Before using the battery for the first time, please activate the battery with a charge/discharge current greater than 1A and measure the terminal voltage to validate. As we give information, tips and advice on car batteries and accessories, naturally our content may contain affiliate links, from which we earn, but there’s no extra cost to you. If you often charge at this too-low voltage, it won’t get a full charge, and it will start to treat that lowered level of charge as it’s full charge. The Beyond Batteries Lithium battery is really solid in all respects, with good BMS quality and Lithium cells quality as well. Since 2015, we've sold and installed thousands of lithium batteries and have learned a lot about them in the process.That said, if you really want to maximise lifespan, we’d recommend not discharging completely (to 100%) too often, taking it to 80-90% can mean it’ll last an extra few years. One of the major advantages of Lithium batteries is that they can cope with high discharge, even up to 90%. In our testing, it also maintained power very well throughout usage, without dips or losses of power. Today the experts on off grid power will be checking out the brave, new(ish) world of LiFePO4 batteries and doing a Kepworth Lithium battery review. Because sulfation is a natural process and is impossible to completely eliminate, no matter what you do (though you can take steps to minimise sulfation and thus maximise the length of your battery life).

Faster to charge – quick to fully charge when driving, or when using high-Amp charger – as fast as 2-3 hours. When you allow a lead-acid battery to discharge too much, and it’s very easily done, it carries a memory of the experience.Lithium batteries can charge much more quickly by the vehicle’s engine (via the alternator charging) means that the need for a a fuel cell or generator can be reduced or even eliminated entirely. But it’s important to ensure your vehicle can handle the additional power draw of lithium batteries. I would just like to take this opportunity to thank you very much for replacing my faulty (unit) so promptly and without any fuss. Also known as LiFePO4 or LFP this leisure battery is not just regarded as one of the safest battery's in the range of mainstream li-ion battery's but the nominal voltage of a single cell is 3.

It means it’s really safe and will take good care of itself, preventing over-heating and over or under-charge. Roamer are a battery specialist and not a Solar company however I do not think my 4kw off grid system would up and running now if I had not had all the help from the various members of the Roamer team. Admittedly, we’re yet to see a 300Ah battery on the market which has shelf mode, so far we’ve only seen 100Ah Lithium batteries with this mode. So we’re talking about being able to use the equivalent Lithium battery 14 times more than the equivalent lead-acid battery. Allowing for 4 batteries to be connected in parallel AND 4 batteries to be connected in series is highly impressive.LiFePO4 batteries don’t get sulfation and are significantly less affected by any less than perfect charging-discharging cycles. LiFePO4 batteries are a million miles from earlier incarnations of Lithium batteries, which had safety issues. According to our testing of, at this point, a veritable smorgasbord of LiFePO4 batteries, as well as our analysis of end user feedback to distributors, Renogy have the best quality Lithium Iron Phosphate (LiFePO4) batteries on the market. Weighing only half of the lead-acid counterparts, the caravan battery can be safely discharged to 100% DOD (Depth of Discharge), delivering twice the energy. Lithium batteries hold their voltage as they discharge much better than lead-acid batteries, especially in cold weather.

Lithium batteries’ huge energy capacity means they last longer for each charge and are capable of easily 10 times more cycles (number of times they can be charged and discharged) than lead-acid batteries.When you consider that a Lithium battery lasts forliterally thousands of cycles, charges quickly and can cope with much higher discharge, it’s very clear that Lithium batteries can genuinely provide you with a permanently off-grid lifestyle.
