Charging rules

Charging window 13.8 – 16.0V. At this size the alternator recovers the bank between hits — it does not run the system. Ships at roughly 30% state of charge; bench-charge before install. Full details on our Support page.

Charging windows & pairing.

Every pack has a voltage window it lives in. This chart is zoomed to the KILO HP 200 so you can see at a glance what it shares a bank with — and where to set your charging system when it does.

How pairing works

Read the chart. Red is where this pack is outside its own window. Another chemistry can share the bank only where its bar crosses the clear area — the yellow band — and the charging system must sit inside it. Set it at the white marker, the top of the band: at the bottom of the band the pack with the higher floor is undercharged and never reaches rated output; above the top the pack with the lower ceiling is past its hard limit.

Sodium ion is the only chemistry that mixes. Lithium chemistries (LTO, LiFePO4, NMC) are never banked together — that is unsafe, and we do not support it.

On any bank: matched cable lengths so the packs share evenly, and bring every pack to a similar state of charge before connecting.
