BIDDING STARTS AT R1 NO RESERVE HIGHEST BID WINS
A 19" rack-mount lithium iron phosphate battery built for solar, backup power and off-grid systems 2.56 kWh in a 3U metal chassis with a full protection BMS on board, going out on a genuine R1 no-reserve auction.
This unit is certified used with 200 running hours on it. It came out of a working installation, has been bench-tested and health-checked before listing, and is cosmetically and electrically sound. At roughly 40 cycles used out of a rated 3000, it has spent about 1% of its design life you are buying a battery that is, electrically, still effectively new, at used money.
WHY LiFePO4 OVER LEAD-ACID
- 3000 cycles at 80% DOD roughly 8+ years of daily cycling, versus 300500 cycles from a typical lead-acid bank
- Use ~8090% of the capacity, not the ~50% you are limited to on lead-acid 2.56 kWh here does the work of a much bigger AGM bank
- 20 kg for 2.56 kWh a fraction of the weight and footprint
- No maintenance, no gassing, no watering, no equalising
- LiFePO4 chemistry the safest, most thermally stable lithium chemistry on the market

BUILT-IN BMS PROTECTION
The onboard Battery Management System protects against:
- Over-charging
- Over-discharging
- Over-current
- Short circuit
- Temperature extremes (charge and discharge cut-off + reconnect)
Cell balancing keeps all 32 cells matched so the pack ages evenly.
