I have 28 of these. This is a copy directly from the eBay listing I have for these batteries.

For sale is one Powerizer 12v 14.8v 30000mah PR-CU-R574 Lipo battery. This battery was used for only a few cycles in a prototype environment and is ready for resale.

The grey 3-pin connector is a constant 12v output from a 12v DC-DC buck covnerter. The 2-pin Molex connector is the charge/discharge connector for the battery. The green PCB is the buck converter and the red PCB inside the battery is the BMS.
These batteries can be taken apart, or used as-is. Each battery pack contains twelve 3.7v 10000mah lipo cells and a 14.8v to 12v DC-DC buck converter to limit the output voltage to 12v. This Buck converter has a buzzer that sounds when the battery pack approaches a low voltage. Testing revealed these battery packs to still retain 80-90% of their original capacity.

$20 each if you pickup locally and pay in cash. I am located in Southeastern Michigan.

$30 each + shipping if you would like these batteries shipped to your door.

Firm on price.

Shipping to the lower 48 states only.

Since i'm not allowed to leave contact information and I don't come here often, I will be checking up on my account every 2-3 days. So expect a delay answering your initial PM. Thanks.

pm me back if you still have some of these. I need 4 of them to make ~56volts. I will need them shipped to Oregon.
