LANPWR 12V 300Ah LiFePO4 Lithium Battery Pack Backup Power 3840Wh Energy 4000+ Deep Cycles Built-in 200A BMS for RV Electric Boat Solar System ( Item#: FX-SW-LFP12-300LP-EU-EU )

10 Years Lifetime & 1/3 Lightweight
LANPWR LiFePO4 battery provides 4000+ cycles, which is more than 10 times Lead Acid with 200-500 cycles, helping to minimize replacement cost and reduce the total cost of ownership. weighs only 1/3 the weight of lead-acid batteries, which makes it an easy choice for RVs, Marine, and Off-Grid Applications when mounting or mobility is in consideration.

Automotive Grade Lithium Battery & Eco-friendly
12V 300Ah LANPWR lithium iron phosphate batteries have exceptional quality since they are manufactured by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power. LiFePO4 batteries can be recycled and do not produce elements that are harmful to the environment, but lead-acid batteries pollute the environment.

Capacity Expansion
LANPWR LiFePO4 battery can be connected in parallel and in series for larger capacity and voltage. Max connection in series: Up to 4 identical batteries for up to 48V connecting in series. Connection in parallels: it can connect multiple batteries, suggesting no more than 4 pcs in parallel. Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 1200Ah) and higher voltage (24V, 36V, 48V). When the batteries are used in parallel or series, the battery voltage and capacity must be the same and purchased in near time (within 3 months).

Built-in 200A BMS
LANPWR LiFePO4 battery has built-in 200A BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuits with an excellent self-discharge rate. Built-in high-temp cut-off prevents charging over 122°F(50°C). Without memory effect, no matter what state the battery is in, it can be used as soon as it is charged. LANPWR LiFePO4 battery is IP65 level. Brand: LANPWR
