Our take on the Abyss On-Board 36V 20A High-Precision Marine Lithium Charger

The Abyss On-Board is a 36V lithium marine charger rated at 20A, built to be wired into a boat and left there. It is aimed at owners of 36V lithium trolling motor or house banks who want a fast, fixed installation rather than a portable charger. The high-precision label points to tight voltage control, which matters for lithium packs. Against portable 36V chargers it trades flexibility for a permanent, higher-current setup.

Questions and answers

Is 20A too much for my 36V lithium battery?
Check your battery's maximum charge current. Many 36V lithium packs accept 20A, but smaller ones cap lower and the charger should be matched to that limit.
Can it charge lead-acid batteries?
It is specified for lithium only. Lead-acid and AGM banks need a charger with the right charge profile.
Does it work as a portable charger?
It is an on-board unit meant to be mounted and wired into the boat. For charging away from the boat, a portable charger fits better.
What input voltage does it need?
It runs on 36V input, so confirm your boat's supply matches before wiring it in.
Can it charge more than one battery bank?
The listing describes a single 36V, 20A charger. If you run separate banks, plan for one unit per bank or a multi-bank charger.
Where is the Abyss On-Board 36V 20A High-Precision Marine Lithium Charger cheapest?
At West Marine, for $499.99, as of our latest check.
