OEM Lithium Battery Cross-Reference & Drop-In Replacement Engineering
LBC engineers form-fit-function replacement and second-source 12V–144V+ LFP and NMC battery programs for North American OEMs facing long lead times, end-of-life notices or allocation limits. References may include Aegis Battery, Inventus Power, Flux Power, RELiON and Lithionics series. Catalog programs start at 10 units; custom designs at 25. Compatibility requires review of the exact incumbent specification.

Start with the incumbent specification
Send the current part number and equipment requirements. Aegis Battery, Inventus Power, Flux Power, RELiON and Lithionics references are reviewed individually for a possible second-source design. The matrix below is a requirements framework, not a verified equivalence or interchangeability list.
Catalog programs start at 10 units; custom designs at 25. Lead times run from weeks to months and are confirmed in the quote.

OEM buyer questions
Is a matching voltage enough to confirm a drop-in replacement?
No. LBC reviews the full voltage window, charge profile, continuous and peak current, regeneration, enclosure, mounting, connectors, BMS protocol and fault behaviour. A catalog voltage match is a starting point, not confirmed interchangeability.
Which incumbent references can we submit for engineering review?
Submit your current Aegis Battery, Inventus Power, Flux Power, RELiON or Lithionics part number and specification details. These names identify customer-supplied comparison references, not an affiliation or a pre-approved equivalent.
What is needed for a form-fit-function cross-reference?
Provide the incumbent part number, voltage window, capacity or runtime, load profile, envelope, connector and pinout, charger, communications and program volume. Paste the part number and specification details into the request; the team can arrange a document exchange.
Can a replacement program use a custom enclosure or BMS interface?
Yes. Custom programs start at 25 units and can be reviewed around your enclosure, connector and BMS communications. Catalog reference-design programs start at 10 units. Engineering scope, compatibility and delivery are confirmed in the quote.
