![]() Mecer 720W 12v Inverter : The inverter can utilize about 75% of total capacity. In most cases it means the battery will last even longer, since it is not being fully drained, which is actually a good restriction. INVERTER APPLICATION NOTE: Each inverter has it's own efficiency, and charging parameters which are not customizable in most cases, so the full capacity might not be usable. The BMS cannot handle the very high instant current requirement. IMPORTANT : These cannot be used to start or operate a vehicle. ![]() Example, a small inverter, with an average 300W load, can run from this battery for 4hrs 15min (1280 / 300 = 4.26). Technically the usable capacity of this 12v 100Ah Lithium battery is double that of a traditional 12v 100Ah sealed lead acid battery, if you only drain 12v SLA 100Ah batteries to 50% as recommended to extend it's life expectancy.Ĭan this battery last long enough for your application? This is complicating for a SLA battery, but simple to calculate for a lithium battery, see the capacity calculation below.ĬAPACITY / RUNTIME : To calculate how long this battery can last in your application, lookup or measure the load power of the device(s) it will be powering in Watts, then divide 1280W with that number. This battery can directly replace a sealed lead acid 12v 100Ah battery in terms of size, charging voltages, and is an upgrade in terms of how many cycles the battery can do (charged and discharged before needs replacing). Other advantages of these Lithium batteries are that there are no fumes, the self-discharge rate is only 3.5% per month (SLA will drain itself dead in 12 months), this battery weights 13kg vs the 28kg average weight of a 12v 100Ah SLA battery, and they can be charged and discharged faster (at higher current). This simply means our lithium battery replacement should last 10 times longer than the typical sealed lead acid (SLA) battery it is replacing. This lithium iron phosphate battery on the other hand, has a high cycle rate of 2000 cycles, it can handle high discharge currents (Max 100A), and the internal battery management system (BMS) protects the battery from overcharging, or discharging too low and a short circuit. But when they are frequently drained (like during load shedding), or placed under high load like a UPS or Inverter places on them, often until the inverter cuts out, then they are basically internally damaged over time, and you will find that you need to replace them very often as they now longer hold charge for long. Only using 50% capacity will increase the cycles to between 400 and 700. Even deep cycle batteries will only cycle 220 times if drained to 80% each time. They are not meant for regularly handling high current and being discharged deeply. ![]() Our smart batteries provide you with 2 x the power that lasts 4 times longer, and charges 5x faster for an outstanding maintenance free Lithium power solution.Using 12v 100Ah sealed lead acid batteries with a small inverter or UPS is not ideal. That’s why we make them with premium materials and cutting edge technology to give you peace of mind when it comes down to safety and performance, so go ahead – power up! Our optional Bluetooth app will allow monitoring capabilities with real time data on charge level as well battery temperature levels which can be important if they’re outside during warmer months (or inside). Read Warranty Information Read Reviews on Products Our battery cost is almost 80% more to make than cheaper alternatives. Our BMS system for overall battery protection is a large superior class electronic component compared to small units used on some batteries. Competitors wrap their batteries in tape and plastic board. This protects that battery through the grueling demands of on water activity. ![]() Our batteries use grade a copper tipped cells to meet the highest standards. Not all lithium batteries are created equal. Above 140☏(60☌), other parasitic reactions are promoted leading to further degradation. Operating your battery below 32☏(0☌) can cause metal deposition at the negative electrode, leading to a short circuit. Therefore, their performance is affected by ambient temperature. Lithium batteries are electrochemical systems, they store electricity as a chemical. Operating temperature is 10☏ to 140☏ or -20☌ to 60☌. Built tournament tough, this is a battery will last up to 5 times longer than your typical SLA battery while providing twice the power at half the weight. The 36 Volt 100 Ah Deep Cycle Battery – our most popular SLA replacement batteries. Tournament Lithium 36V 100 Ah Deep Cycle Lithium Battery ![]()
