18V/5.2Ah Lithium-Ion Battery Pack


Rechargeable 18-Volt / 5.2 Amp Hour Lithium-Ion battery for use exclusively with FlowZone sprayers. TriZone™ technology prevents against over heating, overcharging, and incompatible voltage protection.


Rechargeable lithium-ion battery for FlowZone® sprayers. This durable battery pack is rated for up to 1,000 charge cycles. 

Spray continuously for over 3 hours with 3X protection battery technology so that you never have to worry about:

1. Overheating - cuts current if temperature becomes too hot

2. Over charging - will stop charging at 100% charge level

3. Voltage protection - will not accept higher amperage input

Never be surprised by a dead battery thanks to the LED indicator lights on the front of the battery. Pressing on the battery icon will show the charge left on your battery and the lights will blink as the battery is charging.

*NOTE* Only charge using the 21V/2.5A Quick-Charger (Part #: FZAAEL)

They are a real company

I tried to get customer service through their website and it wouldn’t let me upload a photo or delete entries uploaded so I was stuck. They called me and made it right. Thank you flowzone for being a real company and following through on customer service and standing bye your great products.

Great Customer Service

A Cyclone 3 I ordered from Do it yourself pest control arrived without the battery. I called FlowZone and told Andres Espinoza my dilemma. He took my information and a couple of days later I received a battery. Great customer service
