ABYSS BATTERY for Every Water Pursuit

Curious about how our lithium phosphate batteries are made? ABYSS Batteries are built with select marine-grade components and a unique construction that defines a new standard of reliable performance.


Every Abyss battery features an Internal battery management system (BMS) that stabilizes cell voltage, prevents overcharging, over discharging, reverse polarity, and short circuits.

We use the industry's safest LiFePO ₄ chemistry and utilize both large-format prismatic cells and cylindrical cells for more efficient and reliable battery connections.

 

Using large format cells simplifies pack formation and system integration. Each bus bar connection to a cell terminal is secured using 4 screws, providing a much more robust connection and reduced contact resistance.

 

Our cell holder design construction is advantageous because it eliminates failure points, prevents short circuit events from happening, and improves the overall heat dissipation of the battery pack while charging and discharging.

 

Our bus bars are made of silver-plated copper to achieve maximum conductivity and have a high resistance to corrosion for maximum performance and durability.

With phosphate-based chemistry and a safety valve design, our lithium-ion battery cells demonstrate the highest safety performance in the industry. The safety valves can pop open under abusive conditions, quickly release internal cell pressure, and thus prevent cells from catching fire. ㅤㅤ

ㅤ

Abyss battery format cells are housed in an explosion-proof aluminum casing. Tests have been conducted to confirm cells do not catch fire or explode in various abusive conditions, such as nail penetration, short-circuiting, over-charging, over-discharging, over-temperature, crushing, and dropping. We manufacture our battery packs with the best Grade-A cells that money can buy, certified with UL1642, and do not cut corners in our assembly process. 

ABYSS batteries are different from those of other manufacturers. Our lithium batteries for boats are manufactured with the highest-grade cells, proprietary peak surge stability, and a transient voltage BMS (battery management system). Our BMS operates seamlessly with any application and automatically manages all of the module's system parameters in real time. The module's inherent safety, extended cell life, and zero maintenance offer end users a more reliable battery alternative by performing with more than twice the run-time and less than half the weight of similarly sized SLA, Gel, and AGM batteries.

Certifications and compliance

We only use Grade-A cells listed with UL standards entities

QUALITY AND ENVIRONMENTAL MANAGEMENT SYSTEMS (ISO Certified) ISO 9001:2008 Quality Management System ISO 14001:2004 Environmental Management System IEC/UL 62133IEC62133 certifications and additional laboratory services are available as required 
by our OEM clients.

UN/DOT 38.3: Lithium
Battery Transportation

ㅤ

All Abyss Battery®, Inc. Lithium Batteries are required to pass section 38.3 of the UN Manual of Tests and Criteria, to ensure the safety of using products for our end users and for shipping purposes. We are proud of our investment to ensure our products have been UN38.3 certified.


T1 – Altitude Simulation: This is low pressure testing that simulates unpressurized airplane space (cargo area) at 15,000 meter altitude. After storing batteries at 11.6kPa for >6 hours, these criteria shall be met: no mass loss, leaking, venting, disassembly, rupture or fire, and voltage within 10% of pre-test voltage.


T2 – Thermal Test: This test covers changes in temperature extremes from -40°C to +75°C. Batteries are stored for 6 hours at -40°C (12 hours for large cells/batteries), then 6 hours at +75°C (12 hours for large cells/batteries), for a total of 10 cycles. Testing may be performed in a single chamber or thermal shock chamber, but less than 30-minute transitions shall be used.

ㅤ

T3 – Vibration: This test simulates vibration during transportation. Test is a Sine Sweep: 7Hz – 200Hz – 7Hz in 15 Minutes; 12 Sweeps (3 hours); 3 mutually perpendicular axes.

ㅤ

T4 – Shock: This test also simulates vibration during transportation. Test is a Half-Sine pulse: 150G/6ms for small cells/batteries; 50G/11ms for large cells/batteries; 3 pulses per direction; 6 directions (+/-z, +/-x, +/-y). Same pass criteria as T1.

ㅤ

T5 – External Short Circuit: This test simulates an external short to the terminals of the cell or battery. At temperature of +55°C, apply short circuit (<0.1ohm) across terminals. Maintain at least an hour after sample temperature returns to +55 +/-2°C. Pass criteria are: Case temperature does not exceed +170°C and no disassembly, rupture, or fire within 6 hours of test. Fuse, current limiting circuit, and venting mechanism activation are allowable.

ㅤ

T6 – Impact: This test is only applicable to primary and secondary cells. For cylindrical cells >20mm diameter, it simulates impact to case of cell. For cylindrical cells <20mm diameter and all other cell constructions, it simulates crushing of a cell. Pass criteria for any type is: Case temperature does not exceed +170°C & no disassembly or fire within 6 hours of test.

ㅤ

T7 – Overcharge: This test is for secondary or rechargeable batteries only. It simulates an overcharge condition on a rechargeable battery: 2x the manufacturer’s recommended charge current for 24 hours. Then battery shall be monitored for 7 days for fire or disassembly.

ㅤ

T8 – Forced Discharge: This testing simulates a forced discharge condition for primary and secondary cells only.

These Abyss Lithium batteries are Legit! I know a lot of anglers that have been on the Lithium train for a while now, but it took me a while to get on board. I am now a believer! My Abyss 36V lithium battery had my Minn Kota 112 Terrova running stronger and smoother than it ever has, and my trolling motor is only a year old. Ran it hard for 9 hours in 15-20 mph winds and never lost ANY power...
