ProMariner ProSportHD 20 Plus 3-Bank Charger (44021)
- Brand:

- Part no:
- 44021
A 20 A, three-bank, IP67 waterproof onboard charger for three 12 V batteries, which ProMariner says gives a full charge in 8 to 10 hours. Its AGM profile charges to 14.7 V and maintains at 13.6 V, so compare that with your battery maker's settings; its LiFePO4 profile is for ProMariner-approved lithium batteries only. ProMariner says waterproof chargers are for batteries not in use while charging and recommends a charger of about 10 percent of the bank's total amp-hours, and its manual asks for a GFCI-protected outlet.
Our take
A fit for a boat with three 12 V batteries that wants an IP67-rated 20 A charger. It is made for LiFePO4, flooded, AGM and gel, with an 8 to 10 hour full charge. Skip it if you run other lithium packs or need quick top-ups, and check its charge settings against your battery maker's figures.
