9/26/2023 0 Comments Lithium rv batteriesWhile less of an issue in the large-scale solar area, LiFePO4 batteries suitable for RVs are stocked only by a few specialised battery vendors, and by some suppliers of battery charging equipment. Read next: The Springers Solar guide to 12V electrics, lithium batteries CONS This partially offsets their much higher cost. Claims for LiFePO4 vary but vendors suggest about 2000 cycles if routinely discharged to a remaining 20%. If routinely discharged to 50% or so, conventional lead acid and AGM deep-cycle batteries have a typical lifespan of 500-600 cycles. Or via a 2 kW Honda/Yamaha type inverter generator.ĥ – LIFEPO4 BATTERIES ARE CLAIMED TO BETTER WITHSTAND ROUTINE DEEP DISCHARGES Victron’s Quattro range extends to 100 amps or more (for around $5000) and can be run from a 230-volt caravan park supply. A few 12-volt alternators will deliver about 70 amps, but the only realistic (but costly) way above that is via a 230-volt ac charger. While handy for those of 100 Ah or so, the limitation (with RVs) will invariably be the charging source. While even AGM batteries are limited to about 25-30% of their capacity, LiFePO4 batteries can routinely accept 100%-200%. Most can readily cope with the weight and volume of a 400-750 Ah AGM battery bank that will easily cope with even major RV loads, and at well under half the price.Ĥ – LIFEPO4 BATTERIES ACCEPT EXCEPTIONALLY HIGH CHARGE CURRENT It’s less of a benefit, however, for converted coaches. This is a major benefit for camper-trailers, caravans, campervans and smaller motorhomes: most have limited space and weight carrying capacity. LiFePO4 batteries store three to four times the electrical energy of conventional batteries of similar size and weight. Readers with a physics background will realise this provides a correspondingly higher output of about 10% (in terms of watt hours). In practice that voltage is likely to be from 13.1–12.9 volts. It will also maintain substantially constant voltage regardless of the load. The voltage also falls as load increases. Any LiFePO4 suitable for (and in) RV use, however, will provide the peak power required. The voltage of all conventional deep-cycle batteries (as well as AGMs) constantly falls as they discharge. The amp-hour (Ah) capacity you require is that of the total amount of energy that you wish to store and draw from. Given adequate inverter capacity, virtually all your RV’s electrical appliances can be run simultaneously if needed. LifePO4 (lithium) batteries will release energy at any level required in RV use. It’s flexible but expensive – is lithium power right for you? We run through 12 pros and cons of lithium batteries.
