Shopping at ShopSolarKits was great!
My 48V BDGR kits were shipped by truck across the country, over 3000 miles! The BigBattery shipping packages were great, arrived faster than expected, but there were some problems inside the steel BDGR boxes. I was able to contact BigBattery and we quickly take care of the problems.
I have the BDGR packs connected to my small solar back-up system (replacing 240 lbs of old lead-acid), and I'm in the process of testing their performance. So far, the BDGR packs (Generation 2) are working fine.
