This guide explains the possible reasons why a SOK LiFePO₄ battery may not charge after deep discharge and provides step-by-step solutions to help resolve the issue.

In DIY solar communities, one debate keeps coming back again and again: Are lead-acid batteries actually more cost-effective than LiFePO4? A user on a DIY solar forum once shared a fairly typical side-by-side calculation. At first glance, lead-acid looks like the cheaper option. But that comparison only tells part of the story. The Original DIY Comparison The assumptions were: Inverter efficiency: 82% Lead-acid usable DOD: 50% LiFePO4 usable DOD: 85% 🔋 Flooded Lead-Acid (FLA

This guide helps you quickly diagnose and solve the most common issues with the SOK 12V 100Ah LiFePO4 battery (SK12V100H), including voltage readings, Bluetooth connection, charging issues, and storage behavior.

After a few years of non-stop price drops, the lithium battery market in 2026 has thrown everyone a curveball. If you’ve been shopping for a battery lately, you’ve probably noticed the price tags creeping back up. This isn’t just noise. From what we’re seeing in the supply chain, the cost structure behind LiFePO4 batteries has genuinely changed again. So let’s break down what’s actually driving this, based on what’s happening upstream—not just headlines—and what it means if y
