Before connecting multiple batteries, confirm the approved battery combination, wiring and charging arrangement with FLYFINE.

Frequently Asked Questions

Which capacities are available?

The 12.8V range includes 50Ah, 100Ah and 205Ah. The 25.6V range includes 100Ah and 205Ah.

Is Bluetooth included as standard?

No. Bluetooth and app monitoring are listed as optional. Request this configuration when placing your order.

Can these batteries replace a lead-acid battery?

They can be considered for compatible 12V-class or 24V-class systems. Confirm the equipment voltage range, charger settings, current demand and installation dimensions before replacement.

Can the batteries be connected in series or parallel?

The datasheet lists up to four units in series or up to four in parallel. This does not establish approval for every combined series-parallel arrangement. Confirm your intended configuration with FLYFINE.
