Battery Equalizer
A high-current equalizer moves energy between cells fast enough for large packs. It is the same job as a small balancer, sized for cells a 2 A unit cannot correct in a reasonable time — or for a pack that has drifted far enough to need recovering rather than topping up.

What decides a battery equalizer
3 parameters, in the order they eliminate options. Each one can rule out a model on its own — which is why the order matters.
1 · Pack capacity
Balance current has to be meaningful relative to cell capacity. On large cells and large packs a small balancer still works, but correcting a real delta takes days; the high-current class does the same job in hours.
2 · How far the pack has drifted
A pack that is healthy and drifts slowly does not need more current — it needs to be balanced regularly. A pack that sat unbalanced for months, or was assembled from cells at different ages, is the case where current decides whether recovery is practical at all.
3 · Where the unit will live
Higher current means more heat and a larger enclosure. A unit that has to sit inside a sealed battery box is a different choice from one used on a bench to bring a pack back.

Delivery is included in the price for 25 countries, and nothing is added at checkout. Ten units in a mixed order move onto a different cost tier.
Lead times are not published yet
Delivery times depend on the carrier contract, which is still being quoted. We would rather leave the number out than publish one we cannot hold — an unfulfillable delivery promise causes more cancellations than a missing estimate.
