Key Points

Eco-friendly

1. Dyness B3 3.6kWh 48V Lithium Ion Battery and other Lithium-ion batteries contain relatively low levels of toxic heavy metals found in other types of batteries, such as lead-acid and nickel-cadmium (NiCd) batteries.
2. Cadmium, lead, and mercury have been battery stalwarts for years, but prolonged exposure to, and inadequate disposal of these metals is harmful to humans, animals, and plants.
3. Although Li-ion batteries are safer than many other types of batteries they still require proper recycling, so never put your used batteries in with your regular rubbish.

Lightweight and compact

1. Electrodes commonly used in lithium-ion batteries, lithium and carbon, are lightweight on their own, making for much smaller and lighter batteries than their older counterparts such as lead-acid batteries.
2. For comparison’s sake, a typical 51Ah (= ampere-hour) lithium-ion battery weighs about the same as a 24Ah lead-acid battery (about 6-7kg), but provides over twice the capacity.
3. This particular characteristic of lithium-ion batteries is especially convenient in head torches, as we can increase the light output and runtime significantly without adding bulk and weight to the battery pack (and on your head!).

High energy density = A bigger punch

1. Lithium is a highly reactive element with the ability to release and store large amounts of energy, allowing li-ion batteries to pack a high energy capacity in a small size.
2. This translates to lithium-ion batteries lasting much longer between charges than other rechargeable batteries, while still maintaining their high level of performance.
3. A typical lithium-ion cell (= battery) has an average cell voltage of 3.6V, whereas a nickel-metal hydride (NiMH) cell averages at 1.2V, meaning three Ni-MH batteries are required to match the output of a single lithium-ion battery.

Low maintenance

1. Older types of rechargeable batteries, such as nickel-cadmium or nickel-metal hydride batteries had a so-called “memory effect”, or “lazy battery effect”:
2. If they were repeatedly partially discharged before being recharged, ultimately the battery would only deliver the amount of energy that was used during the partial discharges before its voltage would drop.
3. To avoid this, NiCd and NiMH batteries would need to be regularly maintained by completely discharging and recharging them.
4. Dyness B3 3.6kWh 48V Lithium Ion Battery and other Lithium-ion batteries don’t suffer from the memory effect, which means they always give up their last bit of power, and you can recharge them whether you’ve used 100% or 25% of their capacity with no pesky maintenance needed!

More charge cycles

1. Quality lithium-ion batteries last about a 1000 full charge cycles. A full charge cycle is when the battery is discharged to flat and then recharged to full, so using your battery until it’s at 75% capacity and then plugging it into recharge doesn’t constitute a full charge cycle.
2. When your battery has recharged back to full, you can still use the 75% of the capacity that you were left with before you recharged your battery; only then has your battery gone through a full charge cycle.

Low self-discharge rate

1. Dyness B3 3.6kWh 48V Lithium Ion Battery and other Lithium-ion batteries also have a relatively low self-discharge rate. Self-discharge is a natural, irreversible phenomenon for batteries, where chemical reactions inside the batteries reduce their capacity even when the battery is not being used.
2. The self-discharge rate of lithium-ion batteries peaks at about 5% within the first 24 hours after charging the battery, and then tapers off to 1-2% per month. In comparison, nickel-based rechargeable batteries lose about 10-15% of their capacity after charge and another 10-15% per month.

Voltage Protection

Dyness B3 3.6kWh 48V Lithium Ion Battery

Low Voltage Protection in Discharging 

• When any battery cell voltage or total voltage is lower than the rated protection value during discharging, the over-discharging protection is activated, and the battery buzzer makes an alarm sound.
• Then battery system stops supplying power to the outside. When the voltage of each cell back to rated return range, the protection is over.

Over Voltage Protection in Charging

• Battery will stops charging when total voltage or any battery cell voltage reaches the rated protection value during charging stage. When total voltage or all cell back to rated range, the protection is over.
