FAQ & safety
Common questions
We offer Li-ion (NCM / NCA), LiFePO4 and LTO cells, chosen to match your project needs.
Yes. We provide structural design so the pack fits your housing, connector and mounting points.
Overcharge, over-discharge, overcurrent, short-circuit and temperature protection, SOC / SOH display and communication protocols such as CAN and RS485.
Yes. Charging rates from 0.5C to 2C are possible, depending on the cell specification.
Typically 12–36 months, depending on the project agreement.
Keep them at 50–60% state of charge in a dry, ventilated place between −10 °C and 35 °C.
Safe handling
Heat and damage
Never heat, disassemble or modify the battery, or dispose of it in a fire. Do not pierce, hit, step on or drop it.
