Antigravity AG-1201 Lithium Battery

Title explains most. Battery wouldn't hold a charge very long after it arrived. No power draw and im in Florida with no cold at all, so it was defective. Amazon made it difficult to provide a return but the company themselves were kind enough to send me a new battery to replace the one that isn't working. Currently waiting for it's arrival and hope all goes well!

There is no BMS on these batteries, which is insane to me given the MSRP of the battery (especially for 8 ahs actual) vs how cheap BMS circuitry is. They claim a year with no charge (if no parasitic voltage exists - mine has none) but mine didn’t last a mild Oklahoma winter (rarely below 32 degrees F) of 2-3 months. For the cost of the battery, the known fact that lithium batteries are fragile to their voltage ranges, and the fact that it will go to zero volts with no protection is wild. It smacks of a company that simply doesn’t care to put in the extra $10’s to protect their customers.
