Trampa battery packs are the latest in innovative battery technology. These packs offer a variety of unique features that cannot be found elsewhere. The utilization of PCB button contacts & cell-level fusing allows you to safely assemble your own 12s7p battery in less than 45 minutes with no wiring, soldering, or spot welding. With an integrated cell management system & VESC app connectivity, you have up-to-date information about the status of your battery at all times. Maintenance work and upgrades are easy as unscrewing a few bolts and replacing cells, ensuring years of worry-free riding with your battery.

Basics:

Trampa Battery Packs don't use spot welding to interconnect the individual cells. The connection is made via a 25A fused contact designed and manufactured by Trampa.

Using this pack allows you to purchase cells locally and fit them into a 12S7P cell array. After closing the pack, you have an extremely safe and high-performance battery with an integrated management system. If a cell goes bad, you can easily swap it out.

Once your cells reach their end of life, you can simply install new cells onto the same PCB and recycle the old. This is in contrast to spot welded packs that can't be serviced and must be recycled once a cell goes bad. In this way, your PCB pack will retain perfectly healthy cells and save the environmental impact of throwing an entire battery away.

Wiring:

With the exception of one balance cable and the connectors from the PCB to your VESC setup, Trampa batteries require no wiring. This saves hours of time and makes maintenance and assembly much easier.

Battery Management System:

Trampa only uses the latest in onboard BMS technology. Utilizing the same chipset as Tesla battery packs, this pack features a self monitoring system of automotive grade. The system will consistently monitor pack temperature and humidity, and offers direct connectivity to the VESC app for your convenience. The BMS also features SWD, CAN-Bus, and USB connectivity to inform the VESCs of individual cell voltages, so that the voltage cutoff can be safely activated when riding. Firmware updates can be managed via VESC-Tool and the CAN interface. 

Safety:

Individual cell fusing will give you the confidence that each cell in the pack is secured against short circuiting. Any faulty cell will be decoupled within seconds to avoid damage or danger to the rest of the pack. There are 5 temperature sensors to keep you up to date with accurate temperature readings of your battery. A humidity sensor is also included to inform you if water enters the pack. In the event of a charging failure, each charge port is equipped with a Mosfet switch that allows the BMS to decouple the charger at any time. Cell failures can be easily addressed by unscrewing the lid of the pack and replacing unhealthy cells.

Flight Information:

Most airlines require battery packs to be smaller than 99wh to travel. In order to comply with this restriction, you can disassemble and safely store components of your pack before flight and reassemble upon arriving at the final destination. Please be sure to discuss with your airline before arrival at the airport to avoid missing any additional restrictions.

Trampas battery packs are the latest in innovative battery technology. These packs offer a high energy density (WH per Volume) and are therefore perfect to power our mountainboards or other applications.

So what makes these packs so special?

The Trampa Battery Pack Technology doesn't use spot welding to interconnect the individual cells. The connection is made via a special, 25A fused contact element, designed and manufactured by TRAMPA BOARDS LTD.

Using this pack allows you to purchase cells locally and fit them into a 12S7P cell array. After closing the pack, you have a perfect battery with a perfect battery management system. And if a cell goes bad one day, you can swap out individual p-groups in no time.

If your cells reach their end of life, you can simply buy new cells and recycle the old. So instead of buying a new and expensive pack, you will only need relatively cheap new cells. The initial investment might equal the investment of a pre-made pack, but as soon as it's time to replace the cells, the price drop in getting a second pack is dramatic. Spot welded pack can't be serviced and are pretty much useless the day one cell goes bad! Way too many good cells end in recycling these days, only because they sit next to a bad cell, permanently interconnected via a spot weld - we resolved this issue and offer an environmentally friendly solution, so that the same pack can stay healthy for a way longer period of time.

Wiring:

There is no wiring involved. Everything is PCB based, neat, tidy and clean.

BMS:

The BMS on this device is the latest in BMS technology. Using the same chipset that is used by the world's leading electric vehicle manufacturer TESLA, this pack features a self monitoring system of automotive grade. Beside that, the system monitors the pack temperature in several locations and allows placement of an additional temperature sensor that can be attached directly to a cell in the middle of the pack. A humidity sensor monitors the humidity inside the enclosure, so that water ingress can be spotted via App. Did I say App? Yes, the pack is connectable to the famous VESC-Tool App. You can not only monitor the pack, but also work on your pack and start and stop balancing, even if you're not charging at that time. The BMS also features CAN-Bus connection and VESC motor controllers can therefore know individual cell voltages, so that a low voltage cutoff can be executed in reference to the lowest cell voltage in the pack, preventing over-discharge of individual P-groups. The BMS features SWD, CAN and USB connectivity. FW updates can be managed via VESC-Tool and the CAN interface. CAN also allows you to couple individual packs to form a bigger battery array (in series, in parallel or both). The CAN Bus is therefore 600V isolated.

Safety:

- Individual cell fusing will give you the confidence that each cell in the pack is secured against short circuiting. A faulty cell would be decoupled within seconds and would therefore not cause any further danger.

- Temperature monitoring in up to 5 locations of the pack.

- Humidity sensor

- Self monitoring, automotive grade chipset.

- App connectivity lets you see what is going on with your pack. Are my cell all healthy and good?

- Charge port with Mosfet switch allows the BMS to decouple the charger at any time.

- Easy to service and extract unhealthy cells.

Pack capacity is roughly 1KWh:

Sony VTC 6: 3120mAh x 7 = 21840mAh = 969Wh

Samsung Q30: 3000mAh x 7 = 21000mAh = 932Wh

LG 18650 MJ1: 3500mAh x 7 =24500mAh = 1087Wh

Build time:

Roughly 45 minutes

M3 x 10mm TORX Countersunk Head Bolt Marine Grade Stainless Steel

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.

The head of this Bolt is COUNTERSUNK, meaning that when screwed into position it sits flush & neat with the surface its screwed into. Preventing bolts from standing proud eliminates the chance of anything getting "snagged or hung-up" should it get caught on something..
