20A Smart Car Battery Charger 12V/24V Auto Battery Maintainer for AGM LiFePO4

About this item

Hausprofi's 20A charger lets you set your own charging speed, from a gentle 1A trickle to a fast 20A boost, and works automatically with 12V or 24V systems. It handles AGM, GEL, SLA, Flooded, Calcium and Deep Cycle lead-acid batteries as well as LiFePO4 packs, with smart repair modes for weak or sulfated batteries. Built-in temperature compensation and memory function keep charging safe and consistent, and the extra-long cables make it easy to reach batteries in trucks or tight engine bays. Note: this is a plug-in charger, not a portable jump starter.

• 20A smart charger with adjustable output from 1A to 20A, good for batteries up to 300Ah
• Auto-detects 12V/24V systems, works with AGM, GEL, SLA, Flooded, Calcium and Deep Cycle batteries, plus a dedicated LiFePO4 mode
