ACOPOWER 12V 100Ah LiFePO4 Deep Cycle Lithium Battery: Frequently Asked Questions

Can I charge it in freezing weather?
No. ACOPOWER rates charging from 32°F to 122°F (0°C to 50°C). You can discharge it down to -4°F (-20°C), but charging below freezing is outside the published range, so keep it somewhere that stays above 32°F while it charges.
How big is it and how much does it weigh?
ACOPOWER does not publish dimensions or weight for this battery on its product page. Call (303) 876-7654 and we'll get the exact size and weight before you order.
Can I connect several in series or parallel?
ACOPOWER does not publish a series or parallel limit for this model. Call (303) 876-7654 before you wire multiple batteries together and we'll confirm.
What is the warranty?
ACOPOWER's warranty policy covers its products other than solar panels for 1 year from the original purchase date, while some ACOPOWER lithium battery manuals reference a longer replacement term. Because the terms differ, we'll confirm the exact warranty for this battery in writing before you order. Call (303) 876-7654.
Can I install this myself, or do I need an electrician?
Small 12V systems are a common DIY project, but any wiring to a battery bank, inverter, or your home's electrical system should follow the manufacturer's manual and local electrical code. If you're unsure, a licensed electrician or solar installer is the safe choice — call (303) 876-7654 and we can help you figure out what your setup needs.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Lowest Price Guarantee applies — if you find this product cheaper at another authorized ACOPOWER dealer, call us at (303) 876-7654 before you order and we'll take care of it.
