Sample Workshop

We will conduct small-scale sample testing before mass production to verify product reliability, including thermal runaway, charge and discharge, waterproofing, over-discharge, etc., and use data to verify the performance of the battery pack.
Automatic Welding Machine

Laser Welding

We will use laser welding machines to produce standard modules. This method can greatly increase the welding strength, avoid false welding and possible looseness in the future, and also improve production efficiency.
12V 100Ah series testing

SOC Proofreading

In order to avoid excessive discharge of battery packs caused by long-distance transportation, we will conduct unified SOC testing before shipment and recharge battery packs below 55% to greatly extend the safe storage time of battery packs.
