Any tips for connecting batteries in series or parallel?

Yes – fully charge each battery first. Use the same brand, model, capacity, and BMS, and buy them within 3–6 months of each other. For multiple connections, use a bus bar.

Can I use the battery right after delivery?

For shipping safety, it comes with ≤40% charge. Fully charge it before first use.

Can I use this battery on a boat?

Yes, as a service battery for things like a fridge or coffee maker. Keep it dry and away from water. Not for starting engines or trolling motors.

Can I charge or discharge it in cold weather?

Discharge works from -4°F (-20°C) to 140°F (60°C). But never charge below 32°F (0°C) – it damages the cells. The BMS will block charging. In winter, bring it indoors above 41°F (5°C) before charging.

Does the package include a LiFePO4 charger?

No. Please use only a dedicated 14.6V LiFePO4 smart charger. Using a regular lead-acid or other lithium charger can damage the battery.
