LiTime User Story: Conquering the -20°C Canadian Wild

Living off-grid in a 1970s motorhome in B.C., Canada, Michaelkent faced a brutal reality: in -20°C winters, his standard lead-acid batteries died in just 2 days, leaving his diesel heater powerless.

Following his mechanic’s expert advice, he upgraded to the LiTime 12V 200Ah Lithium battery. The results were game-changing. His runtime jumped from 2 days to 13–30 days, and with the LiTime charger, he reached a full charge in under 2 hours. For Michaelkent, LiTime didn’t just provide power—it provided the freedom to stay warm and stay wild without the constant anxiety of a dead battery.

Michaelkent’s Off-Grid Secret


The Wilderness Enthusiast My name is Michaelkent (or Kent), and I live in the province of B.C., Canada. I live in a 1970's Motorhome with my two dogs all year round. My favorite obsession is wild mushroom foraging wherever and whenever I can. All my interests revolve around being in and near the wilderness—such as fishing, camping, canoeing, and the occasional hunting for survival only. I also enjoy foraging other wild edible plants, as I cherish the peace of the forest and the amazing symphonies of songbirds.

The Winter Challenge Living in a motorhome through the winters here creates quite a challenge in keeping warm. Temperatures can sometimes drop to -20°C or lower, so I purchased a diesel heater to take care of that dilemma. I initially ran the heater on the two auxiliary RV lead-acid batteries. However, I encountered two major issues: the limited run time and the constant necessity to run my vehicle engine every 2 to 3 days just to recharge them.

 The Expert Recommendation My mechanic is the only person I will take advice from regarding my vehicles. He suggested I upgrade to a lithium-ion battery with a 200Ah capacity. Based on his research, he recommended LiTime. Following his advice, I ordered the LiTime 12V 200Ah lithium battery along with the suggested 14.6V 60A lithium battery charger.

Performance & Satisfaction In my experience, the LiTime battery has run the diesel heater at least four times longer than conventional lead-acid batteries. While standard batteries lasted only 2-3 days, the LiTime battery has powered my heater for over 13 days before needing a recharge—and I’m confident it could go 30-plus days with leeway.

Recharging is equally impressive; using my generator and the LiTime charger, it takes 2 hours or less to fully charge after 15 days of steady heater use. I can even run the heater while charging. I am completely satisfied with the capacity and simplicity of LiTime products and will definitely recommend them to anyone looking to upgrade their system.

Sincerely, Michaelkent McCormick
