It adds Bluetooth monitoring and a self-heating function so the battery can still accept a charge when the temperature drops below freezing.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eBattery space in a caravan is almost never a neat cube. The underseat form factor exists because the usable volume in a van is wide and flat, not tall, and a conventional upright 200Ah case simply will not go where you need it. Two hundred amp-hours is the sweet spot for most touring setups: it will carry a compressor fridge, lights, water pump, charging and a reasonable amount of inverter use through a night and a cloudy morning without anxiety. The self-heating function is the part people underestimate in South Africa. We think of the country as hot, but a winter night in the Karoo, the Drakensberg or the Eastern Cape highlands drops below zero regularly, and lithium cells must not be charged below freezing without damage. This battery warms itself before accepting charge instead of simply refusing.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnderseat low-profile case\u003c\/strong\u003e – designed to fit shallow spaces where a standard upright battery will not go.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-heating function\u003c\/strong\u003e – warms the cells so the battery can safely accept charge in sub-zero conditions instead of locking out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth monitoring\u003c\/strong\u003e – state of charge, voltage, current and cell health on your phone, without wiring in a separate display.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiFePO4 chemistry\u003c\/strong\u003e – stable, long-cycling lithium iron phosphate, not the higher-energy chemistries used in laptops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated battery management system\u003c\/strong\u003e – protects against over-charge, over-discharge, over-current, short circuit and temperature extremes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable capacity\u003c\/strong\u003e – unlike lead-acid, you can genuinely use most of the rated capacity without shortening its life.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOff-road caravans and campers where battery space is shallow rather than deep.\u003c\/li\u003e\n\u003cli\u003eLong transits and extended bush camping where a fridge must run for days.\u003c\/li\u003e\n\u003cli\u003eWinter touring in the Karoo, Drakensberg or highveld where nights drop below freezing.\u003c\/li\u003e\n\u003cli\u003eSystems feeding a 2000W or 3000W inverter that need real current delivery.\u003c\/li\u003e\n\u003cli\u003eUpgrading from a tired lead-acid bank without giving up floor space.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003eOur workshop specifies and fits Renogy systems throughout the \u003cstrong\u003eWestern Cape\u003c\/strong\u003e.

A 200Ah lithium battery is heavy, and on corrugated gravel an unrestrained battery becomes a projectile, so use a proper hold-down and mount it low and close to the axle line where possible. Fuse the positive lead as close to the terminal as practical and size the cable for the largest load you intend to run, which is usually the inverter rather than the fridge. If you are charging from the vehicle while driving, use a DC-DC charger rather than a simple split-charge relay, because a lithium battery will otherwise try to draw more current than your alternator wants to give. Batteries can be paralleled for more capacity, but do it with matched units, equal-length cables and a common busbar so the current shares evenly.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003eBrowse the rest of our \u003ca href=\"\/collections\/lithium-batteries\"\u003elithium batteries\u003c\/a\u003e range if you are weighing up capacity, and keep the bank topped up with panels from our \u003ca href=\"\/collections\/solar-panels\"\u003esolar panels\u003c\/a\u003e collection and a matched unit from our \u003ca href=\"\/collections\/solar-charge-controllers\"\u003esolar charge controllers\u003c\/a\u003e range.

Rather than simply blocking the charge, this battery uses power to warm the cells to a safe temperature first, then accepts the charge. It matters on cold winter mornings inland.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is 200Ah of lithium different from 200Ah of lead-acid?\u003c\/strong\u003e\u003cbr\u003eUsable capacity. With lead-acid you would typically only draw about half before you start shortening its life, so a 200Ah lead-acid bank behaves like roughly 100Ah. With LiFePO4 you can use most of it, and the voltage stays higher under load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it fit under my dinette seat?\u003c\/strong\u003e\u003cbr\u003eThat is exactly what the underseat case is designed for, but measure your space before ordering.

A DC-DC charger for alternator charging and an MPPT controller set to a lithium profile for solar is the normal combination.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect two of these in parallel?\u003c\/strong\u003e\u003cbr\u003eYes, to increase capacity. Use matched batteries at a similar state of charge, equal-length cables and a proper busbar so they share current evenly.\u003c\/p\u003e","brand":"Renogy","offers":[{"title":"Default Title","offer_id":48301650346169,"sku":"RBT12200LFP-SHBT-G1-SA","price":21195.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/4587\/6409\/files\/1-200ah.jpg?v=1784806522","url":"https:\/\/www.4mattcampers.co.za\/products\/renogy-pro-12v-200ah-underseat-smart-lithium-battery-with-bluetooth-self-heating","provider":"4Matt Campers","version":"1.0","type":"link"}
