Frequently asked questions

Lithium vs AGM — is it worth the price?

Yes — 5x cycle life, half the weight and 80% usable capacity. Pays back in 3 years for full-time campers.

Can I drop-in replace AGM with lithium?

Mostly — but you need a DC-DC charger compatible with lithium charging profile, and a proper BMS-protected battery.

Does it work in cold weather?

LiFePO4 doesn't charge below 0°C. Companion has a heated version for alpine use.
