Entry capacity
Where the 2.5Ah sits in the range
The compact XGT pack, and the only capacity in this series that stays under the 100Wh freight threshold, which makes it materially cheaper and simpler to ship than everything above it. Specified where the higher platform voltage is wanted for tool compatibility rather than for runtime, and where pack weight is the binding constraint.
At 90Wh this pack stays under the 100Wh threshold, which keeps air freight and passenger-baggage rules straightforward — the simplest capacity band to ship and to sell into retail channels.

Engineering
How this pack is built
- 01
XGT uses a 36V nominal architecture and its own interface; packs are not cross-compatible with 18V LXT tools.
- 02
Every capacity above 2.5Ah exceeds 100Wh, so air freight falls under fully regulated UN3480 rather than the relaxed small-cell provisions.
- 03
Cell selection and BMS thresholds sized for the higher bus voltage and the larger tools on this platform.
- 04
UN38.3 test summary and MSDS prepared per SKU, since the freight class differs across the range.
Every capacity in this series ships under your own label — artwork, housing colour, packaging and pack configuration are specified per programme.
