The double-capacity wall unit: 10.24kWh in the same 145mm depth, with a 200A discharge option for homes that draw hard.
The IMP-LW-10B doubles the powerwall: 51.2V, 200Ah, 10.24kWh in an 800 × 550 × 145mm cabinet at about 86kg. The electrical story matches its sister — 58.4V charge, 43V cut-off, 6,000 cycles or more at 80% DOD, 20A/50A standard currents — with one headline upgrade: maximum continuous charge and discharge of 100A, and 200A available as an option for high-draw installations.
Ten kilowatt-hours on a wall changes the conversation from 'backup for essentials' to 'the house runs normally'. Evening cooking, water heating on a timer, workshop tools, a home office through a daytime outage — the loads that force a generator start on a 5kWh system stay on battery here. Fifteen modules parallel, as across the powerwall line, so the ceiling is architectural rather than electrical. Communication is RS232, RS485 or CAN; Bluetooth, Wi-Fi and heater are published options; temperature windows run 0–55°C charging and −20–65°C discharging.
Distributors position the 10B as the single-unit answer for family homes — one cabinet, one install visit, a datasheet that closes the technical sale. Where the brief outgrows a wall entirely, the same platform continues into the stackable and rack ranges without changing supplier.

Figures are the manufacturer's published data for this range. The written quote states the exact configuration of your build.
For homes with simultaneous heavy loads, the 200A build removes current as the sizing constraint — an order-level option, stated in the quote.
10.24kWh in a single wall cabinet covers the brief most installers meet weekly, with no stack or rack to build.
Same 145mm depth and mounting logic as the 05B — a two-SKU residential wall range with one install pattern.
Parallel growth stays available for the homes that later add an EV or a second building.
Two matched 10B units in parallel give 20.48kWh on the wall; beyond three or four units, floor space economics usually favour the stackable or rack formats. The honest route is to size from the load list: send it with the enquiry and the quote states the unit count and format the numbers support — including when that answer is 'one is enough'.
Minimum order quantities and lead times depend on the product type and the degree of customisation: standard products can start from smaller batches, while custom housings, labelling and packaging are assessed per project. Samples can be arranged, with sample and freight costs confirmed against the requirement. Every enquiry is answered with a written specification and quote stating the model, configuration and terms - nothing about an order here is left to chat messages.
Improve Battery runs OEM/ODM alongside its standard range, and ships with the export documentation each model carries (CE, RoHS, FCC, MSDS, UN38.3 types as listed per datasheet; certificates available upon request). State the model, voltage, quantity and destination in the enquiry form and the sales team in Shenzhen will reply with the full specification.
It raises maximum continuous charge and discharge from 100A to 200A for high-draw homes. It is a build option confirmed in the written specification, not a field upgrade.
Parallel strings should be matched models. The quote configures matched units or separate strings for mixed briefs.
About 86kg plus bracket — a two-person lift onto a structural wall. Mounting requirements are confirmed against your wall type at quote stage.
Model, voltage, quantity and destination - that is all a real quote needs.
