Compatible chargers

These chargers are here because the published figures line up, not because anyone has said they go together — that is our reading of two documents that never mention each other, not a claim by either maker and not a test by us. Even where every figure agrees, these are not established:

Which charge profile the charger is actually set to — several publish four or more, and only one of them is this pack’s chemistry
What it holds the pack at once bulk charging ends, which is a different figure from the one it boosts to, and which some profiles do not apply at all
The charge current the pack will accept, against what the charger delivers into it
Whether the charger can restart a pack its own BMS has already disconnected
The wiring in between — where a converter feeds a distribution panel, the pack is one load on a circuit rather than a device on the end of a lead

Worth confirming with the charger's manufacturer or a dealer before buying.

Epoch Batteries state this pack's charge voltage as 14.6 V — their datasheet reads "14.6".

Neither company names the other, and nobody has tested this pairing.

Set to lithium, WFCO's manual for this converter says it reaches 14.6 VDC in bulk: "boosting the output voltage to 14.6 VDC and allowing the maximum current to flow as required by the loads." That is at or above the figure the pack asks for, where the same maker's WF-8900 tops out at 14.4 V. Bulk runs between one and four hours — the one-hour minimum is for cell balancing rather than charge — and absorption then holds 13.6 V. The lithium profile is selected by a switch on the unit, and an amber LI light shows it is in that mode.
WF-9500-AD Series Power ConverterFigures comparedView charger: WF-9500-AD Series Power Converter →
This converter decides for itself: WFCO's manual says it will "evaluate the charging cycle of a battery, determine the type of battery being used, and then choose the appropriate charging program(profile)", recognising lead-acid, AGM and lithium. Once it has settled on lithium it charges in two stages and reaches 14.6 VDC in bulk, at or above the figure this pack asks for. The condition matters and is theirs, not ours: the 14.6 V depends on the converter detecting lithium.

Devices documented to run on this

The figures below line up. Neither manufacturer states that this pack runs this device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:

The device’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
Conditions attached to the chemistry, such as a speed limit for running on lithium
Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
The charger, which both makers put conditions on and neither supplies
Case size, hold-down and terminal type — fitting the space is not being secured in it

Worth confirming with the device's manufacturer or a dealer before buying.

One of these, on its own, at 12 V.
Only at 12 volts, and on published figures — neither maker has named the other and nobody has tested this pairing — check yours before buying.
Minn Kota ask for “at least a 105 amp-hour rating”, in a paragraph about lead-acid: “The motor will operate with any lead acid, deep cycle marine 12-volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 105 amp-hour rating.” We have not recorded this pack's chemistry, and that figure is a lead-acid one — Minn Kota's table for this motor names “55 lb AGM or Lithium 100Ah 2–4 hours Most common setup” for lithium. Until the chemistry is established the two cannot be compared, so neither is offered as a verdict. This pack is rated 460 Ah and 230 A continuous. Minn Kota attach a condition to the chemistry that no comparison of figures can settle: "speeds higher than 85% for a prolonged period could cause permanent damage to the motor".

Two of these, wired in series for 24 V.
Two in series give 25.6 V and 460 Ah — nearly four times the top of Minn Kota's guidance band, which is a very long day rather than a fault. Epoch permit four strings. Each pack sustains 230 A against a 56 A draw. Worth knowing before buying two: each weighs 40 kg and the pair is 530 mm long apiece, so this is a fitted installation rather than something lifted in and out. Minn Kota's installation manual states their motors are designed for lead acid, that lithium holds a higher voltage for longer, and that running above 85% speed for a prolonged period could cause permanent damage to the motor.

Figures compared — they do not meet

Neither maker names the other. What these chargers publish and what this pack publishes do not meet, and each row below says how. That is our comparison of two documents and not a manufacturer’s refusal — check both against your own equipment before deciding anything.

WF-8900 Series Power ConverterFigures compared — they do not meetView charger: WF-8900 Series Power Converter →
Epoch Batteries state this pack's charge voltage as 14.6 V — their datasheet reads "14.6". WFCO's own manual gives this converter a target output of 13.6 VDC in normal use, rising to 14.4 VDC only in Bulk Mode, which it leaves "until the current draw drops to approximately five Amps, or until the timer reaches four hours (whichever happens first)". So the converter's normal output is below what this pack is specified to charge at, and 14.6 V is above anything the converter produces in any mode. Neither company names the other, and neither has said anything about this pairing.

Do not charge with

The manufacturer states these chargers must not be used with this battery:

24V 15A Lithium Battery ChargerStated incompatibleView charger: 24V 15A Lithium Battery Charger →
Epoch's page for the charger says: "This charger is intended for compatible 24V LiFePO4 batteries. Do not use it on 12V batteries, 36V batteries, 48V batteries, or lead-acid / AGM batteries unless Epoch confirms compatibility for your exact battery and application." The prohibition is conditional: Epoch leave a route open, which is to ask them about a particular battery and use. Nothing on either product's page confirms these pairings, so what is published is a refusal.
