Lifepo4 100ah 200ah 300ah 400ah 12V Lithium ion Battery for Solar System/Motor Home/Boat/Golf Carts car battery (12V 400ah ×1pcs)

Product Information

At 3000 life cycles, it’s a very long-lasting battery. That means as much as 15-20 times longer lasting than a lead-acid battery. 3000 life cycles is very likely to be at 50% DoD – that means the battery should achieve 3000 cycles if you consistently discharge only to 50% each time and then recharge. Maintains power even when charge is low – when you reach a high level of discharge, well beyond 80%, this battery will keep producing consistent power, you won’t experience those annoying voltage drops you get with poorer quality batteries.

One of the major advantages of Lithium batteries is that they can cope with high discharge, even up to 90%. So you can certainly allow this battery to reach a high level of discharge. It’s the case for Lithium batteries, just as with any battery, that you’ll maximise the battery’s lifespan the less you let it get into high states of discharge. IP55 means it’s protected against an amount of dust that could interfere with normal operation but it’s not fully dust tight; and with complete protection against solid objects. And it’s protected against water splashing from any angle and against water jets projected by a nozzle (6.3mm) from any angle. IP65 means it’s fully dust tight.

Depth of Discharge refers to the % you can discharge your battery. When you reach that % you must you must recharge.

So discharge to around 90% you’re not seriously compromising the LiFePO4 battery’s life, it’s just not best practice. Extremely Fast RechargeThe best Lithium leisure battery’s in-built BMSs will automatically shut down the battery when discharge gets too high, normally approximately 95% discharge. When all’s said and done, there’s really a lot to like about Lithium leisure batteries for motorhomes, campervans and caravans. If you look at car batteries, (which are lead-acid), the reason so many people struggle to start their cars if it gets very cold in winter is that the cold temperature causes lead-acid batteries voltage to drop down too low. That means the battery voltage is too low, and it cannot deliver enough power to start the engine. Storage Temperature Range:Less Than 1 Week: -22°F~140°F (-30°C~60°C),Less Than 6 Months: -4°F~113°F (-20°C~45°C) Lithium batteries hold their voltage as they discharge much better than lead-acid batteries, especially in cold weather. That means that while you use your electronics appliances, a lead-acid battery voltage would drop down considerably faster than a Lithium battery would.
