Maxpower MP-5000 5.12 kWh Lithium Battery (48V class)

The Maxpower MP-5000 is a 5.12 kWh (51.2V, 100Ah) LiFePO4 wall-mount battery from Lahore's Maxell Power (Pvt) Ltd, and the volume seller of the brand's lithium range. As of 2 August 2026 it retails for Rs 245,000-260,000 across four independent Pakistani retailers.

It is the standard "one-battery" pairing for a 5-6 kW hybrid inverter: 48 kg on the wall, roughly 4.1 kWh of usable overnight backup at 80% depth of discharge, and a claimed 6,000-cycle life whose only enforceable backing is the dealer-quoted 5-year warranty.

Honest assessment

Pros. The price is the argument: Rs 245,000-260,000 (2 August 2026) buys the same nameplate energy that costs Rs 280,000-310,000 in a Pylontech UF5000, and availability across Lahore-based retailers is good. The 100A discharge rating means it can actually feed a 5 kW hybrid at full tilt, which some budget 5 kWh packs cannot. The official Alpha page publishes real numbers — charge/discharge currents, parallel limit of 15, weight, dimensions — rather than pure marketing.

Cons. Nobody will tell you whose cells are inside, and without a named cell maker the 6,000-cycle claim is unverifiable — note that Max Power's own May 2026 article says 8,000 cycles for the same line, a contradiction the company leaves standing. Usable energy and DoD are simply not published. The model naming actively works against buyers: "MP-5000" covers a 51.2V/100Ah Alpha, a 51.2V/102Ah legacy Ultra still common in shops, and a 25.6V/200Ah PRO — electrically different products under one number. And the 50A charge limit means a full recharge from solar takes about 2 hours at best, longer in practice — fine for daily cycling, slower than the 100A-charge rivals.

Who should buy. Buyers on a 5-6 kW hybrid from the published compatibility list who want maximum kWh per rupee from a locally-serviced brand and will get the warranty procedure in writing. If documented cell provenance matters more than the ~Rs 40,000 saving, buy Pylontech; if the budget is tighter still, Fronus lists a 5.12 kWh unit at Rs 185,000 — with its own trade-offs covered in our Fronus guide.

Pakistan reality check

Heat. LiFePO4 is the right chemistry for Punjab and Sindh summers — it tolerates heat far better than other lithium types — but the published charge window tops out at 55°C cell temperature and the pack is IP20: indoor, ventilated, out of direct sun. A battery in a west-facing garage hits derating territory in June. Cycle-life claims are lab numbers at 25°C; expect real Pakistani duty to land under them, which is one more reason the 5-year written warranty matters more than the 6,000-cycle sticker. Our battery-life guide covers the heat math.

The BMS handshake. Run the battery on CAN or RS485 with the inverter, not on dumb voltage mode. Maxpower publishes its compatibility list on the PRO pages (Solis, Growatt, Sofar, GoodWe, SMA, Deye and others); the Alpha page advertises Bluetooth monitoring but does not restate the protocol list, so make protocol confirmation for your exact inverter a condition of sale, cable included. Tubular-to-lithium upgrades fail on this exact point more than on anything else.

Variant check at the counter. Ask which unit is physically in the box: Alpha (current), Ultra (legacy, off the official catalogue but still sold), or PRO (25.6V — wrong voltage class for a 48V inverter unless you are building a 24V system). The serial and model label on the unit must match the invoice; a "same thing, brother" answer is not acceptable at Rs 250,000.

Warranty claim reality. Five years via the selling dealer, honoured by Maxell Power in Lahore. Buyers in Karachi, Islamabad or smaller cities should ask in writing who swaps a failed unit locally and on what timeline — we could find no published service-centre list. An absent paper trail is the single most common reason lithium warranty claims die in Pakistan; see the warranty reality table.

Price context vs rivals (August 2026)

Rival prices from SolarPanelRates' lithium list (updated 14 July 2026, checked 2 August 2026). The MP-5000 sits mid-market: a real saving against the imported tier, a premium over the cheapest local badges, with cell provenance as the invisible line item. If your loads justify 10 kWh, the MP-10000 is meaningfully cheaper per kWh (Rs ~43,000 vs ~49,000).
