Product Description
Two voltage ranges, two connector types — one charger that adapts to your entire battery fleet.
The Capacity.Li Adjustable Charger & Power Supply is a precision-built DC power tool for LiFePO4, Li-ion, LiPo, and lead-acid batteries. Available in four configurations — Model A (0–60V / 0–50A) for high-current fast charging, and Model B (0–120V / 0–25A) for wide voltage range coverage — it adapts to everything from small 12V starter batteries to large 48V/72V solar packs and e-bike systems. Both models feature constant-voltage / constant-current output, universal AC input, and built-in short-circuit protection for safe, reliable operation.
Why Choose Capacity.Li?
High-Current Fast Charging
Model A delivers up to 50A — ideal for large-capacity 12V/24V batteries where charging speed matters. Cut downtime in half.
Wide Voltage Coverage
Model B reaches 120V — one charger for 12V through 96V battery systems. Solar arrays, e-bikes, EV packs, all covered.
Universal AC Input
AC 100–240V auto-detecting. Works with EU, US, AU, and UK power outlets — no adapter needed, anywhere in the world.
Multi-Chemistry Support
LiFePO4 (1S–4S), Li-ion/Lipo (1S–3S), AGM, Gel, VRLA, and flooded lead-acid. One charger for every battery type.
Built-In Safety
Short-circuit protection with automatic constant-current mode. Reverse polarity safeguards in battery charging modes.
Factory Direct Warranty
2-year warranty, 30-day money-back guarantee, free shipping, and lifetime technical support on all models.

Which Model Is Right for You?
| Scenario | Model A (0–60V / 0–50A) | Model B (0–120V / 0–25A) |
|---|---|---|
| Fast charging 12V / 24V batteries | ✓ Best choice — up to 50A | 25A max per battery |
| Single charger for many voltages | Covers 12V to 48V | ✓ Best choice — covers 12V to 96V |
| 72V / 96V e-bike / EV battery packs | Max 60V — not suitable | ✓ Full range up to 120V |
| Solar / off-grid 48V LiFePO4 systems | ✓ High current for larger banks | ✓ Wide voltage headroom |
| Lead-acid (6V / 12V) recovery charging | ✓ 50A for faster recovery | 25A works, but slower |
| DC power supply mode (constant V/C) | ✓ Higher current capacity | ✓ Wider voltage range |
Three Output Modes
Built-In Safety Protection
Note: Always verify positive (+) and negative (−) connections before use. Red = Positive, Black = Negative. Reverse polarity may cause damage.
