About 12v 100Ah LiFePo4 Lithium trolling motor battery

12 volt 100ah lithium battery apply with high-quality lithium iron phosphate batteries, the battery system come with Built in BMS protection. Battery casing with IP67 waterproof.

Optimized structure.
The battery system can effectively charge and discharge the battery pack for real-time monitoring and protection,The protection temperature for charging and discharging is set independently,To prevent any battery in the battery pack overcharge, over discharge caused by damage, And can control the battery charge, discharge current,Ensure that the battery pack and applications are not damaged;To ensure that in the event of a short circuit failure when the output off and automatic balance of the application of the battery pack at any time in the best condition.

Safety and economical

12v trolling motor battery does not explode or catch fire like lithium cobalt (found in cell phones and laptops etc). It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons it’s safe for household use.

Excellent discharge characteristics

lifepo4 prismatic battery With low internal resistance and high, flat voltage characteristics during strong current discharge, which ensures a wider application field. Like trolling motor, Lithium RV battery packs. or any other backup power systems.

Long cycle life

Prismatic lifepo4 battery cells Provide long storage life with few limiting conditions. It offers problem-free charge after long storage, permitting to use in a wide range of applications.

Safty Test:

  • Over-charge test
  • Over-discharge test
  • Short-circuit test

Battery pack maintenance rules

a) Battery pack at the factory charge of 30% -80%

b) Each time the battery pack is used for one month, the following checks should be made. If the fault is found, it should be excluded immediately.Found that the fault should be immediately excluded。

(1)All kinds of fasteners bolts, nuts are loose.

(2)Whether a variety of harness with no abrasions, with or without metal wire exposed。

c) When the battery pack is not used for a long time, the battery pack is fully charged and the output circuit breaker is turned off.And then turn off the output circuit breaker.It is recommended to make a charge every March or so.
