Compare LiTime and Battle Born at the exact SKU level using energy, BMS limits, temperature features and written warranty terms.
Two of the most common LiFePO4 brands in US van builds are LiTime (budget value leader) and Battle Born (premium, US-made). Here's how they actually compare for a house battery.

Price comparison
| LiTime 100Ah | Battle Born 100Ah (Heated) | |
|---|---|---|
| Price | ~$220 | ~$799 |
| Usable capacity (80%) | ~80Ah | ~80Ah |
| Warranty | ~3-5 years (model-dependent) | 10 years |
| Self-heating | Not on standard models | Yes |
| Manufacturing | China | USA |
At roughly 2-3x the price per Ah, Battle Born is firmly in premium territory. The question is whether its specific advantages matter for your build.
Where Battle Born's premium pays off
- 10-year warranty — significantly longer coverage, useful if you're keeping the van for the long haul.
- Built-in heating (heated models) — lets the battery charge in temperatures that would otherwise block charging on a standard LiFePO4 BMS (below 32°F/0°C). If you regularly camp in cold conditions and don't want to manage this manually, this is a real convenience.
- US-made — matters to some buyers for support and supply chain reasons.
Where LiTime makes more sense
- Budget-conscious builds — LiTime's price-per-Ah lets you size a larger bank for the same money, or free up budget for solar/inverter.
- Moderate climates — if you rarely camp below freezing, the heated function isn't doing much for you, and a standard (non-heated) LiFePO4 battery from any reputable brand works fine.
- First builds / smaller systems — LiTime's 100Ah and 200Ah units are widely used as a starting point in budget-focused conversions.
The 200Ah size is often the better value step-up
Rather than two 100Ah batteries in parallel, a single 200Ah unit (LiTime 200Ah, ~$399) is simpler to wire (one set of terminals, one BMS) and often a similar total cost to two smaller units — see wiring batteries in parallel for when parallel still makes sense.
The honest take
Both are legitimate LiFePO4 batteries that will work well in a correctly wired system (proper Class T main fuse, LiFePO4-compatible chargers — see LiFePO4 vs AGM). The decision comes down to budget vs. warranty/cold-weather convenience, not a quality gap at the cell level.
Worked planning check
Ask each seller the same five questions: permitted charge current, continuous discharge, cold-charge behaviour, parallel limit and return process. Add any necessary heating or monitoring to both prices. Without equivalent features and terms, a price-per-Ah comparison is incomplete.
The figures or dimensions in this example are explicit planning assumptions, not a product test or an installation specification. Replace them with your equipment data and actual measurements.
Planning questions
How much energy is in a 100Ah lithium battery?
At nominal 12.8V, the arithmetic is 1,280Wh. Delivered energy is lower after your reserve, losses and operating limitations; it is not a measured capacity result.
Can I mix battery brands or capacities?
Only with explicit manufacturer approval for the complete arrangement. Chemistry, voltage, age, current sharing and BMS behaviour can make a seemingly simple combination unsuitable.
Can lithium batteries charge in freezing weather?
Follow the exact battery’s permitted temperature range and heating conditions. Do not bypass a protective cutoff or infer charge permission from air temperature alone.
