  • Solid good working 165AH batteries running in parallel for 330AH for RV dry camping
Size: 2 Pack Style: 12V 165Ah Bluetooth
Bought two of these to run in parallel for camper power. So far so good 2 months usage. In parallel the BMS says 1 battery is 100% and the other is drawing down but I believe that is just the BMS trying to figure out a parallel battery set up. Two of these 165AH batteries gets me an easy 4+ days with 12 vdc fridge in the camper heater and water pump usage and minimal solar ending up with 60% battery level after 4 days of camping (dry camping no electric). ... show more

  • Good Batteries
Size: 2 Pack Style: 12V 165Ah Bluetooth
I have 2 of these wired in series that I use with my Minn Kota Terrova 24v trolling motor. I have been using these for a few months now and have yet to drain them during a day of fishing. The bluetooth feature is nice because it lets me see how many amps my trolling motor is pulling and it lets me see how many hours of use I have left in the batteries as well. I typically troll with my Terrova and at about a 7 speed and autopilot enabled, the app says I can get about 7-8 hours of use. The screen shot is from when I just installed them and was pulling minimal amps from my trolling motor, but wanted to share what data the app will give you. ... show more

Size: 1 Pack Style: 12V 165Ah Bluetooth
We’re loving this battery. My spouse converted our RV house battery from an acid to this ion….. all I can say is it has made a huge difference! If we stop and need to stay unplugged for a couple of days this battery will at least keep the fridge running without having to hookup to electric or generator to recharge it. (without solar). ... show more

  • Hit and miss
Size: 1 Pack Style: 12V 165Ah Bluetooth
Hit and miss. First one charged to full capacity and works good so far, second one wouldn't even charge to full capacity. Returned, and third one charged and works so far. Zero clue on longevity. Customer service was good. Sent return label quickly and refunded for returned battery next day. The returning of the battery and refund process was impressively good! ... show more

  • This battery is great.
Size: 1 Pack Style: 12V 165Ah Bluetooth
This battery is the ticket. I don’t know how it stores so much Entergy. It works for hours and still keeps going. The battery this one replaced could not even start to last as long as this one does. It was not worn out either just not on this batteries level. Still using the other one on a better fit for that battery. I just wish I did not wait so long to change my way of thinking from AGM to Lithium big difference for the better so far anyway. I would surely buy this one again when I need to replace it. ... show more

  • Pleased with purchase at this point .
Size: 4 Pack Style: 12V 165Ah Bluetooth
Batteries shipped quickly came 50% charged top off charge using smart charger then installed in boat , haven’t had time to really put them to the test as far as how well they hold up on all day fishing but they are definitely lighter weight wise than any AGM or deep cycle battery and that makes installing in tight places much easier. ... show more
