I am designing a new power system for yacht with up to 6 NG LFP batteries 200Ah. To connect to batteries I am hesitating between Lynx Distributor or Lynx ClassT Power In. THe later looks more expensive, but I haven’t been able to pin point the clear advantage of it. Has anyone some experience on that ?
Mostly it is the difference in fuse being used. Class T is capable of interupting a higher current and therefore safer.
The NG batteries have no BMS inside to limit current, the cells are connected directly yo the terminals by heavy copper strips. They have very low resistance and high fault current of up to 10,000A or more. Mega fuses are only suitable up to 2,000 or 3,000A fault current. You should using class T or another high AIC (ampere interrupt current = fault current). Some people have been using the Lynx Distributer with Adler EF3 fuses, cheaper than Class T and high AIC. Do a search for Adler or EF3 on this forum.
btw I used Class T on my 300Ah NG batteries.
For this installation, I need to accommodate 6 200Ah NG batteries. Using ClassT, I will need 3 of them. That is a lot. Ok, let me look for Adler or EF3 for Distributor
