AOKLY 12V 300Ah LiFePO4 Battery with Bluetooth, 200A BMS, 15000+ Deep Cycles, 3840Wh Low-Temp Cut-Off, Lithium Battery for RV Solar Marine TrollingMotor Off-Grid Backup Power Home Energy

This is the cheapest 300ah battery I could find. I replaced my old RV lead acid batteries with this single battery. It is a great addition to the RV. I added a 12V air conditioner and it runs the A/C for over 12 hours. It also powers everything else in the RV that isn't 120V. So far it's awesome and I would definitely buy this battery in the future if I plan to expand.

This battery clearly states it is a 300amp battery and will give 3840 watt hours. That's why I bought it. As soon as I started up the Bluetooth connection it says that it is only 200 amp hours. THAT IS FALSE ADVERTISING !! If it wasn't for the fact I needed it for my solar setup then I would have returned it. I had already used it for a week before I realized it had Bluetooth. That is the only bonus of this battery. No instructions claimed it had Bluetooth and the sticker in the advertised shows it to be 300 amp with 3840 watt hours but my battery has NO sticker anywhere except for the scanner square that connects the Bluetooth. If I didn't need it I would send it back.

Tested with a DL24 battery tester and the total capacity is only 78% as claimed of its listing, see the attached photo. When buying this item from walmart.com, the return policy -> Returnable to store? Yes, but now try to initiate a return process since its capacity is overrated, the webpage shows contact seller which we did but have not received any response over 72 hours. So before clicking the buy button, think more than twice, this item's capacity is far below it claims. You have been warned!!!
