I purchased this battery in October 2024 in preparation for campervan build. By the time I was getting ready to do the install the specifications had changed and I needed a different format battery (24v). So this is a completely new, unused premium LiFePo4 battery with self-heating and Bluetooth. It also includes the hold down brackets. You have to pay at least $619 (+tax) to get the same battery from Renogy direct. I only opened the box to put a lithium charger on it to ensure it was good (had +90% SOC). Look up all the details at Renogy.ca • 2-in-1 12V 100Ah LiFePO4 battery with self-heating and Bluetooth. • Double active protection system ensures maximum safety for your battery. • Flame-retardant casing prevents vertical burning within 10 seconds. •Secure your batteries with mounting holes & battery fix brackets. • Waterproof, dust-proof (IP67), and corrosion-resistant (ISO). • Note: Only Supports parallel connections for up to 8 units, for expandable storage.
