Compatible platforms

These figures match. Nothing states that the packs are interchangeable — that is our observation of published specifications, not a claim by the manufacturer or a test by us. Even when every stated figure agrees, these can still differ:

  • BMS communication — many packs authenticate with the platform over a data bus
  • Maximum discharge current, which the capacity figure does not express
  • Pin assignment inside an identical connector shell
  • Mounting rail, lock and cradle — a shared case is a shared shape, not a fit
  • Firmware or serial pairing, where the manufacturer uses it

Worth confirming with the manufacturer or a dealer before buying.

Only the house bank, and Winnebago fit TWO of them — this is not the chassis starting battery — check yours before buying. — applies to Winnebago Travato 59K, Winnebago Travato 59G, Winnebago Solis 59P, Winnebago Solis 59PX

Sources do not establish: which terminal type the van expects. Group 31 comes as 31T with top posts and 31A with threaded studs, and the two share an envelope — so a pack of the right SIZE can still have the wrong POSTS for the cabling. Winnebago do not state which their trays are wired for, and this pack is a 31T. Check the terminals before buying.

Do not charge with

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

  • PD4500LI Series Power Control CenterStated incompatibleView charger: PD4500LI Series Power Control Center →

    Progressive Dynamics state it outright about this converter: "The 4500LI series converter/chargers are designed to recharge lithium iron phosphate (LiFePO4) batteries only. DO NOT USE TO RECHARGE LEAD/ACID BATTERIES!" This pack is AGM, which is a lead-acid chemistry, so their sentence covers it. They say nothing about packs of other chemistries and nothing here extends it past what it covers.
