Slimline Van Life Batteries

Source 70–100 mm depth LiFePO4 packs for camper van conversions and van builders. Boundless Battery OEM 12V–48V slimline trays with Bluetooth BMS and custom terminal layouts.

Tray Depth, Floor Space, and Van Layout Constraints

Camper conversions lose usable floor area when standard Group 31 packs exceed bench or wheel-well depth. Boundless Battery builds slimline LiFePO4 modules from 70 mm to 100 mm for under-seat, galley, and garage trays. We match terminal orientation and strap points to popular van platforms so installers avoid last-minute rerouting.

12V, 24V, and 48V Platforms for Van Builders

Van builders spec 12V house banks for lighting and refrigeration, 24V for inverter-heavy builds, and 48V for compact high-power layouts. Our OEM team configures series-parallel cell maps, fuse locations, and BMS CAN or Bluetooth telemetry for fleet and one-off builds. Voltage platform selection is documented with load tables for dealer and installer quoting.

Thermal Management in Enclosed Van Compartments

Slim packs often sit against insulated walls with limited airflow. Boundless Battery validates charge and discharge derating for enclosed installs and offers optional temperature probes tied to BMS limits. We share mounting guidance that preserves service access without compromising crash-zone clearances on OEM van programs.

Private Label, MOQ, and Builder Support Programs

Van conversion brands need consistent SKUs, co-branded datasheets, and warranty flows that scale from prototype to production. Boundless Battery supports private-label slimline packs with MOQ-friendly pilot runs and engineering review of tray drawings. Technical support covers charger compatibility, alternator DC-DC profiles, and export certificate bundles per SKU.

Slimline LiFePO4 vs Standard Van Battery Trays

Factor	Slimline LiFePO4 (OEM)	Standard Deep-Cycle Tray
Compartment depth required	~70–100 mm low-profile trays	~150–200 mm typical boxes
Usable Ah per volume	Higher cell-pack density for OEM builds	Lower density; more dead space
Custom B2B form factors	Length/terminal layouts per van platform	Limited catalog sizes

Industry Pain Points We Solve

Standard lithium packs exceed 120 mm depth and force raised floors or lost storage
Van builders cannot source documented 70–100 mm LiFePO4 with matched BMS limits
Generic slim packs lack correct terminal layout for popular conversion tray templates
Unclear 48V slim options delay inverter-centric build schedules
Slow OEM engineering response misses seasonal van show and fleet launch windows

Frequently Asked Questions

What depth range defines a slimline van LiFePO4 pack?

Boundless Battery targets 70 mm to 100 mm module depth for under-seat and wheel-well trays. Exact dimensions depend on capacity, terminal hardware, and enclosure spec—share tray drawings for a fit review.

Which voltages do van builders typically order?

12V house banks remain common; 24V and 48V slim packs support higher inverter loads with smaller cable runs. We configure 12V, 24V, and 48V OEM layouts with documented fuse and BMS settings.

Can slimline packs handle alternator charging from the van engine?

Yes when DC-DC profiles and BMS charge limits are validated for your alternator and wire gauge. We supply integration guides for split-charge and multi-input systems used in conversion builds.

How much capacity fits in a 70 mm deep tray?

Capacity depends on cell format and length. Many 100–200 Ah usable layouts fit 70–85 mm depths; higher Ah may require 90–100 mm or dual slim modules in parallel—engineering quotes per tray size.

Do you offer Bluetooth BMS monitoring for van installs?

Bluetooth SOC, cell balance status, and fault codes are standard options on slimline SKUs. CAN bus interfaces are available for builds integrating with Victron, Renogy, or custom dashboards.

Are slimline packs safe under van seats and beds?

Enclosures and mounting must respect OEM crash and ventilation guidance. We document torque specs, clearance, and BMS temperature limits for enclosed compartment installs.

Can dealers private-label slimline van batteries?

Yes. Custom labels, color bands, retail cartons, and co-branded install guides are available with MOQ-friendly pilot quantities for van conversion brands.

What certifications apply to van LiFePO4 exports?

UN38.3 transport, IEC 62619 for industrial packs, and customer UL pathways as required. Certificate bundles ship per SKU for customs, insurers, and fleet compliance reviews.

How does cold weather affect slim van installs?

Low temperatures increase internal resistance; BMS may limit charge until cells warm. We provide derating guidance and optional probe placement for northern conversion markets.

What MOQ and lead time should van builders expect?

Pilot MOQs support tray validation and show-season launches. Share build forecasts before peak conversion season to secure cell allocation and production slots.
