Check four things: the connector’s current rating against the pack’s continuous current, the mating half on the truck and charger, the cable cross-section, and keying so that the wrong voltage cannot be connected. Redway’s 48V 600Ah pack, for example, lists a Rema 320A charging connector and an Ande

Expect six stages: requirements and RFQ, engineering proposal and drawing, sample build, lab and on-truck testing, a pilot batch, and series production with change control. The buyer signs off at four points: the specification, the drawing, the tested sample and the pilot batch. Keep each approval i

Build two tiers. Your own first-line team answers common questions from a fault guide in your time zone, and passes only real faults to the factory with a fixed data pack: photos, BMS readings, charger model and a short video. Agree response windows, channels and a shared case log with the factory i

Agree a written outgoing checklist per model, run on every pack and recorded against its serial number: visual and label check, open-circuit voltage, a BMS function check, communication with the display or app, the burn-in test before shipment, and a packing check. Type tests such as vibration, shoc

Train three groups differently. Operators need charging rules, the meaning of the display and alarms, and what to do when a truck stops. Technicians need BMS data reading, connector and cable checks, safe lifting and isolation, and the supplier’s fault procedure. Supervisors need the escalation path

Start with three limits from each truck: compartment dimensions, the minimum battery weight on the data plate, and the controller’s current. Then choose capacity from measured energy use per shift. Redway lists 24V packs from 50Ah to 560Ah; for example, the 24V 280Ah pack is 25.6V nominal and 7.16 k

Most of what the customer sees can carry your brand: the logo on the battery shell, the rating label, the display start screen where one is fitted, the user manual and the packing. What should stay traceable to the factory are the serial numbers, cell and BMS records and the test data behind your re

Price differences usually trace to nine drivers: cell grade and brand, capacity and voltage, BMS and communication options, enclosure and construction, order volume and mix, OEM customisation and labels, documents and test reports, freight terms, and payment and warranty terms.

Build a private-label range in four layers: a fixed specification and BMS settings for each model, label and manual in your name, documents and test reports you can pass to dealers, and a warranty and support chain that you control. Redway offers silkscreen, label, laser logo and user manual options

Check from outside in: mains supply and breaker, the charger’s display or fault code, the connector and plug, pack voltage, pack temperature, and then BMS fault data. Swap with a known-good charger or pack only after isolating the pack from the fault. Do not bypass the BMS or force charge a pack tha

Plan from energy, not from habit: measure kWh used per truck per shift, compare it with what the pack and charger can add in each break, and size chargers and plugs accordingly. For example, a 150A charge into a 51.2V pack is at most about 7.7 kW, so a 30-minute break adds at most about 3.8 kWh, and

Match five things: nominal voltage, charge profile, current limit, temperature window and communication. A 48V LiFePO4 pack is 16 cells in series (51.2V nominal, 58.4V maximum charge), so the charger must be a constant-current, constant-voltage profile set for lithium with an end voltage the pack’s
