Technical blog & field answersthe 30 questions buyers actually search

The African passenger basis of 65–80 Wh/km gives 110–130 km, with a 100 / 120 / 150 km capacity reverse lookup.

Five factors set the price — capacity tier and cell grade among them — with Lagos, Abuja and Makurdi duty cycles compared. No figures quoted.

Why identical packs land at different cost: KEBS / PVoC and M-Pesa PAYGO against SLS 1656 / DMT and a 140–280V grid.

Putting 150Ah back into its voltage platform and passenger duty, with typical mileage at 48V, 60V and 72V.

Cycles turned into years: 3,500 for LiFePO4 against 300–500 for lead-acid — 7–9 years versus 10–17 months at one cycle a day — plus how to read SOH before replacing.

Power and capacity are different numbers: 3000W at the axle draws about 58.6A on the 16S platform and 39.1A on 24S, with a power–platform–capacity table and the reverse calculation.

A midday collapse is not a dead pack: the diagnostic order from capacity sizing and 45°C derating to charging policy.

How CC-CV curves handshake with the BMS, and how long 10A, 20A and 30A chargers take to fill a 100Ah pack.

At equal nominal capacity lead-acid runs about 240 kg against about 81 kg for lithium — what the 160 kg buys you.

How payload and road conditions in Nigeria, Kenya and Ghana move the same capacity tier up a step — still no amounts.

Capacity and voltage selection for Manila stop-start duty against longer inter-provincial runs.

E-loader is the Indian term for a cargo three-wheeler: work back from rated payload and climbing current to 72V 160–200Ah.

Not a failed pack: the step-by-step order from transient voltage sag to BMS over-current limits and controller current limiting.

Three steps from payload, gradient and daily distance to a voltage platform, and why 72V on a light vehicle does not pay.

The same 45Ah badge is 2.30 kWh at 60V and 3.46 kWh at 72V, with the Ah-to-kWh-to-kilometres conversion and four selection steps.

Folding electricity, cycle life and replacement count into a per-kilometre figure rather than comparing purchase prices.

How the interface, locking and handshake decide whether you can charge upstairs or join a swap network.

How market access, payment route and road conditions change the landed cost of the same capacity tier.

Five common concerns taken one at a time: heat, overcharge, deep discharge, fitment and service.

The standard five-step order: measuring the donor, positioning the pack, wiring the controller and inspecting the chassis.

How much of the total sits in the pack, motor, controller, harness and labour — and which saving buys back workshop visits.

Why the same conversion lands at different cost in the two regions: market access, sea freight and local labour.

Who owns the pack, pay-per-swap against monthly rental, and how the fleet handshakes with the cabinet.

Calculated live from daily distance, fuel price and electricity price, and where the 6–8 month range comes from.

The controller and charger compatibility list: what can stay, what must change, and what burns a board if it does not.

Measure the bay before choosing capacity: length, width, height, cable exit direction and mounting points in order.

Standby pack count follows daily swap volume and charge rate; the four figures to fix before designing a site.

After a protection trip, work through temperature, cell voltage delta and charger handshake — before opening the pack.

UN38.3, MSDS and the packing certificate are the shipping floor; market access is tiered by destination in one table.

On an 11-hour night a 20A unit fills one 150Ah pack or two 100Ah packs — and 10A never finishes a 150Ah. Includes kW per bay and the swap crossover.
