The driver was kind enough to bring the pallet up my driveway to my liking with his pallet jack. He handed me the 'customer copy' of the freight bill and was about to walk off when I ask him if I needed to sign. He told me no. I told him I'd noted some damage and pointed it out to him, and he told me that I was unable to make any notations on his paperwork. (Looking at the customer copy of the freight bill, I can't see any signature lines or notes area to make notes regarding damage.). I pointed out the damage and that I would receive the shipment but needed to note any damage before he left. He offered to wait while I checked each item in the shipment (5 eg4 batteries, a 6 slot rack, an a/c & dc disconnect, a charger and a few other items). there were 7 boxes. He did state that if there was no obvious damage to the packaging that there was no way the damage could have been caused during shipping and had to happen at the origin.. I didn't argue with him on this point.
Having read this thread prior, I was ready with a box cutter and opened every single box while he waited. He made no complaints. I mostly checked the front of the eg4 batteries ensuring there were no damaged posts, handles, or mounts. Despite the packaging damage, in my quick inspection (took maybe 5 mins to quickly check each item), I couldn't find anything wrong with the actual contents. I thanked the driver for his patience and he was on his way.
On further unpacking I did notice a minor dent & scratch on the side of one of the batteries (about an inch long with paint loss), but there was no damage to that side of the box and the foam packaging was intact. I chalk that one up to damage at the factory, since there's no way the scratch could have occurred with the box and foam intact. The battery powers up okay.
Not sure what the deal is with the driver not allowing me to sign the paperwork and note the packaging damage, but it does align with feedback earlier in this thread. It worked out okay this time. My scheduled delivery window was between 1-5pm. Driver showed up around 12pm. No call no text indicating early arrival. I was here and the earlier arrival actually worked out better for me.
Hope this helps someone as the feedback here has helped me.
