  • Great replacement for the lead acid battery
Size: Group 47
This battery has been installed in my car for about 2 months now and is working very well. I love the fact that it's much lighter than the seal that acid batteries and it also holds a charge much longer.

  • Wow! That's light
Size: Group 48
I can't speak too much to the performance of this battery as I've only used it a few weeks - in that it's done well. But, after expending much effort wrestling the old battery out of our Enclave, I was able to place the LiFePO4 battery into the under-floor-behind-the passenger-seat battery case with one hand no strain and it fit perfectly. What a difference. ... show more

Excellent product. Fit perfectly and is better suited for low temperature application than lead acid.

  • 1 week of usage
Size: Group 26
Take this with a grain of salt since it's not been used long yet. Swapped my old generator battery with this one, cranked the engine right up without issue 3 separate times already. Taking a charge well. Super light, plenty of power.

  • fit fine, then the 12v fell on its face same day
Size: Group 47
dropped this into the frunk battery tray on an ioniq 5 as a group 47/H5 size swap. polarity matched (L- R+), dimensions sat where the flooded pack sat. connected it, car woke up, first wake after install looked fine. a few hours later the 12v system was weak and the car felt like the aux battery was dying. not a slow multi-month fade. same-day faceplant. listing markets LiFePO4, BMS, 600CCA, start-stop copy, lighter than lead. no clear Ah on the page, which is already a red flag when your car cares about reserve for parasitic drain more than crank theater. I checked with the same meter that read the old oem pack normally. rest and under-load behavior on this unit did not match what you'd expect from a healthy automotive LFP that just "upgraded" your 12v. under load it sagged hard. first start/wake after install can look okay if the BMS is closed and the pack shipped with enough surface charge. then real draw shows up and the pack falls over. healthy LiFePO4 should hold better than this under light accessory load. mine didn't. feels like undersized cells, weak BMS current limits, or both. the gas-car start-stop marketing does not translate into "works in an EV 12v tray." size fit was never the problem. electrical performance was. what I'd want on any cheap LFP listing and didn't get clearly: stated Ah, honest weight, and proof the BMS can feed parasitic load without folding. 600CCA print on the case is marketing wallpaper when the pack can't keep a 12v system happy for a workday. if you're swapping an EV aux pack, treat unknown capacity as the risk, not whether the plastic shell matches H5. install itself was uneventful. clamps torqued, no drama seating the case. the failure mode showed up in use, not at dry-fit. that's why the 1 star. a pack that only looks correct until the car actually draws current is worse than one that never powers on. skip it. return if you still can. don't trust the CCA sticker as proof of reserve. ... show more

Installed it in my 1940 International with a 348 big block. Works great, wish I bought this battery a long time ago. This battery replaced my bad Optima 35. I am shocked how light it is; would buy again in a heartbeat!
