Actively moves charge from highest battery to lowest battery at up to 5 amps.\u003cp\u003e\u003c\/p\u003e\u003cp class=\"text-xl\"\u003eProduct Information\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eBattery Balancer - 48v system (4x 12v batteries in series)\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eNot all batteries are created equal – there are minor manufacturing differences within every battery. When creating a series, or series\/parallel, battery bank to create differing voltages and Ah ratings from individual 12Volt batteries, we can end up with a variance in terminal voltages on each battery. This causes the batteries to become unbalanced.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eCorrect series parallel connection of batteries can help mitigate these differences – but will not eliminate them. Certainly, the correct connection of batteries is an absolute pre-requisite for having a reliable system.\u003c\/p\u003e\u003cp\u003eHowever – even the very best installation will still suffer from imbalance – and the consequence of that is an expensive bank system that can fail prematurely. This is costly, in both time and money.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eHow to control battery imbalance? \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe solution is straight forward – fit a battery balancer.
