Industry Trend: Battery Costs Expected to Rise from 2026

Cell Price are set to rise more than 20% in 2026 due to China policy changes.

China is tightening export support for solar and battery products by reducing and phasing out export VAT rebates, while upstream cell material costs are becoming more volatile. In simple terms: the policy tailwind that helped keep export prices ultra-low is fading, and cell costs are more likely to move up.

Active Balancing vs. Passive Balancing

Passive Balancing Is the Right Choice for an Engineering-Grade, Commercial Battery Pack.

In DIY battery communities, active balancing is often seen as “better” because it can correct large imbalances quickly—something DIY builds frequently suffer from.

But for commercial, integrated battery packs built with controlled cell sourcing, factory matching, and validated pack design, passive balancing is usually the more appropriate engineering solution: simpler, more reliable, and fully sufficient for the type of imbalance that occurs in properly built packs.
