The shunt sits in series on your battery negative: B- to the battery, P- to the load and charger negative. All current must pass through it, or the meter can't count it. A red wire from battery positive to B+ powers the meter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it work with LiFePO4 and my system voltage?\u003c\/strong\u003e\u003cbr\u003eYes. It covers lead-acid, LiFePO4, ternary lithium, polymer lithium, NiCd and NiMH on systems from 8 to 120V DC. It counts current instead of reading voltage, so a flat lithium curve doesn't leave you guessing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat battery bank size can it handle?\u003c\/strong\u003e\u003cbr\u003eYou can set capacity from 0.1 to 9999 Ah, so it suits a small battery or a big house bank. Choose the shunt by your highest current draw, not by battery size. That is what the current range is for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich current range should I choose?\u003c\/strong\u003e\u003cbr\u003eChoose by the highest current your system reaches: 50A (0-75A), 100A (0-150A), 350A (0-500A) or 500A (0-750A). Each kit pairs the meter with its matching shunt, and different ranges must not be mixed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much room do I need for the shunt and display?\u003c\/strong\u003e\u003cbr\u003ePlan a spot for the shunt and a 94.0 x 57.0 mm (3.70 x 2.24 in) cutout for the display. The display snaps in from the front. Shunts run from 47x41x13 mm (1.85x1.61x0.51 in) to 122x60x32 mm (4.80x2.36x1.26 in).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill it drain my battery?\u003c\/strong\u003e\u003cbr\u003eThe meter's working draw is about 10mA and its static draw is 1.0mA, low enough to ignore on a house bank. The green backlight draws more while it is lit: 50mA on the 50A spec, 100mA on the others.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes it have Bluetooth or an app?\u003c\/strong\u003e\u003cbr\u003eNo. This is a wired meter with its own backlit screen, so you read everything right at the display. No phone needed, no app to open at 2am.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it for my RV, boat or cart?\u003c\/strong\u003e\u003cbr\u003eLikely yes. Typical uses are RVs, yachts, golf carts, forklifts and energy storage, on systems from 8 to 120V DC. Pick the shunt by the highest current your setup draws.\u003c\/p\u003e","brand":"PrimyDeals","offers":[{"title":"100A shunt (0-150A)","offer_id":49751424630939,"sku":"PD-amplume-battery-monitor-shunt-1","price":359.99,"currency_code":"USD","in_stock":true},{"title":"500A shunt (0-750A)","offer_id":49751424663707,"sku":"PD-amplume-battery-monitor-shunt-2","price":479.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/1712\/7067\/files\/battery-monitor-shunt__p6_v1.png?v=1791485273","url":"https:\/\/primydeals.com\/products\/amplume-battery-monitor-shunt","provider":"PrimyDeals","version":"1.0","type":"link"}
