Use your own data in a simple model: compare total cost per truck over the same period for both options, then divide the extra upfront cost of lithium by the yearly saving. Collect the inputs first (purchase price, expected life, energy use, labour for watering and battery changes, spare batteries a

Sea is the normal choice for heavy forklift packs; air is rarely practical; road is used for the inland legs. All three treat a lithium-ion pack above 100 Wh as Class 9 dangerous goods (UN3480). For air, the standard instruction limits a package to 35 kg net and 30% state of charge, which a pack of

Walk the path of your order from receiving to shipping, and ask to see a live order and its records at every stop: cell storage and sorting, pack assembly, BMS programming, charge-discharge and safety testing, burn-in, final inspection and the dangerous-goods packing area. Send the agenda and a docu

Check both volume and payload, because for heavy packs payload can be the limit. Using the 51.2V 105Ah figures on Redway’s 48V 100Ah golf cart page (500 x 355 x 247 mm, 43.2 kg), one bare pack takes about 0.044 m³. A standard 20ft dry container offers about 33 m³ and 28,200 kg payload, a 40ft about

Agree six things in writing before production: where each brand element goes (silkscreen, label or laser logo), the artwork files and size limits, the regulatory and safety marking that must stay on the pack, the user manual and any warranty card in your name, the packaging marks, and an approved pr

Collect five groups of evidence before you contact the supplier: identification (serial number, model, ship date, order reference), the fault record (BMS alarms and fault codes with timestamps, cell voltage spread, temperatures, state of charge, cycle count), charging and use records (charger model

Under Incoterms 2020, risk moves to you earlier than most buyers expect. With EXW it passes once the goods are placed at your disposal at the seller’s premises. With FOB it passes when the goods are on board the vessel at the origin port. With CIF it passes at the same on-board point, even though th

Audit the process, not the showroom. Cover seven areas: incoming cells and components, pack assembly and BMS programming, in-process and final testing, traceability from cell lot to shipped serial number, calibration of test equipment, handling of nonconforming product, and shipping documents. For e

Regeneration is a likely cause. When the pack is full, there is little room to accept charge. Current from regenerative braking can push cell voltage or charge current past the BMS protection limits, and the BMS disconnects to protect the cells. Later in the day the pack has room, so the problem goe

Often it’s the state-of-charge estimate rather than the cells. Most BMS units count current in and out and only reset to an accurate 100% at a confirmed full charge. If the battery rarely reaches full, the estimate drifts, and the cells reach their low-voltage limit while the display still shows a m

Not necessarily. A healthy LiFePO4 pack loses capacity gradually. Redway’s 48V 100Ah OEM pack, for example, is quoted at a cycle life of 4000 cycles, so a noticeable drop after one season usually has another cause: cold weather, a charger that stops short, a state-of-charge meter that has drifte

Usually it’s the charging setup, not the battery. Common causes are a converter that isn’t charging in a lithium mode, voltage drop in thin or long cables, a monitor reading voltage rather than counting current (or a shunt in the wrong place), and a bank that hasn’t completed a full charge for a whi
