FAQs

Fully charge the batteries prior to long-term storage. Perform a supplementary top-up charge once every month during storage. If the equipment is fitted with a master disconnect switch, turn it off to cut no-load circuit and minimize standby self-discharge loss.

They are not interchangeable. Flooded batteries require a higher charging voltage. If an original flooded-battery charger is used for AGM batteries, the excessive charging voltage will accelerate electrolyte dehydration and cause AGM cell bulging and premature failure. Conversely, when flooded batteries replace original AGM units, the AGM-specific charger delivers insufficient voltage to fully charge flooded batteries, leading to chronic undercharging and drastically shortened service life over time.

Several issues can cause this behaviour. A large voltage difference between cells may trigger BMS protection and substantially reduce usable capacity. The BMS itself may also have a fault affecting cell balancing, charging or discharge control.

A weakened cell with high internal resistance can limit the performance of the entire battery pack. An incompatible, aging or faulty charger may also prevent the battery from charging correctly. If the problem persists, stop using the battery and have the pack, BMS and charger inspected by a qualified technician. Do not bypass the BMS or continue operating a battery that overheats, swells or shows visible damage.

LiFePO₄ is widely used because it offers strong thermal stability, long cycle life and competitive lifecycle value. Its lower risk of thermal runaway makes it well suited to low-speed vehicles operating across uneven roads, frequent cycling and varied working environments.

Compared with ternary lithium chemistries such as NMC, LiFePO₄ generally offers lower material costs and greater cycle endurance. Although ternary lithium can provide higher energy density and stronger low-temperature performance, these advantages are often less important in short-distance, low-speed applications where safety, durability and cost are the main priorities.

Always use a charger, wiring harness and connectors that match the battery specifications. Frequent high-current operation—such as prolonged climbing under maximum load or repeated hard acceleration—can accelerate cell aging.

Store the battery in a cool, dry environment away from direct sunlight, rain and extreme temperatures. For extended storage, maintain approximately 50% state of charge, avoid leaving the battery below 20%, and check and recharge it at least every three months or according to the manufacturer's instructions. Charging conditions, discharge depth, operating temperature, load and storage state of charge can all affect service life.

In many applications, a lithium battery with the same nominal voltage can replace an existing lead-acid battery, but compatibility must be confirmed first. Check the battery dimensions, mounting arrangement, terminal polarity, wiring, controller requirements, discharge current and communication interface where applicable.

A compatible lithium battery charger must also be used, as lead-acid and lithium batteries require different charging profiles. Depending on the battery capacity, vehicle efficiency, payload and operating conditions, a suitable conversion may extend driving range while reducing weight, routine maintenance and the risk of acid leakage.
