This NMC battery comes with:
✅ 1-Year Warranty
✅ Free Delivery within the UK *
ABOUT THE PRODUCT:
Li [NiMnCo] O2-based Cathode & Graphite-based Anode, is the newest generation Li-Ion rechargeable battery for high-power applications, such as EV cars, E-scooters, E-bikes etc.
This battery has an incredible capacity for 12v electronics that are capable of working down to 8v.
- It has a low-pressure relief valve
- Can be used in any position
- Has excellent recovery from deep discharge
- Low self-discharge of just 3% per month
- Maintenance free
- Terminals are standard 4.75mm Wide Fast-on (Spade) connectors
The NMC cells compromise between a high current rate and a high capacity rate. Compared with LiCoO2 series Li-Ion cell, the NMC cells provide higher energy density with lower cost, and long cycle life (>1000@1.0C, IEC standard).
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.
Nominal Voltage: 11.1v
Max. Charge Current: 15A
Max. Discharge Current: 15A
Nominal Capacity: 18Ah
APPLICATIONS:
Suitable for cyclic and standby power applications.
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.
CHARGING:
Best way to charge: Partial and random charge is fine; does not need full charge; lower voltage limit preferred; keep battery cool.
Charge Methods:
Constant 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 battery life: Keep cool. Operate in mid SoC of 30–80%. Prevent ultra-fast charging and high loads (most Li-ion)
STORAGE: Store at 40% charge in cool place (40% SoC reads 3.75–3.80V/cell). Do not go below 2.0V/cell.
