Chins 12.8V/400Ah LiFePO4 Deep Cycle Battery

Chin's has its own factory, are mainly engaged in LiFePO4 and lithium-ion battery business, which is very suitable for RV, Caravan, Solar, Marine, Home Storage and Off-Grid.

Deep Cycle Battery

Our LiFePO4 battery provides 2000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times that of standard lead-acid batteries. The weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged.

Lithium Iron Technology

CHINS deep cycle lithium-ion battery has higher energy density, more stable performance and greater power. LiFepo4 battery will not burn when overcharged, overdischarged, overcurrent or short circuit, and can withstand high temperatures without decomposition. It can support fast charging and solar panel charging. Our LiFepo4 batteryis a green battery, it does not contain any heavy metals and rare metals and is more environmentally friendly.

Built-In BMS & Convenience & Maintenance Free

Our LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high temp cut off prevents charging over 122 °F (50 °C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults. This product is your best choice for outdoor camping power and indoor easy installation.

Capacity Expansion

Our Lifepo4 batteries can be connected in parallels 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, suggest 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 400Ah) and higher voltage (24V, 48V). Other installation methods: 3S2P, 4S2P, 4S3P, etc.

Widely Used

Our lithium iron phosphate batteries can be used in the following areas: Home energy storage system, UPS backup, lighting, digital/CCTV cameras, portable TV, e-Robot, electric vehicles, DIY loud speaker, 12V router, air pump, fish finder, golf car, trolling motor, motorhome/RV & camper, Houseboat, Travel Trailer, Dump Trailer and more. When the batteries are used in parallel or series, the battery voltage and capacity must be the same, and purchased in near time(within 6 month).

Seem to be good batteries

These batteries arrived in good condition and are ready to use. The quality appears good and the charge seems to last well. I have only used them for 6 months so cannot vouch for the length of life. I would buy them again.
