Frequently Asked Questions

What is the main difference between 48V and 52V battery packs?

52V batteries have a higher full charge voltage (58.8V vs. 54.6V), providing steady power output and reduced motor voltage sag under low battery levels.

How do I choose between 2600mAh, 3200mAh, and 3500mAh cells?

Higher cell capacities increase total battery energy (Wh). Selecting 3200mAh or 3500mAh cells allows up to 20Ah capacity without changing case dimensions.

How does the built-in BMS ensure safety during high discharge?

The BMS continuously monitors current and thermal levels, cutting off power in microseconds if thresholds are exceeded to prevent thermal breakdown.

What is the lead time for a custom batch of 10 sets?

Once configuration details are confirmed, production and testing take 7-10 working days before dangerous goods packaging and shipping.

How are overseas B2B shipments handled?

Backed by UN38.3 and MSDS reports, we deliver via licensed DG forwarders with sea, air, and DDP shipping options.
