    With drop-in style LiFePO4 batteries gaining in popularity, and our customers asking us for them on a near daily basis, we examined nearly every drop-in LFP battery option available for our customers over a 13 month period. Hands down the Lithioncs 12V125A-G31-5CND-LRB was the clear winner on every front. This is a 125Ah G-31 (actually 1/2" shorter than a typical 13" long G-31) format battery that is capable of engine cranking and includes a Bluetooth Interface. It is also made here in the USA (with the exception of the prismatic LiFePO4 cells). The internal construction of this battery is the best we've seen including massively thick nickel plated busbars and the proprietary Lithionics NEVERDIE® BMS which is designed and built here, in the USA. The battery even features an ON/OFF switch for storage, and for use during hook up to minimize errors and arcing during installation. Another unique feature of the NEVERDIE® BMS offers Power Reserve. This means the battery will self protect, at a safe level, but for an emergency you can re-boot it and have emergency level energy available.

    Lithionics is the only drop-in battery we know of that can furnish a test data sheet that includes test data for every cell in the battery! The cell matching and performance testing of each cell is a pivotal part of a Lithionics battery. Where competitors simply pull cells out of a bin, insert them into the battery, and cross their fingers they match well, Lithionics does not build batteries this way.
