Gel blasters are enormously fun toy guns designed for indoor and outdoor shooting games and competition. They can shoot one gel ball after another, and their hoppers can deliver hundreds of gel balls into the chamber for extremely accurate shots. However, they are not simply mechanical toys based on a spring.

Batteries for gelblasters are based on lithium polymer, which provides excellent power in a very small package. For the best possible experience, you will want to care for this battery as it is obviously critical to the successful operation of your gel blaster. However, these batteries, also known as lipo batteries, require a higher standard of care than traditional batteries. Without the proper care, you can end up with a dead battery that will not hold a charge or a battery that could end up as a safety hazard.

1. Maintenance

Lipo batteries can have a soft or squishy feel to them. As such, you might be strangely tempted to poke or press the outer casing of the battery. Do not do this as it can damage the inside of the battery cell.

2. Gun care

Batteries store and deliver electricity while gel blasters shoot damp gel balls, and this mixture of moisture and electricity can become a problem if you do not properly drain the gel balls. With this in mind, after you have grown your gel balls to their maximum size, you should drain them such that they feel slick without dripping. When you fill your gel blaster, you should never pour dripping gel balls into the hopper. If you do, the water can seep into the battery slot and cause a short circuit.

Additionally, if you do, for some reason, fill the blaster with gel balls that are a little too wet, you should protect the battery by upturning the blaster and allowing the excess water to drain out. Prior to using the blaster, you should wipe the entire casing down until it is dry. Once you are done shooting, you should disconnect the hopper, empty all the balls, and allow any excess water to drain.

3. Inspection

Although the outer casing of a lipo battery might be softer than that of a conventional battery, it should never puff up or expand. Prior to using any battery, you should inspect it for any malformations. Puffiness can sometimes occur as a result of improper charging, and any such batteries should be discarded or exchanged. If you notice any type of swelling, you should ensure to not charge the battery. Finally, prior to each use, you should inspect the battery for damage that includes puncturing or denting.

4. Storage

Ideally, you should store your lipo batteries in a dry, cool place that is free of any conductive materials. Additionally, you should not store them exposed in a drawer or anything that might create static electricity. You should never store your batteries in the gun while it is not in use.

If you have a voltmeter, you should measure the charge and ensure the batteries are at the ideal voltage for storing. If the batteries are less than the ideal voltage, you should charge the battery prior to storage. On some chargers, you can set the charge to “storage,” which will charge the battery to the ideal voltage.

During storage, batteries should be maintained at a temperature between 40 degrees and 120 degrees Fahrenheit. If temperatures exceed 120 degrees, the lifespan of the battery will be reduced.

The ideal voltage for any stored battery is 3.8 volts with an allowable positive or negative variance of .05 volts per cell. That said, batteries might vary, so the manufacturer’s specified storage voltage supersedes any other voltage recommendation.

5. Charging

When you charge the battery, you should do so with it placed in a fireproof bag. Additionally, many chargers exist for many types of batteries. With this in mind, you should only use a charger designed to charge lipo batteries. You should also ensure that the model of charger you are using is approved for the specific battery you want to charge.

A charging battery should never be left unsupervised, and you should never charge a battery in a vehicle or while the battery remains in the gel blaster.
