Yachu 12.8V 200AH battery

KSh 45,500.00

12.8 V nominal voltage: This is a common nominal voltage for lithium-based (or “12 V-class”) battery banks.
200 Ah capacity: Indicates the battery can (in ideal conditions) supply 200 amperes for 1 hour — or for example, 20 A for 10 hours, 5 A for 40 hours, etc
Energy storage ~ 2.56 kWh: Multiplying capacity × voltage roughly gives energy storage of 12.8 V × 200 Ah ≈ 2,560 Wh (≈ 2.56 kWh).
Lithium-based & Deep-Cycle (LiFePO₄): According to the seller, this battery uses lithium iron phosphate (LiFePO₄) chemistry — meaning it’s lighter, maintenance-free, and has a more stable output vs traditional lead-acid.
Built-in BMS & high cycle life: It includes a Battery Management System (BMS) that protects against overcharge / over-discharge / short-circuit / overheating — and is rated for thousands of charge/discharge cycles (many sources say 6000+ cycles at ~80% depth-of-discharge) which gives much longer useful life than typical lead-acid batteries.

Here are rough estimates (assuming a conservative ~80% usable capacity and before inverter losses if converting to AC):

Load / Use case	Approx runtime
A few LED bulbs + Wi-Fi router / lights (~50 W)	~40–45 hours
TV + router or laptop (~100–150 W)	~15–20 hours
Small DC fridge or fan (~100 W)	~20–25 hours (intermittent use)
Medium AC appliance (inverter + 200 W load)	~10–12 hours (DC power ~2400 Wh × 80% ÷ 200 W ≈ 9.6 h, before inefficiencies)

These are rough — actual runtime depends a lot on load type (AC vs DC), inverter/efficiency losses, age & temperature.

Pros

Much higher usable capacity and energy compared to small 12 V / 55 Ah batteries — good for home backup, solar storage, off-grid power, or heavier loads.
Long cycle life: Thousands of cycles means it’s cost-effective over years of use.
Maintenance-free & safer: With LiFePO₄ chemistry + built-in BMS, you don’t need to check water levels or worry about acid spills (unlike flooded lead-acid) — safer and cleaner.
Good for solar / inverter systems: Ideal for solar panel setups, off-grid homes, backup power during outages, or medium–large energy needs.
