SolarMax SM-LFP-12100-ECO 1.28kWH Lithium Ion Battery 12V 100Ah

The latest SolarMax SM-LFP-12100-ECO 1.28kWH Lithium Ion Battery 12V 100Ah price in Pakistan is Rs. 58,000/- updated on August 29, 2026.

Overview:

The SolarMax SM-LFP-12100-ECO is the value-tier version of the SM-LFP-12100, sharing the same 12.8V, 100Ah, 1.28kWh core specification but built to a lighter, more cost-focused design. Where the standard 12100 uses a metal case and carries a 3-year warranty, the ECO uses an ABS plastic case, weighs roughly 5kg less (10.5kg vs 15.5kg), and is backed by a shorter 1-year product warranty.

Cycle life is rated at ≥3,500 cycles at 80% depth of discharge — lower than the standard model’s 6,000+ cycle rating, which is the main trade-off for the reduced weight and price. Charge and discharge current limits, charge voltage (though set slightly higher at 14.6V vs 14.2V), and temperature tolerance all match the standard 12100 closely, and the ECO retains the same built-in Bluetooth monitoring.

This makes the ECO a reasonable choice for buyers who want genuine LiFePO₄ chemistry and SolarMax’s protection stack at a lower price point, provided the shorter warranty and lower cycle count fit the intended use case — typically a lighter-duty backup role rather than daily deep cycling.
