ORRSOM Longboard Under board Battery Tray - Ready to fit

TRAMPA's ORRSOM Underboard Battery Tray is produced in long strips of up to nearly 2 meters in length. It is supplied to us as long lengths where we cut it down by hand to size to suit the customers requirements & we also send some of the long lengths to the water cutters where it is precision cut with water & the CNC machnine to our exact length & requirement to fit perfectly to the ORRSOM longboard Deck.

Measuring 26mm deep the tray is relatively shallow which arguably restricts its battery capacity & consequently its range, everybody knows TRAMPA is famous for good range & performance.... o

Originally developed to squeeze in to the Tray space 6× 10000mAh 2s Li-Po Cells,. This combination gave a amazing range of up to 25 kilometers (70kg rider) & a very punchy 12s performance when riding the STICKIES wheels (The ORRSOM Board was developed originally to be a Longboard using Longboard wheels where you do for sure get much better range performance) gave over 25km's of range when running on good surface at relatively constant high speed which was loads of performance, but we had problems with the supply of the batteries & the wiring together of the 6x 2s Li-Po cells was quite complicated, specially when it came to the charging, we just thought it was too much for the general public to deal with so we now suggest fitting a 12S 3P Lithium-Ion pack using the 18650 cells which gives pretty much the same range & almost the same punchy performance as the Li-Po Cells

Although the battery tray is quite shallow, being made from the same material as the deck it gives a very stealthy look & when you purchase the complete Watercut/CNC Battery Tray as a kit to fit to the deck, it fits llke a glove to the ORRSOM longboard deck! PLUS, the Structure

It was possible to House 6x 2s 10000mAH HRB High performance Cells to give you ORRSOM long range & amazing 12s power when using the STICKIES wheels!!

You can purchase the raw battery tray in lengths of 10 cm's, whereas if you had to the battery box pages you can purchase the complete awesome underfloor battery tray with all the fixing parts required...  The ORRSOM Underboard Battery Tray comes supplied with CNC Anodised End Bungs, Rubber Grommets silicone seals & strips of foam to be able to seal your deck off to be waterproof!

M4 x 25mm Dome Headed TORX Bolt - Marine Grade Stainless steel

TORX Screws are less likely to strip out when compared to a hex screw, because of the way the load is distributed and applied between the tool and the hardware. Because of this load distribution, the height of the head of the bolt can be reduced - making them nice & flush. 

Made from A4 Marine Grade Stainless Steel, all of the nuts, bolts & screws used in a TRAMPA board have proven to be up to the challenge of holding everything together. Using Marine Grade Stainless Steel also means these Bolts will never rust on you! They can cope with the harshest of weather conditions & will laugh in the face of sandy/salty beaches or muddy freeride tracks - which can turn other manufacturers’ nuts & bolts into corroded rusting wrecks!

Wherever possible, we dip all our bolts into BLUE THREAD LOCKING PASTE, to ensure an extra strong & secure fix between the nuts & bolts.

M4 8x8mm Nikel plated Flush fitting Threaded Insert Nut is Screwed into the ORRSOM longboard deck & used for fixing the Underboard Battery Tray to the Deck

This M4 8m x 8mm RAMPA Muffen or Insert nut will allow you to secure M4 Bolts to your deck without the need of using often unsightly or protruding nut on the other side leaving a neat clean smooth finish to your assembly....

We use these M4 RAMPA Nuts to secure the UNDERBOARD Battery Tray to the underside of all of the Electric ORRSOM Boards...

To make the hole to accept the fitting the nut, you will need to measure accurately so first make a pilot hole using a 2/3mm drill bit. Then specifically using a 5mm Steel drill bit, carefully drill the larger sized hole remembering to drill at 90º to the surface. If you do not Drill 90º to the surface your RAMPA Nuts will not fit flush...

Once you have made the 5mm holes, use a 4mm Allen Key to screw the RAMPA nut into the deck. Be careful when screwing in, you need to add a little bit of force to make it bite into the surrounding material, but not too much force as you do not wish to push through anything.... Turning the M4 Allen Key may be tough as when screwing the nut into the deck as it will literally cutting a thread into the surrounding material of the deck as you do...  It may help secure the RAMPA nuts even better if you add a tiny squirt of Glue as you tighten up the last few turns...
