2 Pack 12V 100AH Lithium Ion Deep Cycle Battery Group 31 Battery for Trolling Motor,RV

【15000 Deep Cycle Marine Battery】12V 100Ah LifePO4 Lithium Battery with stable performance, 100Ah high capacity, Max.1280W.Our 100ah lithium battery are suitable for trolling motors, and can be recycled from 4000+ cycles, with a service life of up to 10 years

【100A BMS Protection】The upgraded 100A BMS features protection against overcharge, over-discharge, over-current, over-voltage, overload, and short-circuit, making it easy to respond to a variety of environments and situations anytime, anywhere. 12V 100Ah lithium batteries are ideal for solar homes, RV, camping, trolling motors, and off-grid applications

【Replacement Lead-Acid Batteries】The 12.8V 100Ah LifePO4 battery consists of li iron phosphate batteries for higher energy density and unmatched power. 100Ah lithium batteries are up to 24 pounds lighter, 50% lighter than traditional lead-acid batteries, and up to 35% smaller for the same capacity, making them much easier to move around with or carry

【Expandable Capacity】The 12V 100Ah lifepo4 deep cycle battery supports series and parallel connection for more power, allowing up to four batteries to be linked. You can freely DIY solar battery system to power your home without worrying about power outages caused by extreme weather

【Warm Tip】For transportation safety, our batteries are only 60%-70% charged at the factory, please charge the batteries before you receive them, we recommend using a 12.8V (14.6V) lifepo4 charger. Please note that our batteries should never be used for car ignition

(4 Pack) 12V 100Ah lifepo4 battery connection Tips
Voltage Balancing Before Connection:
To connect in series or in parallel, Necessary to reduce the voltage difference between batteries and let the battery system perform the best, batteries should meet below conditions:
Firstly, the same battery capacity (100Ah)
Secondly, from same brand (as lithium battery from different brands has their special BMS) and purchased in Latest time (recommend within one month)
Thirdly, fully charge the batteries separately (voltage at rest:> 13.4V) before connect in series or/and in parallel
Fourthly, Connect the batteries one by one in parallel, and leave them together for 12-24hrs.

Note:
1.It is recommended to use 1WG connecting wire, with a minimum requirement of 2WG wire
2.Battery Equalizer 48V Reverse polarity protection, low voltage disconnect, keep the battery in series or parallel for a long time, so as to automatically keep the battery in a balanced state, keep the battery in a healthy state, prolong the life of the battery, Recommended to buy!

IF The battery is not charging and there are several ways to solve the problem:
1. Use an equal voltage battery, positive to positive and negative to negative, this will activate the battery
2. Use an adjustable power supply to power up the battery, positive to positive and negative to negative, this will activate the battery
3. Remove all connected batteries and try charging with a 12V (14.6V) lifepo4 charger for 5 minutes to activate the battery
