Q: What is the capacity of the LG LGDBD11865?

The LG LGDBD11865 has a rated capacity of 3,000mAh (11.25Wh at 3.75V nominal).

Q: What is the maximum discharge rate of the LG LGDBD11865?

The manufacturer rates the LGDBD11865 at 5.8A continuous discharge.

Q: How many LGDBD11865 cells do I need for a 48V ebike battery?

A 48V ebike pack uses a 13S configuration. With the LGDBD11865's 3.75V nominal, 13S gives you 48.8V nominal. A 13S4P pack (52 cells) delivers 12,000mAh (585Wh). That covers most 48V ebike applications.

Application suitability

PowerwallsHigh capacity means more stored energy per cell. Fewer cells needed for a given kWh target.

Ebike PacksMarginal. Check your motor's peak draw first. You might get voltage sag under load.

Car AudioNot enough discharge for car audio amplifiers. You need at least 15-20A continuous for most setups.

High-Drain VapingBelow the 25A Mooch CDR threshold that high-drain vaping needs. Use a higher-drain cell.

FlashlightsHigh capacity means long runtime. Great for everyday carry and extended use.

Power ToolsNot enough discharge or capacity for power tool use.

Handling and safety

Lithium cells can be dangerous if mishandled. A few things to keep in mind:

Never charge above 4.35V or discharge below 3V.
Store cells at around 3.6-3.8V (roughly 40-60% charge) for long-term storage.
Don't mix cells with different capacities, chemistries, or states of charge in a pack.
Inspect wraps before use. A torn wrap can cause a short circuit.
Always use a BMS or balance charger appropriate for your pack configuration.
Keep cells away from metal objects, keys, and coins. A short across the terminals can cause fire.
