LiFePO4 batteries from a dozen brands all look similar on a spec sheet. What separates them is BMS quality, warranty support, and what happens when something goes wrong. Here's the honest breakdown.
Top picks
Battle Born 100Ah ($1,050) — Premium choice
The gold standard for van builds. Battle Born batteries have:
- A proven, conservative BMS that rarely trips on legitimate loads
- 10-year warranty with US-based customer support (Reno, Nevada)
- Drop-in Group 27 form factor (fits most battery boxes)
- 100A continuous discharge, 200A peak
Why the premium is worth it: Battle Born's warranty service is real — they replace batteries that fail, no runaround. For a full-time van lifer where the battery is mission-critical, this matters. The higher price is partly a warranty and support premium.
Best for: Full-time van life, builds where failure is unacceptable, high-discharge applications.
LiTime 100Ah ($280) — Best value
LiTime (formerly Ampere Time) is the most popular "value" LiFePO4 for van builds and earned its reputation:
- Consistent BMS performance in community testing
- 5-year warranty with responsive US customer support
- 100A continuous discharge, 200A peak
- Widely available on Amazon with fast shipping
At ~$280 vs Battle Born's $1,050, you're getting 80% of the battery for 25% of the price. The BMS is less conservative and the warranty is shorter, but for most van builders it's an excellent choice.
Best for: Budget-conscious builders, first builds, weekend use.
SOK 100Ah ($320) — Community favorite
SOK has a strong following in the van and RV community:
- Marine-grade build quality, IP65-rated
- Bluetooth monitoring built in (some models)
- 200A BMS — handles high-discharge loads well
- 5-year warranty
Priced between LiTime and Battle Born. The IP65 rating and Bluetooth monitoring add genuine value for van applications.
Best for: Builders who want Bluetooth monitoring and durable construction without the Battle Born price.
Renogy 100Ah LiFePO4 ($350) — Ecosystem play
Renogy's lithium batteries integrate with their solar and charging ecosystem via Bluetooth and can be managed alongside Renogy's MPPT controllers and DC-DC chargers:
- 100A continuous discharge
- Bluetooth monitoring
- Integrates with Renogy BT-2 module and app
Worth considering if your entire system is Renogy — the integration is convenient. Priced similarly to SOK.
Chins / Weize 100Ah ($200–$230) — True budget
These no-frills options work and have positive reviews, but:
- Shorter warranties (1–2 years)
- Less rigorous BMS protection
- Limited US customer support
Fine for a weekend build where the consequence of failure is inconvenience rather than being stranded.
200Ah options
| Brand | 200Ah price | Notes |
|---|---|---|
| Battle Born | ~$2,100 (2× 100Ah) | Two batteries in parallel |
| LiTime | ~$480 | Single 200Ah unit; good value |
| SOK | ~$580 | Single 200Ah with BT |
| Renogy | ~$650 | Single 200Ah with BT |
