LiPo battery safety.
LiPo batteries power most modern AEGs, and they are brilliant, light, powerful and long-lasting. Treated carelessly, though, they can be a genuine fire risk. Here is how to charge, store and handle them safely.
Charging safely
- Use a proper balance charger and set it to the correct cell count for your battery. Balance charging keeps the cells even, which is both safer and better for battery life.
- Charge in a fireproof bag or on a non-flammable surface, well away from anything that could catch.
- Never leave a LiPo charging unattended, and never charge overnight while you sleep.
- Stop immediately if a battery gets hot, puffs up or looks damaged.
Storage: the bit people forget
LiPos do not like being left fully charged or fully flat. For anything more than a day or two, store them at storage charge, about 3.8 volts per cell. Most smart chargers have a "storage" mode that sets this for you automatically. Keep them in a fireproof bag, somewhere cool and dry, away from children. This single habit does more for battery life and safety than anything else.
Never over-discharge
Running a LiPo until the gun stops is one of the most common ways to wreck one. Draining the cells too low damages the battery and can make it unsafe to charge again. Two ways to avoid it:
- Fit a MOSFET with a low-voltage cutoff, which shuts the gun off before the battery drops too far. Many players consider this essential with LiPos.
- Swap batteries early. If the rate of fire noticeably slows, change to a fresh battery rather than draining the last out of it.
Choosing a battery: voltage and connector
When you buy a LiPo, two things need to match your setup:
- Voltage: airsoft LiPos are commonly 2S (7.4V) or 3S (11.1V). Higher voltage means a faster rate of fire but more stress on the gearbox, so check what your gun is built to handle before going up.
- Connector: match the connector type your gun uses (small Tamiya, Deans/T-plug and similar are common). The wrong connector will not plug in.
- Size: the battery has to physically fit the space in your replica, so check the dimensions.
Damage and disposal
A swollen, puffed or physically damaged LiPo is done, retire it straight away and do not try to keep using it. Dispose of LiPos through battery recycling or e-waste drop-off points, never in general rubbish or kerbside recycling where they are a fire risk. Many NZ retailers and councils have battery recycling points for exactly this.
