Before you buy
Can I use a 10A charger on a smaller lithium battery?
Yes, within the recommended capacity range. Ampmatic adjusts charging current to the battery’s size and condition.
Will it work with any lithium battery?
No. It is designed for 12.8V/13.2V four-cell LiFePO4 batteries, not other lithium chemistries, 16V batteries or lead-acid batteries.
Can it wake up a lithium battery that has shut itself off?
Yes. The LFP mode includes a manually activated BMS reset function for compatible batteries whose protection system has disconnected them after excessive discharge. Follow the manual’s reset procedure.
