Free shipping: shipment from EU stock--Poland warehouse.
DDP: door to door, tax free, shipping time within a week.
Customer what need to do: buy cells + DIY kits= assemble by themselves.
The Kits are proper for :
EVE/CATL/CALB/Hithium/Gotion and others brand 280ah/302ah/304ah/310ah/314ah/320ah cells The battery cells are EVE model, HSEV top level" Matched can tested.
We recommend two combinations for you：
With 4pcs EVE 314Ah：Strong performance and high adaptability
With 4pcs CATL314Ah：Higher cost performance
