After building my first board see [HT Build One](https://foil.zone/t/hts-first-build-in-austria/9648/50) I’ve decided to build a smaller compact board with a taller mast. I have used all my experience from the first build to design and build the second board. I couldn’t find a suitable blank so I bought my own styrofoam block and shaped the board myself. I will include many pictures and videos to help any would be builders.

Built my 14s12p battery using **Samsung INR21700-40T (40T3) 4000mAh - 35A**. I ordered my cells and nickel strips from [NKON.NL Samsung 21700](https://www.nkon.nl/en/samsung-inr21700-40t-4000mah-35a-2022.html). Using the [K-Weld](https://www.keenlab.de/index.php/product/kweld-complete-kit/) I was able to spot weld the strips to the cells. The silicon coated wire is 6awg or 13mm2. Insulation paper, Koptan tape, bullet connectors, 7p balancing wires, and the waterproof connectors are all ordered from Amazon or Aliexpress. Hobby chargerand balancer is a [ISDT Q8](https://www.amazon.de/HBITT-ISDT-Q8-Q6-Lite-White/dp/B081YZLMV4?ref_=ast_sto_dp&th=1)

Board is finished fairing, sanding, and Painting.
I bought the 2k Acryl paint from [Lackmix.de](https://www.lackmix.de/Start) in germany.
All the fiberglass/carbon fiber and epoxy is from [HP Textiles](https://shop.hp-textiles.com/shop/en/).
The gasket seal for the top of the board is [Multi-hole I/E/D type Silicone Rubber Weather Strip For Door Window Sound Reduction Seal Strips Self-adhesive Tape Insulation 14X12mm gray, 6M](https://www.aliexpress.com/item/1005002663293012.html?spm=a2g0o.order_list.order_list_main.49.34f21802F0fmMM)
The hinges for the hatch are from Amazon [Stainless Steel Hinge](https://www.amazon.de/dp/B08NK3XYWH?ref=ppx_yo2ov_dt_b_fed_asin_title)
The waterproof hatch I bought on Amazon [Flush Cam Latch made by OSCULATI](https://www.amazon.de/dp/B01DPVQI6A?ref=ppx_yo2ov_dt_b_fed_asin_title). I did a lot of research on these latches and I am very happy with them.
The EVA mat on the top of the board is very similar to this one [Camouflage Eva Boat Decking](https://www.hjdeck.com/products/marine-camo-boat-flooring-eva-foam-boat-decking-non-slip-boat-mat-self-adhesive-boat-carpet-mat-rolls-for-kayak-deck-boat-yacht-flooring-motorboat-94x45-35-23-16?variant=47988805304595)
