Detailed design:

		Other
Plastic holder	1.We use customized plastic holder between each cells for better insulation, so when the operator install batteries, there will be no danger.	No holder between cell, insulation need to be concerned.
Top extension	2.There is an extension at the top of the bracket. When there is a shock or heavy drop or vibration, battery itself will not be the first to bear the brunt	Have a metal top extension in the first one, no top extension in the second
Unblocked explosion-proof valve	3.The explosion-proof valve is not blocked, the physical structure safety of the cell is ensured	Both has blocked explosion-proof valve, not meet the cell safety using requirements
BMS with cover	4.BMS is well protected by metal cover, prevent damage for shock	No cover on both BMS
Laser welding+Screws	5. We use laser welding around the srew to further strengthen the connection to completely eliminate the risk of screw falling. Laser welding also reduce the contact surface between the screw and the bus bar to enhance current capability. This laser welding can also reduce internal resistance and reduce power consumpution. The user can get more power.	First has untidy welding, big risk of damage cables, second only srews.
Orderly cable arrangement	6. Orderly cable arrangement can reduce poor connector contact, short circuit and open circuit between wires.	lack of standardization, cables go through basbar in the first, disorder cables in the second
