IT WEIGHTS IN AT ONLY 0.9 KILO
75% LIGHTER& LASTS UP TO 10 X LONGERTHAN A STANDARD BATTERY !!!! Ultramax 12v 7Ah Lithium Nickel Manganese Cobalt Oxide (LiNiMnCo, NMC, NCM) Battery Li[NiMnCo]O2 based Cathode & Graphite based Anode, is the newest generation Li-Ion rechargeable battery for high power applications, such as EV car, E-scooter and E-bike etc. Lithium-Iron Phosphate (LiFePO4) Battery still has a lot of advantages, because of it’s Low Energy Density, this battery is pre-eminently suited for Energy buffers (Stationary Storage) However, we see that NMC batteries are slowly taken the position of the LiFePO4 because of their Higher Energy Density and because prices are leveling The NMC cells compromise between high current rate and high capacity rate. Compared with LiCoO2 series Li-Ion cell, the NMC cells provide higher energy density with lower cost, long cycle life (>1000@1.0C, IEC standrad).
NMC cell has 3.6 +/- 0.5V nominal working voltage and shall be cut-off power at 4.15-4.20V per cell during charging.
NMC is a type of lithium and is a 11.1v battery vs 12.8v of LiFePO4. This battery has an incredible capacity for 12v electronics that are capable of working down to 8v. Common components are LED lights, Vexilar/Marcum flashers, and other lower current electronics. These batteries are also excellent for use in Engine starting, electric bicycle/motorcycle/scooter, golf trolley/carts, power tools, Solar and wind power system, RV, caravan, Back-up system and UPS, Torch, LED light, and emergency light etc., because they do not need maintenance during the off season. There is no equivalent to sulfation and the batteries can be stored in any state of charge without worry of degradation. We recommend 50-100% charge before storage. Another advantage is that running the battery completely down (i.e. leaving the parking light on for a week) will not damage the battery at all, unlike the SLA and Gel batteries, since it has a low-voltage disconnect circuit. THIS LISTING IS FOR: ONE BATTERY12volt 7 AmpHour(12V 7Ah) Nominal Voltage: 11.1v Max. Charge Current: 5AMax. Discharge Current: 10ANominal Capacity: 7Ah LITHIUM NICKEL MANGANESE COBALT OXIDE / NMC BATTERY Ultra Light High Performance. Complete with 2 Hours Lithium battery Charger Can be used anyway around as it is non spillable. Must be stored in charged condition You can now enjoy a lightweight battery that will simply drop in as a direct replacement for your traditional lead acid battery on any application. It weighs in at 0.9kg and measures just 151mm x 65mm x 98mm (5.9″ x 2.5″ x 3.8″), that’s less than 1/4 of the weight of a traditional lead acid battery
COMES WITH A FAST LITHIUM CHARGER (INCLUDED) Best way to chargePartial and random charge is fine; does not need full charge; lower voltage limit preferred; keep battery cool.
Charge MethodsConstant voltage to 4.20V/cell; no trickle charge; battery can stay in charger.Rapid charge = 3h*
Fast charge = 1h Discharge Prevent full cycles, apply some charge after a full discharge to keep the protection circuit alive.
How to prolong batteryKeep cool. Operate in mid SoC of 3080%. Prevent ultra-fast charging and high loads (most Li-ion)
Storage
Store at 40% charge in cool place (40% SoC reads 3.753.80V/cell). Do not go below 2.0V/cell.
The advantages of a NMC battery over LiFePO4 Lithium Iron Phosphate batteries: NCM battery features higher power rating and energy density compared to LiFePO4 battery due to its higher lithium diffusion rate and electron mobility.While NCMs lithium-ions can move in two different directions, LiFePO4s lithium-ions can only move in in one single direction.NCMs lithium diffusion coefficient is 10,000 times faster than that of LiFePO4; in case of electron mobility, NCM is 1,000 times faster than LiFePO4.When lithium and electron mobility are faster, a battery can realize higher power rating and higher energy density. The advantages of a LiFePO4 Lithium Iron Phosphate battery over conventional lead-acid batteries: High energy density: more energy with less weight;High charge currents (shortens the charge period);High discharge currents (enabling for example electrical cooking on a small battery bank);Long battery life (up to six times the battery life of a conventional battery);High efficiency between charging and discharging (very little energy loss due to heat development);Higher continuous power available.
