1

Size by shift, not by sticker

Add the amp-hours your machine actually pulls per shift, then add 20% headroom.

2

Plan the charge window

Lithium accepts opportunity charging, so a lunch-break top-up counts toward the shift.

3

Standardize the fleet

Running one voltage and one charger type across machines cuts spares and training.

Fleet questions

Heavy equipment FAQ

Can lithium run multiple shifts?
Yes. Lithium delivers close to full rated capacity and accepts opportunity charging, so a short break top-up can carry a second shift.
Do I need a new charger?
Yes. Lead-acid chargers cannot complete a lithium charge profile. Match the charger to pack voltage.
What maintenance is required?
None of the lead-acid routine — no watering, equalizing, terminal cleaning or acid spills. Keep terminals tight and connections clean.
How do the packs behave in cold storage?
The BMS blocks charging below safe temperature, and high-tier packs add internal heating so they can charge in cold buildings.
Is fleet pricing available?
Yes. Contact us for volume pricing, dealer terms and lead times.
What warranty applies?
Promise series packs carry a 10-year warranty with US-based support.
