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:

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.

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

Works great

I had a flow zone dealer tell me this battery wouldn’t work in my sprayer. I charged it and installed. Works great, but a little expensive.
