Dropped a couple of these into the camper late last year...

Direct drop in replacement. Charges well off alternator as well as solar via standard SLA solar reg. Used it over summer with a few camping trips and was very pleased with the performance. The price is also a welcome change from what I have previously seen LFP batteries selling for in the past.

The only problems that I have found so far are:
1. Due to the voltage holding above 13.2v when charged, my dual battery controller does not cut out and the LFP battery 'discharges' into the vehicle lead acid battery (haven't swapped this one yet). Added an extra ignition switched relay to solve this.
2. They do not respond well to 'over discharge' (then again neither do SLA, but these are worse) so you may need to add a low voltage cutout on your equipment.

Disclosure: I have absolutely no (zero, none, nill) affiliation with this company, I'm just happy with the product, and thought others might benefit.
