It is the neat way to build a small 24V house bank without stacking two 12V batteries in series and hoping they stay matched.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eIf you have decided to run a 24V system, the tidiest starting point is a battery that is already 24V. Wiring two 12V batteries in series works, but you double the connections, you have to keep the pair balanced, and one weak cell drags the whole string down. A single 24V block removes all of that. At 25Ah it is deliberately modest, which suits a light off-road trailer, a rooftop-tent vehicle or a small camper where the loads are a fridge, lights, water pump and charging, rather than air conditioning. LiFePO4 chemistry is the right call for South African touring. It tolerates the heat you get in the Karoo and the Kalahari far better than lead-acid, it does not sulphate if you leave it partly charged between trips, and you can use effectively all of the rated capacity instead of stopping at half.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e24V nominal in a single block\u003c\/strong\u003e – no series pairing, no matched-battery headaches, half the terminals to corrode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLithium iron phosphate chemistry\u003c\/strong\u003e – stable, safe and far more tolerant of heat and partial charge than lead-acid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoughly 2000 charge cycles\u003c\/strong\u003e – years of weekend touring rather than a battery you replace every second season.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull usable capacity\u003c\/strong\u003e – you can draw the rated amp hours instead of stopping at 50% the way you must with lead-acid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e25A maximum charge current\u003c\/strong\u003e – a full charge in about 1.5 hours from a suitably sized charger or DC-DC unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in battery management system\u003c\/strong\u003e – protects against over-voltage, under-voltage, over-current and temperature extremes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic cell balancing\u003c\/strong\u003e – keeps the internal cells matched so capacity does not drift away over time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6 kg and 166 x 197 x 168 mm\u003c\/strong\u003e – light enough to lift into a nose cone one-handed and small enough to fit where a lead-acid block never would.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM8 terminal bolts\u003c\/strong\u003e – standard ring lugs, no proprietary connectors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSmall off-road trailers and camper trailers moving to a 24V electrical system.\u003c\/li\u003e\n\u003cli\u003eRooftop-tent and bakkie canopy builds where space and weight are the limiting factors.\u003c\/li\u003e\n\u003cli\u003e24V inverter installations that need a compact starter bank with room to expand later.\u003c\/li\u003e\n\u003cli\u003eFridge, lighting, pump and device-charging loads on weekend and week-long trips.\u003c\/li\u003e\n\u003cli\u003eReplacing a tired pair of series-wired 12V lead-acid batteries with something lighter and longer-lived.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003e4Matt Campers supports Renogy builds right across the \u003cstrong\u003eWestern Cape\u003c\/strong\u003e.

It is light, and a light battery moves further on corrugations than a heavy one. Torque the M8 terminal bolts to a firm, even setting and use correctly crimped ring lugs. Charging is where people get caught out: a 24V battery needs a 24V charge source. A standard 12V alternator will not charge it directly, so a DC-DC charger configured for a 24V output is the usual answer, or a 24V-capable MPPT controller from your solar array. Do not charge below freezing unless the battery is a self-heating model, and this one is not. If you plan to expand the bank later, buy identical batteries and add them at the same time rather than mixing an old block with a new one.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003eFeed it from our \u003ca href=\"\/collections\/solar-panels\"\u003esolar panels\u003c\/a\u003e through a 24V-capable unit in \u003ca href=\"\/collections\/solar-charge-controllers\"\u003esolar charge controllers\u003c\/a\u003e, and turn it into 230V with a matched unit from \u003ca href=\"\/collections\/inverters-inverter-chargers\"\u003einverters and inverter chargers\u003c\/a\u003e.

If the fridge is your only load and you have solar on the roof, it is comfortable. If you also want to run an inverter for a kettle, size up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I charge it from my vehicle alternator?\u003c\/strong\u003e\u003cbr\u003eNot directly. A 12V alternator cannot push charge into a 24V battery. You need a DC-DC charger with a 24V output, which also protects the alternator from being loaded flat out.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I wire two of these in series for 48V?\u003c\/strong\u003e\u003cbr\u003eCheck the datasheet and confirm with us first. Series configuration is not universally supported on every Renogy model and getting it wrong voids the BMS protection. Parallel expansion at 24V is the usual route.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if I leave it standing over winter?\u003c\/strong\u003e\u003cbr\u003eUnlike lead-acid, it will not sulphate. Store it around half charge in a cool place and it will be fine for months. Do not store it fully flat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it safe to mount inside the living area?\u003c\/strong\u003e\u003cbr\u003eLiFePO4 does not vent hydrogen the way flooded lead-acid does, so an internal mount is normal practice.
