Cycle Life & Longevity
The battery is rated for 4,000+ cycles under standard test conditions, where one full charge and one full discharge count as a cycle. In real operations, equipment is rarely drained to 0% before recharging. Most users recharge at around 30–50% remaining, which puts less stress on the cells and results in a longer actual lifespan than the rated figure.
How long it lasts depends on how often you charge.
- One charge per day: over 10 years of dependable use.
- Multiple charges per day (3-shift warehouses): cycle consumption increases, but capacity fades gradually and the battery delivers stable performance throughout its life.
Compared to conventional lead-acid batteries with only 1,200–1,500 cycles and higher sensitivity to charging habits, this lithium solution gives you longer service life, lower replacement costs, and more predictable performance.
Battery Management System (BMS)
The BMS is integrated inside the battery pack and continuously monitors voltage, current, and temperature while managing communication and protection functions. It tracks the voltage of all 12 cell series, identifying any imbalance and performing cell balancing during charging. This helps slow down long-term cell divergence and supports a longer service life.
Protection Functions
The BMS provides multiple layers of protection to keep your battery and equipment safe. Key protections include:
Overcharge Protection
Automatically cuts off charging when voltage exceeds safe limits, preventing cell damage
Over-discharge Protection
Cuts off output when battery depletes to prevent deep discharge damage
Overcurrent Protection
Cuts off when current exceeds safe thresholds during operation
Temperature Protection
Limits current or cuts off when temperature exceeds safe operating range
Short Circuit Protection
Millisecond response time to cut off power in short circuit events
Cell Balancing
Evens out charge across all 12 series during charging to extend battery life
Communication Interfaces
Two communication ports, RS485 and CAN. RS485 connects to upper computer, reads voltage, current, temperature, state of charge, fault codes and such. CAN is the protocol used on vehicles, interfaces with the vehicle controller, data exchange. Some fleet management systems need to connect to battery data, also goes through these two ports.
A detachable LED display is mounted externally for quick, at-a-glance status checks.
Charging Specifications
Charging must be done with a lithium-specific charger. Lead-acid charging curves are different and can cause issues such as incomplete charging, BMS protection triggers, or long-term cell damage. When replacing the battery, make sure to use a charger that supports lithium mode or replace the charger together.
The battery supports up to 250A charging current. To fully utilize this capability, the charger output power should match or exceed the approximate requirement of 43.8V × 250A ≈ 11 kW. Lower-power chargers can still charge the battery, but the process will take longer.
Charging is allowed only within this temperature range. Extremely cold winter environments or hot summer exposure can restrict charging. When the BMS detects temperatures outside the safe range, it will limit charging current or block charging entirely. In cold warehouses, bringing the truck to a warmer indoor area before charging is recommended.
The battery uses a REMA connector, widely adopted by European forklift brands such as Linde, Jungheinrich, and Still, and increasingly used by domestic manufacturers as well. This ensures compatibility and easy integration with most charging setups.

The battery supports a continuous discharge current of 250A. Hydraulic pumps and drive motors on reach trucks may occasionally draw higher peak currents, but these short bursts are handled safely by the BMS. For heavy-duty, long-term high-current applications, check that the battery meets the specific demands. Under normal operation, the battery performs reliably without issue.
When the battery voltage drops to 33V, the BMS automatically cuts off output to protect the cells. Operators may notice the truck losing power before the display shows empty-this is normal and indicates it is time to recharge.
Lithium batteries operate safely over a wide temperature range. In cold storage (-10°C to -20°C), capacity and power may temporarily decrease due to higher internal resistance, but the battery is not damaged and returns to normal at standard temperatures. This superior low-temperature performance is a key advantage over lead-acid batteries, whose output drops significantly in cold conditions.
Equipped with a high-current Anderson connector, widely used in North America and domestic equipment, ensuring reliable, secure connections for high-power discharge.
Storage Guidelines
Self-discharge less than 3% per month. Stored without use, charge slowly decreases, but very slowly. Lead-acid stored for a month can lose over ten percent, lithium much less.
For long-term storage, keep charge level between 40% to 60%, temperature 10℃ to 45℃, dry and cool place. Full charge storage is bad, empty storage is also bad. Check charge level every month or two, top it up.

Installation Matters
Measure battery compartment dimensions first. Length, width, height all need to match, also need to leave operating space for connectors. Some truck compartments are just right, battery goes in but connectors have no place to plug, have to take it out again, troublesome.
Fixing methods vary by truck. Pressure plates, bolts, clips, all kinds. A 910 kilogram object, when the truck runs, brakes, turns, goes over bumps, inertial force is significant. If not fixed securely it will shake, shaking and shaking the bolts loosen, poor contact, a string of problems follows.
Insert connectors in place. Both REMA and Anderson are plug-in type, push in and listen for the locking sound. Contact surfaces need to be clean, if there's rust or oxidation layer deal with it first. Check periodically, see if connector areas are heating up or discoloring.

Daily Inspection
Daily inspection is simple and takes minimal time:
Check the display daily, see if there are fault lights
When charging pay attention, see if sound and temperature are normal
Check shell exterior for impacts, bulging, leakage
Check if connectors are loose
No need to add water, no need to measure specific gravity, no need to do equalization charging
Switching from Lead-Acid
If you're used to lead-acid batteries, here's what you need to know: lithium batteries are maintenance-free, fast-charging, and safer, but have a higher upfront cost. Over time, their longer lifespan, efficiency, and lower operational costs make them very cost-effective in most applications.

| Cycle Life | 4000+ cycles | 300-500 cycles |
| Charging Flexibility | Charge anytime, disconnect anytime | Need full charge and full discharge |
| Charging Time | 2-3 hours for most capacity | 7-8 hours minimum |
| Maintenance | No water needed | Add water weekly/bi-weekly |

| Cold Performance | Much better | Capacity drops severely |
| Initial Cost | Higher | Lower |
| Total Cost of Ownership | Often cost-effective | Hidden costs add up |
