Built for off-grid hobbyists and van builders who need to verify real-world storage capacity before committing to a full power bank. Not for enterprise-scale installations — this shop focuses on budget-friendly 12V builds and DIY testing setups.
This is the most critical tool here because budget LiFePO4 cells are notorious for variance. You cannot trust the sticker on the case; you need a hard discharge test to confirm you actually got the 100Ah you paid for.
⚠ Worth knowing: These 12V 100Ah units are often built with Grade B cells to hit this price point, meaning they likely won't hit their rated cycle life if you consistently discharge them below 10%. Keep your depth of discharge conservative to avoid early cell drifting.

What to know
Performing comprehensive capacity tests can be time-consuming, as discharge cycles for 100Ah batteries may take several hours or more to complete.
The initial investment in testing equipment can be significant for a one-time user, though it offers excellent value for those frequently needing to test batteries.
How to use this together
1
Charge the Battery
First, fully charge your 12V 100Ah LiFePO4 battery using the 12V 10A LiFePO4 Battery Charger. A complete charge is crucial for accurate capacity testing, ensuring the battery starts at its maximum potential energy. This step prepares the battery for a controlled discharge.
2
Connect the Electronic Load and Monitor
Next, connect the DL24P 150W 20A DC Electronic Load to the fully charged battery. Simultaneously, integrate the TK15 High Precision Battery Coulometer with its shunt in series with the load. The coulometer provides real-time data while the DL24P handles the controlled discharge, allowing you to accurately track dispensed capacity.
3
Perform the Capacity Test
Set the DL24P to discharge the battery at a constant, appropriate C-rate (e.g., 0.1C to 0.2C for LiFePO4, or 10A to 20A for a 100Ah battery). Monitor the TK15 Coulometer to track the total amp-hours (Ah) discharged until the battery reaches its lower voltage cut-off (typically around 10V). This process directly measures the usable capacity.
