Frequently Asked Questions

Must the cells be balanced before assembly?
Yes, DIY battery packs must have balanced cells (same voltage) before assembly. We ensure individual cell quality before shipment, and we recommend testing within 15 days of arrival.
What if the batteries are damaged during shipping?
Please contact us immediately with photos or videos. If the battery is unusable or lost, we will communicate regarding resending, replacement, or refunding the product cost.
Do you test each battery before shipping?
Yes. Capacity tests have a <2% error margin. Voltage deviation is kept below 0.01V and Internal Resistance deviation less than 0.05mΩ.
Are busbars and bolts included?
Yes, all cells come with free bus bars and bolts/studs. Typically, 1 busbar and 2 bolts per battery.
What situations are not covered by returns?
Damage caused by improper assembly (wrong BMS wiring), charger failure, battery bulge due to overcharging without protection, or welding/wear on electrodes cannot be returned.
