Installation notes

Before you install.

Open a question for model-specific guidance and sources.

Verified against the manufacturer's documentation (rev. Gen2 Seat Base specification May 2025; Drift Range manual August 2026), checked 2026-10-01. Manufacturer documentation →

Which Gen2 battery is covered?

The Seat Base 230 Ah is a 12.8 V battery rated for 250 A charging and discharging, according to its model-specific sheet. Do not substitute the upright Gen2 230 Ah battery’s 300 A specification. The 275 × 315 × 187.5 mm metal case includes heating, Bluetooth and active balancing.

What must be checked before connection?

Secure the battery under the seat while preserving clearance for terminals, seat mechanisms and service access. The August 2026 range manual recommends leaving discharge disabled during installation and limiting each post to two cable lugs; use busbars for more connections.

The current Seat Base product page identifies M10 terminals, matching the Gen2 range manual. Use the supplied hardware and correctly fitting lugs. The manual recommends 6 Nm, within its stated 4–8 Nm range; do not stack more than two lugs on a post.

How are charging and heating configured?

The Seat Base sheet specifies 14.4 V bulk, 13.5 V float, with 14.6 V maximum charging voltage. Its heater uses incoming charging power; a cold connected charger can warm the cells before current enters them. It is not continuous heating powered from the stored battery energy.

How do you commission it?

Check polarity, external fuse/disconnect sizing and total charger output, then enable discharge using the unit’s button/app. An apparent 0–2 V at the posts can mean discharge is disabled. Check BMS status before diagnosing a failed battery. Battery-link ports carry communications, not parallel-bank current; every battery still needs its own correctly sized power connections.
