LiFePO4 Lithium Batteries: Connection, Safety, and Charging Guide
24/03/2026
"How do I connect my batteries?" — this is the most frequent question before installation. Here you will find the answer simply and clearly.
Why LiFePO4 and not other chemistry?
- ✅ Safest chemistry — does not burn or explode
- ✅ 6,000 cycles — 10+ years
- ✅ Withstands high temperatures and salty environments
- ✅ Environmentally friendly
Series vs. Parallel Connection
| Connection Type | Result | Usage |
|---|---|---|
| Series | Increases voltage | 12V → 24V → 48V |
| Parallel | Increases capacity | 100Ah → 200Ah → 300Ah |
| Series + Parallel | Increases both | Complex systems |
Real-life example
Kostas in Crete wanted a 48V/200Ah system. He purchased 4x Pytes V5 48V/100Ah in parallel. They were connected with a Victron MultiPlus-II 48V. Result: 20kWh storage for complete autonomy.
💡 Safety Tip: Always use a BMS (Battery Management System). The Pytes V5 have an integrated BMS and communicate via CAN bus with the Victron.
FAQ
Do I need a separate BMS?
Not if you use batteries with an integrated BMS like the Pytes V5.
Can I mix different brands of batteries?
No! Always use batteries of the same brand, capacity, and age.How deep of a discharge is allowed?
LiFePO4 allows 80-90% depth of discharge without damaging the lifespan.
