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.
Redodo state this pack's charge voltage as 14.4 ± 0.2 V — their datasheet reads "Charge Voltage: 14.4V±0.2V".
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.
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.
