I am in the process of building my first travel battery, I have choosen the BA45D and i am going to build 3S2P (97.2 Wh) packs, since i can then take with me up to 20 packs.
Which will be used to put a 15S2P 486 Wh pack together. I am also planing to build a BMS board which i will use to put the packs toghether with a JBD BMS.
I have seen in the forum a few people have done this before, but i havent read many experiencies taveling with DIY batteries. Do you have to provide any info when crossing the airport control or just having properly labeled, properly enclosed batteries is enough?
I am travelling in Europe…
