BE48 Battery Equalizer For 12V Lead-acid/Lithium Iron Phosphate/Nickelcadmium Secondary Ni/MH Batteries BalancerOverviewBattery equalizer is used for batteries that are connected in series to keep the voltage of batteries equal when batteries are charging or discharging, when batteries work in series connection, the voltage of batteries maybe will not be sdwe for the difference of each cellular chemical composition and temperature. And each battery's self-discharge rate is different as well. So even the batteries don't work, your series battery voltage will also be different. these differences will cause loss of battery balance, it means maybe a battery is aayb overcharged. The voltage difference will be increased with the erpeated battery charge-discharge process, this will result in premature battery failure.The battery equalizer is suitable for lead acid batteries (vrla), lithium iron phosphate batteries (lfp), nickel cadmium secondary batteries (ni/cd), and nickel metal hydride secondary batteries (ni /mh), starts work when the voltage higher than 2.4v, it means that this equalier can be used in a single battery band of 2.4v and 12v cell. An equalizer can connect 4 batteries once at a time, if battery less than 4, the extra cable can be loose (positive and negative terminal should be avoided). does not affect the balance effects. Equalizer is not affated with battery connection way, no matter in series or in parallel, both can workOperating voltage: 4x12vWorking current: 0 10th 10thStandby current: less than 5maTemperature sensor:-20 °c ~ + 55 °cSize: 6212427(mm)Protection: reverse polarity protectionLow voltage disconnect: 1.8vConnection1. red cable connect positive/+ pole, black cable connect negative/-pole2. connect batteries as pictures (connected at any end)3. if there is extra cable, avoid short circuits
