D0NGHOT 4 Pack 12V 100Ah LiFePO4 Lithium Ion Battery 48V Lithium Battery for Golf Cart,RV,Solar

【Lithium Iron Battery】Lithium ion batteries last 8 to 10 times longer than regular lead-acid batteries. They also have double the capacity and weigh 30% less. Unlike lead-acid batteries, lithium batteries don't lose capacity when not in use.It is an excellent choice for replacing traditional lead-acid batteries!

【15000 Times Deep Cycle & Long Lifespan】Our Lithium Iron Phosphate(LiFePO4) battery is manufactured with automotive grade lithium iron phosphate cells, which offers higher energy density, more stable performance and greater power. Unlike lead-acid batteries that typically last for only 300-400 cycles, our lithium-iron batteries can be recycled up to 4000 time cycles(100% DOD), 15000 time cycles(60% DOD), providing up to 10 years of lifespan.

【100A BMS & Grade-A Cells】The built-in Battery Management System (100A BMS) monitors the lithium battery status at all times,including voltage,charge and discharge current,temperature,etc.,to prevent overcharge,over-discharge, overload, and overheating, low temperature,short circuit conditions occur.Makes lithium iron phosphate batteries safer to use and charge, and can directly replace lead-acid batteries in deep cycle applications such as trolling motors,marine,solar and RVs.

【4 Pack 12V 100Ah Series to 48V 100AH】Our deep cycle lithium ion battery can be connected in series or in parallel with the same type batteries. Max connection in series: Up to 4 identical batteries for up to 48V connecting in series. Connection in parallels: it can connect multiple batteries, suggest no more than 4 pcs in parallel. Under the premise that each 12V 100Ah lithium battery of the same brand and model is fully charged.
Warm reminder: Do not use this Lifepo4 battery as a starting battery. It is more suitable for use as an energy storage battery.

IF The 12v 100ah lithium iron 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 activate them using a 12V (14.6V) lifepo4 battery charger with battery activation.
