Three voltage classes — 24V, 36V and 48V — with customisable capacity, 200A continuous discharge and the charge-cycle economics that move fleets off lead-acid.
Forklift batteries are bought on cost per shift. The Improve range covers the three standard truck voltages — IMP-FK-24-200 at 25.6V 200Ah, IMP-FK36-600 at 38.4V 600Ah and IMP-FK48-200 at 51.2V 200Ah — with capacity customisable on every model, because truck battery compartments differ by maker and era and the battery has to fit the iron, not the other way round.
All three carry a 6,000-cycle rating at 80% depth of discharge and 200A maximum continuous discharge, charge over CAN with 4G telemetry as an option, and sit in IP54 enclosures. The operating case for LiFePO4 in materials handling is opportunity charging: top up during breaks instead of swapping packs and watering cells, and let one battery cover multi-shift work that lead-acid handles with two or three packs and a battery room.
The forklift line does not stand alone in the industrial range. The same platform discipline produces the smart forklift chargers (IMP-ADY series, matched to these packs), the floor sweeper battery (IMP-FCM-48-200) for cleaning fleets, and the UTV batteries — one manufacturer for the whole motive-power shelf, documented in one format.

Figures are the manufacturer's published data for this range. The written quote states the exact configuration of your build.
Published capacities are reference builds; capacity and fit are customisable per truck model and compartment.
LiFePO4 accepts charge during breaks without the memory and watering regime of lead-acid — one pack can cover multi-shift rosters.
CAN comes standard in the communication set; 4G is a published option for fleet state-of-charge visibility.
The IMP-ADY smart forklift chargers are specified alongside these packs, including CAN charging protocol options.
Converting a forklift fleet is a specification exercise: truck models, shift patterns, charger placement and opportunity-charge windows. Bring the fleet list to the enquiry — makes, voltages, compartment dimensions and shifts — and the quote returns a per-truck battery and charger specification with the capacity customisation stated model by model. The lead-acid replacement page works through the operating-cost comparison that usually starts the conversation.
Minimum order quantities and lead times depend on the product type and the degree of customisation: standard products can start from smaller batches, while custom housings, labelling and packaging are assessed per project. Samples can be arranged, with sample and freight costs confirmed against the requirement. Every enquiry is answered with a written specification and quote stating the model, configuration and terms - nothing about an order here is left to chat messages.
Improve Battery runs OEM/ODM alongside its standard range, and ships with the export documentation each model carries (CE, RoHS, FCC, MSDS, UN38.3 types as listed per datasheet; certificates available upon request). State the model, voltage, quantity and destination in the enquiry form and the sales team in Shenzhen will reply with the full specification.
Capacity is customisable and the reference builds share a 548 × 410 × 390mm case family. Send the truck make, model and compartment dimensions; the quote confirms the build.
Yes — LiFePO4 packs need matched charging. The IMP-ADY smart charger range is in this catalogue and is specified with the batteries in one quote.
It reports pack state — charge level and operating data — to fleet systems over the mobile network. It is an option at order level, confirmed in the written specification.
Model, voltage, quantity and destination - that is all a real quote needs.
